311) How to schedule a Report in background? what is the use of background job please explain about it?

Ans There are 3 ways to schedule in background:

SM36

SE38

SA38

The easiest of the three is SA38.

Why background? In foreground jobs are only allowed a certain amount of runtime. Long running jobs usually times out in foreground, and have to be run background. Some customers has day-end jobs to fill custom tables, and these only run late at night, so they are scheduled as background jobs as well. There may be any of a hundred reasons why you want a job to run in background instead of foreground, and these are only 2 of them.

1) Transparent table 5) Pool table

2) Cluster table are data dictionary table objects 6) Sorted table

3) Indexed table 7) Hash table

4) Internal tables.

282) What are pooled table?

Ans Table pools (pools) and table clusters (clusters) are special table types in the ABAP Dictionary. The data from several different tables can be stored together in a table pool or table cluster. Tables assigned to a table pool or table cluster are referred to as pooled tables or cluster tables.

A table in the database in which all records from the pooled tables assigned to the table pool are stored corresponds to a table pool. The definition of a pool consists essentially of two key fields (Tabname and Varkey) and a long argument field (Vardata).

Table Clusters Several logical data records from different cluster tables can be stored together in one physical record in a table cluster.

A cluster key consists of a series of freely definable key fields and a field (Pageno) for distinguishing continuation records. A cluster also contains a long field (Vardata) that contains the contents of the data fields of the cluster tables for this key. If the data does not fit into the long field, continuation records are created. Control information on the structure of the data string is still written at the beginning of the Vardata field.

283) What are Hashed Tables?

Ans Hashed tables - This is the most appropriate type for any table where the main operation is key access. You cannot access a hashed table using its index. The response time for key access remains constant, regardless of the number of table entries. Like database tables, hashed tables always have a unique key. Hashed tables are useful if you want to construct and use an internal table, which resembles a database table or for processing large amounts of data.

SAMPLE PROG: THIS DOES NOTHING.

REPORT Z_1 .

TABLES: MARA.

DATA: I TYPE HASHED TABLE OF MARA WITH UNIQUE KEY MATNR

A logical database provides read-only access to a group of related tables to an ABAP/4 program.

Advantages: - The programmer need not worry about the primary key for each table. Because Logical database knows how the different tables relate to each other, and can issue the SELECT command with proper where clause to retrieve the data.

1) An easy-to-use standard user interface.

2) Check functions, which check that user input is complete, correct, and plausible.

3) Meaningful data selection.

4) Central authorization checks for database accesses.

5) Good read access performance while retaining the hierarchical data view determined by the application logic.

6) No need of programming for retrieval, meaning for data selection

Disadvantages: -

1) If you do not specify a logical database in the program attributes, the GET events never occur.

2) There is no ENDGET command, so the code block associated with an event ends with the next event statement (such as another GET or an END-OF-SELECTION).

3) Fast in case of lesser no. of tables But if the table is in the lowest level of hierarchy, all upper level tables should be read so performance is slower.

173) What specific statements do you using when writing a drill down report?

Ans AT LINE-SELECTION

AT USER-COMMAND

AT PF.

174) What are different tools to report data in SAP? What all have you used?

Ans

175) What are the advantages and disadvantages of ABAP query tool?

Ans Advantages: No programming knowledge is required.

Disadvantages: Depending on the complexity of the database tables, it may not be easy for the user to select the necessary data correctly.

176) What are the functional areas? User groups? How does ABAP query work in relation to

these?

Ans Functional Areas - By creating functional areas, we can initially select this data. This ensures that the data is presented to the ABAP Query user in a meaningful way to accomplish the task, and that only the data that the user may use is presented.

User Groups – A user group is a collection of users that work with about the same data and carry out similar tasks. The members of a user group can use all programs (queries) created by any user of the group. Changes to such a program are at once visible to all users. This ensures that all members of a user group use the same evaluation programs.

