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.

278) What is the difference between a pool table and a transparent table and how they are stored at the database level.

Ans Pool tables are a logical representation of transparent tables. Hence no existence at database level.

Where as transparent tables are physical tables and exist at database level.

Pool Table -

4) Many to One Relationship.

6) It can hold only pooled tables.

Transparent Table –

4) One to One relationship.

5) 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.

6) It can hold Application data.


279) What is cardinality?

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
