Remote Function Call (RFC) & types of RFC’s in SAP ABAP.

 What is Remote Function Call (RFC) & types of RFC’s?

Ans:

Ø  It is a SAP specific protocol to provide communication between different systems.

Ø  It is the process of calling Function modules from another system.

Ø  SAP Uses CPIC (Common Programming Interface for Communication) Protocol to transfer data between Systems.

                Types:

                1. Synchronous RFC: In case of this RFC both the Sender/Source and Receiver/Target                      systems should be available while distributing the data. The next part of calling program     isn’t continued until call function is completed.

            2. Asynchronous RFC: In case of this RFC both the Sender/Source and Receiver/Target                    systems should not be available while distributing the data. The next part of calling                            program is continued without completing call function.

            3. Transactional RFC (TRFC): It is almost similar to Asynchronous RFC. The Transactional              RFC is executed only once in an RFC server & save the corresponding data under unique                transaction ID in the Database.

            4. Queued RFC: In case of this RFC the multiple transactional RFC’s are serialized in the                                sequence using the Function module ‘TRFC_SET_QUEUE_NAME’.

Ø  An additional statement ‘Destination’ is used while calling Remote Enabled Functions.

RFC Function Module Create step by step in sap ABAP.

• RFC Function Module Create step by step in sap ABAP.
• Go to T-code-SE37
• At first created function group.
• If function group not created that time first create function group.
• At first go to T-code-:-SE37=>Go to=>Function group=>Create Group

• BAPI MATERIAL CREATION........................

1.  If function group already has created so you can selected your created function group.

• After that give function module name next select create option.

• After that select remote enable module option and also give the short text.   Program name and include option automatically created.

•  Go to import tab

•  Go to tables tab

BAPI MATERIAL CREATION........................

After that go to Source Code