ABAP Query: It consists of three components – queries, functional areas and user groups. The functional areas provide the user with an initial set of data in accordance with the task to be accomplished. All users must be members of at least one user group. All members of one user group can access the same data as well as the same program (queries) to create lists.

177) Is a logical database a requirement/must to write an ABAP query?

Ans No, it is not must to use LDB. Apart from it, we have other options:

1) Table join by Basis Table

2) Direct Read of table

3) Data Retrieval by Program

178) What is the structure of a BDC sessions.

151) What happens when a table is activated in DD?

Ans When the table is activated, a physical table definition is created in the database for the table definition stored in the ABAP dictionary. The table definition is translated from the ABAP dictionary of the particular database.

It is available for any insertion, modification and updation of records by any user.

152)

Ans

153) What are matchcodes? Describe?

Ans It is similar to table index that gives list of possible values for either primary keys or non-primary keys.

154) What transactions do you use for data analysis?

Ans

155) What are the elements of selection screen?

Ans There are 5 elements of selection screen:

Selection-screen include blocks

Selection-screen include parameters

Selection-screen include select-options

~~Selection-screen include comment~~

~~Selection-screen include push-button~~

~~156) What are ranges? What are number ranges?~~

~~Ans Main function of ranges to pass data to the actual selection tables without displaying the selection screen.~~

~~Min, Max values provided in selection screens.~~

It is often necessary to directly access individual records in a data structure. This is done using unique keys. Number ranges are used to assign numbers to individual database records for a commercial object, to complete the key. Such numbers are e.g. order numbers or material master numbers.

~~157) What are select options and what is the diff from parameters?~~

~~Ans Parameters : We can enter a single value.~~

~~PARAMETERS: PARAM(10).~~

~~Select-options: We can enter low and high value i.e. range has to be specify. By using NO-INTERVAL user can process only single fields.~~

~~SELECT-OPTIONS: DNO FOR DEPT-DNO.~~

~~SELECT-OPTIONS: DNO FOR DEPT-DNO NO-INTERVAL.~~

~~SELECT-OPTIONS declares an internal table, which is automatically filled with values or ranges of values entered by the end user. For each SELECT-OPTIONS, the system creates a selection table.~~

~~SELECT-OPTIONS FOR .~~

~~A selection table is an internal table with fields SIGN, OPTION, LOW and HIGH.~~

~~The type of LOW and HIGH is the same as that of .~~

~~The SIGN field can take the following values: I Inclusive (should apply) E Exclusive (should not apply)~~

The OPTION field can take the following values: EQ Equal GT Greater than NE Not equal BT Between LE Less than or equal NB Not between LT Less than CP Contains pattern GE Greater than or equal NP No pattern.

~~Differences-~~

~~PARAMETERS allow users to enter a single value into an internal field within a report.~~

~~SELECT-OPTIONS allows users to fill an internal table with a range of values.~~

~~Select-options provide ranges where as parameters do not.~~

~~For each PARAMETERS or SELECT-OPTIONS statement you should define text elements by choosing~~

~~Goto - Text elements - Selection texts - Change.~~

~~Eg:- Parameters name(30).~~

When the user executes the ABAP/4 program, an input field for 'name' will appear on the selection screen. You can change the comments on the left side of the input fields by using text elements as described in Selection Texts.

~~158) How do you validate the selection criteria of a report? And how do you display initial values in a selection screen?~~

~~Ans The selection criteria is validated in the processing block of the AT SELECTION SCREEN event for the input values on the screen and respective messages can be sent.~~

~~To display initial values in the selection screen:~~

~~1) Use INITIALIZATION EVENT~~

~~2) Use DEFAULT VALUE option of PARAMETERS Statement~~

3) ~~Use SPA/GPA Parameters (PIDs).~~

~~Validate: - by using match code objects.~~

~~Display :- Parameters default 'xxx'.~~

~~Select-options for spfli-carrid.~~

~~Initial values in a selection screen:~~

~~INITIALIZATION.~~

~~DNO-LOW = 10.~~

~~DNO-HIGH = 30~~

~~SIGN I.~~

~~OPTION NB.~~

~~APPEND DNO.~~

~~159) What are selection texts?~~

~~Ans~~

~~160) What is CTS and what do you know about it?~~

Ans CTS stands for Correction and Transport System. The CTS provides a range of functions that help you to choose a transport strategy optimally suited to your requirements. We recommend that you follow the transport strategy while you plan and set up your system landscape.

