Q. How to know whether a given function module is normal or RFC function module?

1) Go to SE37.

2) Enter the name of the function module you are provided.

3) Click on DISPLAY

4) Choose Attributes tab

5) Under this tab, you can see Processing Type block.

6) If remote-enabled module is checked, then it is RFC otherwise normal function
module.


Q. How many types of RFCs are there?

There are five types of RFCs-

1) Synchronous RFC

2) Asynchronous RFC

3) Transactional RFC

4) Queued RFC

5) Parallel RFC


Synchronous RFC:

It is the very common method used in real business scenarios. Both the client
and server must be available in this type of RFC.

The advantage is that you can get the result immediately, which means the RFC
function module gives result or output immediately.


The syntax is

CALL FUNCTION DESTINATION name>
In next post we will discuss all other RFC types.