143) What is an interactive report? What is the obvious difference of such report compared

with classical type reports?

Ans An Interactive report is a dynamic drill down report that produces the list on users choice.

Difference: -

a) The list produced by classical report doesn't allow user to interact with the system where as the list produced by interactive report allows the user to interact with the system.

B) Once a classical report, executed user looses control where as Interactive, user has control.

2008-05-12T14:27:00.000-07:00

131) How many types of tables exist and what are they in data dictionary?

Ans 4 Types of Tables:

Transparent tables - Exists with the same structure both in dictionary as well as in database exactly with the same data and fields. Both Open SQL and Native SQL can be used.
Pool tables
Cluster tables - These are logical tables that are arranged as records of transparent tables. One cannot use Native SQL on these tables (only Open SQL). They are not manageable directly using database system tools.
Internal tables

132) What is the step-by-step process to create a table in data dictionary?

Ans Steps to create a table:

Step 1: creating domains (data type, field length, Range).

Step 2: creating data elements (properties and type for a table field).

Step 3: creating tables (SE11).

133) Can a transparent table exist in data dictionary but not in the database physically?

Ans No, Transparent table do exist with the same structure both in the dictionary as well as in the database, exactly with the same data and fields.

134) In SAP Scripts, how will u link FORM with the Event Driven?

Ans In PAI, define function code and write code for the same.

135) Can you create a table with fields not referring to data elements?

Ans YES. e.g.:- ITAB LIKE SPFLI.

Here we are refering to a data object (SPFLI) not data element.

136) What is the advantage of structures? How do you use them in the ABAP programs?

Ans GLOBAL EXISTANCE (these could be used by any other program without creating it again).

137) What does an extract statement do in the ABAP program?

Ans Once you have declared the possible record types as field groups and defined their structure, you can fill the extract dataset using the following statements:

EXTRACT .

When the first EXTRACT statement occurs in a program, the system creates the extract dataset and adds the first extract record to it. In each subsequent EXTRACT statement, the new extract record is added to the dataset

EXTRACT HEADER.

When you extract the data, the record is filled with the current values of the corresponding fields.

As soon as the system has processed the first EXTRACT statement for a field group , the structure of the corresponding extract record in the extract dataset is fixed. You can no longer insert new fields into the field groups and HEADER. If you try to modify one of the field groups afterwards and use it in another EXTRACT statement, a runtime error occurs.

By processing EXTRACT statements several times using different field groups, you fill the extract dataset with records of different length and structure. Since you can modify field groups dynamically up to their first usage in an EXTRACT statement, extract datasets provide the advantage that you need not determine the structure at the beginning of the program.

138) What is a collect statement? How is it different from append?

Ans Collect : If an entry with the same key already exists, the COLLECT statement does not append a new line, but adds the contents of the numeric fields in the work area to the contents of the numeric fields in the existing entry.

Append – Duplicate entries occurs.

139) What is OPEN SQL vs NATIVE SQL?

Ans Open SQL – These statements are a subset of standard SQL. It consists of DML command (Select, Insert, Update, Delete). It can simplify and speed up database access. Buffering is partly stored in the working memory and shared memory. Data in buffer is not always up-to-date.

Native SQL – They are loosely integrated into ABAP. It allows access to all functions containing programming interface. They are not checked and converted. They are sent directly to the database system. Programs that use Native SQL are specific to the database system for which they were written. For e.g. to create or change table definition in the ABAP.

140) What does an EXEC SQL stmt do in ABAP? What is the disadvantage of using it?

Ans To use a Native SQL statement, you must precede it with the EXEC SQL statement, and follow it with the ENDEXEC statement as follows:

EXEC SQL [PERFORMING

There is no period after Native SQL statements. Furthermore, using inverted commas (") or an asterisk (*) at the beginning of a line in a native SQL statement does not introduce a comment as it would in normal ABAP syntax. You need to know whether table and field names are case-sensitive in your chosen database.

121) What is the typical structure of an ABAP program?

Ans HEADER, BODY, FOOTER.

122) What are field symbols and field groups? Have you used "component idx of structure" clause with field groups?

Ans Field Symbols – They are placeholder or symbolic names for the other fields. They do not physically reserve space for a field, but point to its contents. It can point to any data objects.

Field-symbols

Field Groups – Field groups does not reserve storage space but contains pointers to existing fields.

An extract dataset consists of a sequence of records. These records may have different structures. All records with the same structure form a record type. You must define each record type of an extract dataset as a field group, using the FIELD-GROUPS statement.

Field-groups

123) What should be the approach for writing a BDC program?

Ans STEP 1: CONVERTING THE LEGACY SYSTEM DATA TO A FLAT FILE

to internal table CALLED "CONVERSION".

STEP 2: TRANSFERING THE FLAT FILE INTO SAP SYSTEM CALLED

"SAP DATA TRANSFER".

STEP 3: DEPENDING UPON THE BDC TYPE

i) Call transaction (Write the program explicitly)

ii) Create sessions (sessions are created and processed. If success, data will transfer).

124) What is a batch input session?

Ans BATCH INPUT SESSION is an intermediate step between internal table and database table. Data along with the action is stored in session i.e. data for screen fields, to which screen it is passed, program name behind it, and how next screen is processed.

Create session – BDC_OPEN_GROUP

Insert batch input – BDC_INSERT

Close session – BDC_CLOSE_GROUP

125) What is the alternative to batch input session?

Ans Call Transaction Method & Call Dialog

126) A situation: An ABAP program creates a batch input session. We need to submit the

program and the batch session in background. How to do it?

Ans Go to SM36 and create background job by giving job name, job class and job steps

(JOB SCHEDULING)

127) What is the difference between a pool table and a transparent table and how they are

stored at the database level?

Ans Pool Table -

1) Many to One Relationship.

2) Table in the Dictionary has the different name, different number of fields, and the fields have the different name as in the R3 Table definition.

3) It can hold only pooled tables.

Transparent Table –

1) One to One relationship.

2) Table in the Dictionary has the same name, same number of fields, and the fields have the same name as in the R3 Table definition.

3) It can hold Application data.

128) What are the problems in processing batch input sessions? How is batch input process

different from processing on line?

Ans Two Problems: -

1) If the user forgets to opt for keep session then the session will be automatically removed from the session queue (log remains). However, if session is processed we may delete it manually.

2) If session processing fails, data will not be transferred to SAP database table.

129) Is Session Method, Asynchronous or Synchronous?

Ans Synchronous

130) What are the different types of data dictionary objects?

Ans Different types of data dictionary objects:

1) Tables

2) Views

3) Data elements

4) Structure

5) Domains

6) Search Helps

7) Local Objects

8) Matchcode

111) What are control events in a loop?

Ans Control level processing is allowed within a LOOP over an internal table. This means that we can divide sequences of entries into groups based on the contents of certain fields.

AT .

ENDAT.

You can react to the following control level changes:

	Meaning
FIRST	First line of the internal table
LAST	Last line of the internal table
NEW	Beginning of a group of lines with the same contents in the field and in the fields left of
END Of	End of a group of lines with the same contents in the field and in the fields left of

112) How to debugg a script?

Ans Go to SE71, give layout set name, go to utilities select debugger mode on.

113) How many maximum sessions can be open in SAPgui?

Ans There are maximum 6 sessions open in SAPgui.

114) SAP Scripts and ABAP programs are client dependent or not? Why?

Ans

115) What are System Variable?

Ans System variables have been predefined by SAP. We can use these variables in formulas or, for example, to pass on certain pieces of information to a function module. How the function called by the function module behaves depends on the type of information passed on.

At present, we can use the following system variables:

System Variable	Use	Meaning
SY_MODE	In function modules	Current mode of the PI sheet
SY_TEST	In function modules	Status of the PI sheet (test or active)
SY_ROW	In function modules	Current table line
SY_VALUE or X	Generally	Refers to the immediately preceding input value

116) Is it compulsory to use all the events in Reports?

Ans

117) What is the difference between sum and collect?

Ans Sum: You can only use this statement within a LOOP. If you use SUM in an AT - ENDAT block, the system calculates totals for the numeric fields of all lines in the current line group and writes them to the corresponding fields in the work area. If you use the SUM statement outside an AT - ENDAT block (single entry processing), the system calculates totals for the numeric fields of all lines of the internal table in each loop pass and writes them to the corresponding fields of the work area. It therefore only makes sense to use the SUM statement in AT...ENDAT blocks.

If the table contains a nested table, you cannot use the SUM statement. Neither can you use it if you are using a field symbol instead of a work area in the LOOP statement.

Collect:

118) What are session method and call transaction method and explain about them?

Ans Session method – Use the BDC_OPEN_GROUP to create a session. Once we have created a session, then we can insert the batch input data into it with BDC_INSERT. Use the BDC_INSERT to add a transaction to a batch input session. We specify the transaction that is to be started in the call to BDC_INSERT. We must provide a BDCDATA structure that contains all the data required to process the transaction completely. Use the BDC_CLOSE_GROUP to close a session after we have inserted all of our batch input data into it. Once a session is closed, it can be processed.

Call Transaction -

In this method, we use CALL TRANSACTION USING to run an SAP transaction. External data does not have to be deposited in a session for later processing. Instead, the entire batch input process takes place inline in our program.

119) If you have 10000 records in your file, which method you use in BDC?

120) What are different modes of Call Transaction method and explain them?

Ans There are three modes of Call Transaction method:

1) A – Display All Screens

2) E – Display Errors

3) N – Background Processing

101) What is the use of Table maintenance allowed?

Ans Mark the Table maintenance allowed flag if users with the corresponding authorization may change the data in the table using the Data Browser (Transaction SE16). If the data in the table should only be maintained with programs or with the table view maintenance transaction (Transaction SM30), you should not set the flag.

102) How to define Selection Screen?

Ans Parameters, Select-options & Selection-Screen

103) What are the check tables and value tables?

Ans Check Table: The ABAP Dictionary allows you to define relationships between tables using foreign keys . A dependent table is called a foreign key table, and the referenced table is called the check table. Each key field of the check table corresponds to a field in the foreign key table. These fields are called foreign key fields. One of the foreign key fields is designated as the check field for checking the validity of values. The key fields of the check table can serve as input help for the check field.

Value Table: Prior to Release 4.0, it was possible to use the value table of a domain to provide input help. This is no longer possible, primarily because unexpected results could occur if the value table had more than one key field. It was not possible to restrict the other key fields, which meant that the environment of the field was not considered, as is normal with check tables.

In cases where this kind of value help was appropriate, you can reconstruct it by creating a search help for the data elements that use the domain in question, and using the value table as the selection method.

Check table will be at field level checking.

Value table will be at domain level checking ex: scarr table is check table for carrid.

104) What is the difference between tables and structures?

Ans Tables:

1) Data is permanently stored in tables in the database.

2) Database tables are generated from them.

Structure:

1) It contains data temporarily during program run-time.

2) No Database tables are generated from it.

105) How to declare one internal table without header line without using structures?

Ans No, we cannot declare internal table without header line and without structure because it gives error “ITAB cannot be a table, a reference, a string or contain any of these object”.

Code with Header without Structure

TABLES : ZREKHA_EMP.

DATA : ITAB LIKE ZREKHA_EMP OCCURS 0 WITH HEADER LINE.

SELECT * FROM ZREKHA_EMP INTO CORRESPONDING FIELDS OF ITAB.

APPEND ITAB.

ENDSELECT.

LOOP AT ITAB.

WRITE : / ITAB-EMPNO, ITAB-EMPNAME,ITAB-DEPTNO.

ENDLOOP.

Code without Header with Structure

TABLES : ZREKHA_EMP.

DATA : BEGIN OF ITAB OCCURS 0,

EMPNO LIKE XREKHA_EMP-EMPNO,

EMPNAME LIKE XREKHA_EMP-EMPNAME,

DEPTNO LIKE XREKHA_EMP-DEPTNO,

END OF ITAB.

SELECT * FROM ZREKHA_EMP INTO CORRESPONDING FIELDS OF ITAB.

APPEND ITAB.

ENDSELECT.

LOOP AT ITAB.

WRITE : / ITAB-EMPNO, ITAB-EMPNAME,ITAB-DEPTNO.

ENDLOOP.

106) What are lock objects?

Ans Reason for Setting Lock: Suppose a travel agent want to book a flight. The customer wants to fly to a particular city with a certain airline on a certain day. The booking must only be possible if there are still free places on the flight. To avoid the possibility of overbooking, the database entry corresponding to the flight must be locked against access from other transactions. This ensures that one user can find out the number of free places, make the booking, and change the number of free places without the data being changed in the meantime by another transaction.

The R/3 System synchronizes simultaneous access of several users to the same data records with a lock mechanism. When interactive transactions are programmed, locks are set and released by calling function modules (see Function Modules for Lock Requests). These function modules are automatically generated from the definition of lock objects in the ABAP Dictionary.

Two types of Lock: Shared and Exclusive

107) What are datasets? What are the different syntaxes?

Ans The sequential files (ON APPLICATION SERVER) are called datasets. They are used for file handling in SAP.

OPEN DATASET [DATASET NAME] FOR [OUTPUT / INPUT / APPENDING]

IN [BINARY / TEXT] MODE

AT POSITION [POSITION]

MESSAGE [FIELD]

READ DATASET [DATASET NAME] INTO [FIELD]

DELETE DATASET [DATASET NAME]

CLOSE DATASET [DATASET NAME]

TRANSFER [FIELD] TO [DATASET NAME]

108) What are the events we use in dialog programming and explain them?

Ans There are two events in Dialog Programming i.e. screen:

PBO (Process Before Output) – Before the screen is displayed, the PBO event is processed.
PAI (Process After Input) – When the user interacts with the screen, the PAI event is processed.
POH (Process On Help) - are triggered when the user requests field help (F1). You can program the appropriate coding in the corresponding event blocks. At the end of processing, the system carries on processing the current screen.
POV (Process On Value) - are triggered when the user requests possible values help (F4). You can program the appropriate coding in the corresponding event blocks. At the end of processing, the system carries on processing the current screen.

109) What is the difference between OPEN_FORM and CLOSE_FORM?

Ans OPEN_FORM – This module opens layout set printing. This function must be called up before we can work with other layout set function like WRITE_FORM.

WRITE_FORM – Output text element in form window. The specified element of the layout set window entered is output. The element must be defined in the layout set.

CLOSE_FORM – End layout set printing. Form printing started with OPEN_FORM is completed. Possible closing operations on the form last opened are carried out. Form printing must be completed by this function module. If this is not carried out, nothing is printed or displayed on the screen.

110) What are the page windows? How many main windows will be there in a page window?

Ans Page Window: In this window, we define the margins for left, width, upper and height for the layout of Header, Logo, Main, & Footer.

Element

Window

83) Global and local data in function modules.

Ans

84) What are the differences between SAP memory and ABAP memory?

Ans ABAP Memory is a memory area in the internal session (roll area) of an ABAP program. Data within this area is retained within a sequence of program calls, allowing you to pass data between programs that call one another. It is also possible to pass data between sessions using SAP Memory.

SAP Memory is a memory area to which all sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session (as with ABAP memory) or to pass data from one session to another.

85) What are differences between At selection-screen and At selection-screen output?

Ans AT SELECTION-SCREEN event is triggered in the PAI of the selection screen once the ABAP runtime environment has passed all of the input data from the selection screen to the ABAP program.

AT SELECTION-SCREEN OUTPUT - This event block allows you to modify the selection screen directly before it is displayed.

86) What are the events?

Ans

87) What is get cursor field?

89) What is the difference between occurs 1 and occurs 2?

Ans

90) What is the difference between Free and Refresh?

Ans Free - You can use FREE to initialize an internal table and release its memory space without first using the REFRESH or CLEAR statement. Like REFRESH, FREE works on the table body, not on the table work area. After a FREE statement, you can address the internal table again. It still occupies the amount of memory required for its header (currently 256 bytes). When you refill the table, the system has to allocate new memory space to the lines.

Refresh - This always applies to the body of the table. As with the CLEAR statement, the memory used by the table before you initialized it remains allocated. To release the memory space, use the statement

65) What are the difference between call screen and leave screen?

Ans Call Screen: Calling a single screen is a special case of embedding a screen sequence. If you want to prevent the called screen from covering the current screen completely, you can use the CALL SCREEN statement with the STARTING AT and ENDING AT

CALL SCREEN 1000.

CALL SCREEN 1000 STARTING AT 10 10 ENDING AT 20 20.

LEAVE SCREEN statement ends the current screen and calls the subsequent screen.

LEAVE SCREEN.

LEAVE TO SCREEN 2000.

Ans

58) What is LUW?

Ans Logical Unit of Work

59) Different types of LUWs. What r they?

Ans Two types of LUW are:

1) DB LUW - A database LUW is the mechanism used by the database to ensure that its data is always consistent. A database LUW is an inseparable sequence of database operations that ends with a database commit. The database LUW is either fully executed by the database system or not at all. Once a database LUW has been successfully executed, the database will be in a consistent state. If an error occurs within a database LUW, all of the database changes since the beginning of the database LUW are reversed. This leaves the database in the state it had before the transaction started.
2) SAP LUW - A logical unit consisting of dialog steps, whose changes are written to the database in a single database LUW is called an SAP LUW. Unlike a database LUW, an SAP LUW can span several dialog steps, and be executed using a series of different work processes.

Ans UPLOAD - File transfer with dialog from presentation server file to internal table. Data which is available in a file on the presentation server is transferred in an internal table. ASCII & Binary files can be transferred.

WS_UPLOAD - To read data from the presentation server into an internal table without a user dialog, use the function module WS_UPLOAD. The most important parameters are listed below.

Parameters	Function
CODEPAGE	Only for upload under DOS: Value IBM
FILENAME	Filename
FILETYPE	File type

27) Why did u switch to SAP?

Ans

28) What is a Logical Database?

Ans Logical Databases are special ABAP programs that retrieve data and make it available to application programs.

Use of LDB – is used to read data from database tables by linking them to executable ABAP programs.

29) What are the events used for Logical Database?

Ans Two Events –

1) GET - This is the most important event for executable programs that use a logical database. It occurs when the logical database has read a line from the node and made it available to the program in the work area declared using the statement NODES

The depth to which the logical database is read is determined by the GET statements.

2) PUT - The PUT statement directs the program flow according to the structure of

the logical database.

30) What is the difference between Get and Get Late?

Ans GET - After the logical database has read an entry from the node

.

GET LATE - After all of the nodes of the logical database have been processed that are below

in the database hierarchy.

31) What are the data types of Internal Tables?

23) What is SAP Script? What is the purpose of SAP Script? Difference between
SAP Script and Report?

Ans SAP Script – It is the integrated text management system of the SAP R/3 System. Two types – PC Editor & Line Editor.

Reports - It is the way to display data fetched from database table onto screen or directly output it to a printer. Two types – Classical and Interactive.

24) What is the use of occurs in internal table? Can u change occurs value in program?

Ans Use of Occurs - If you use the OCCURS parameter, the value of the INITIAL SIZE of the table is returned to the variable

Data : Begin of ITAB occurs 0,

End of ITAB.

Occurs or Initial Size – to specify the initial amount of memory that should be assigned to the table.

Yes, we can change the occurs value in program but output remains the same.

25) Difference between SY-TABIX and SY-INDEX? Where it is used? Can u check SY-SUBRC after perform?

Ans SY-TABIX - Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.

APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.

COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.

LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.

READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.

SEARCH FOR sets SY-TABIX to the index of the table line in which the search string is found.

SY_INDEX - In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.

21) What do you know about a client?

Ans

22) What are the system fields? Explain?

Ans The ABAP system fields are active in all ABAP programs. They are filled by the runtime

environment, and you can query their values in a program to find out particular states of the

system. Although they are variables, you should not assign your own values to them, since this

may overwrite information that is important for the normal running of the program. However,

there are some isolated cases in which you may need to overwrite a system variable.

For example, by assigning a new value to the field SY-LSIND, you can control navigation within

details lists.

11) Can u print decimals in type N? What is difference between float and packed data type?

Ans No, we cannot print decimals in type N because decimal places are not permitted with N

data type.

Float Data Type: It cannot be declared in Parameters.

Packed Number: It can be declared in Parameters. For e.g.

PARAMETERS : A(4) TYPE P DECIMALS 2,

B(4) TYPE P DECIMALS 2.

DATA : C(4) TYPE P DECIMALS 2.

C = A + B.

WRITE : / ‘THE SUM IS’ , C.

12) What is step-loop? Explain all the steps?

Ans A step loop is a repeated series of field-blocks in a screen. Each block can contain one or more fields, and can extend over more than one line on the screen.

Step loops as structures in a screen do not have individual names. The screen can contain more than one step-loop, but if so, you must program the LOOP...ENDLOOPs in the flow logic accordingly. The ordering of the LOOP...ENDLOOPs must exactly parallel the order of the step loops in the screen. The ordering tells the system which loop processing to apply to which loop. Step loops in a screen are ordered primarily by screen row, and secondarily by screen column.

Transaction TZ61 (development class SDWA) implements a step loop version of the table you saw in transaction TZ60.

Static and Dynamic Step Loops

Step loops fall into two classes: static and dynamic. Static step loops have a fixed size that cannot be changed at runtime. Dynamic step loops are variable in size. If the user re-sizes the window, the system automatically increases or decreases the number of step loop blocks displayed. In any given screen, you can define any number of static step loops, but only a single dynamic one.

You specify the class for a step loop in the Screen Painter. Each loop in a screen has the attributes Looptype (fixed=static, variable=dynamic) and Loopcount. If a loop is fixed, the Loopcount tells the number of loop-blocks displayed for the loop. This number can never change.

Programming with static and dynamic step loops is essentially the same. You can use both the LOOP and LOOP AT statements for both types.

Looping in a Step Loop

When you use LOOP AT with a step loop, the system automatically displays the step loop with vertical scroll bars. The scroll bars, and the updated (scrolled) table display, are managed by the system.

Use the following additional parameters if desired:

FROM and TO
CURSOR
