Types of Function Modules

[Former Member]

Hi all ,

Can any one explain the Types of Function Modules.

Hi,

Function modules are one element. There are no types. However sometimes an RFC enabled function module is referred to as RFC Function module, but really it is just a function module. Also BAPIs are function modules, but are usually referred to as just BAPI as opposed to BAPI Function module.

There is no different function module types , but calling the function module will be different.

check this function calls syntax

1. Calls a function module:

- CALL FUNCTION func.

2. Call a function module in a different mode (asynchronous Remote Function Call):

- CALL FUNCTION func STARTING NEW TASK taskname.

3. Call a function module in the update task:

- CALL FUNCTION func IN UPDATE TASK.

4. Call a function module in a remote system (Remote Function Call, RFC 😞

- CALL FUNCTION func DESTINATION dest.

5. Asynchronous call to a function module with transactional processing (transactional Remote Function Call):

- CALL FUNCTION func IN BACKGROUND TASK.

qRFC with output queue

6. Call a function module that can be activated in the context of enhancements:

- CALL CUSTOMER-FUNCTION func.

Hi Sachin.

Open any FM in SE37.

Select the Attributes Tab:

in The Processing Type you can see the Types of FMs

1.Normal FM - Can be called within the Same SAP System

CALL FUNCTION '<NAME>'

2. Remote Enable FM : Can be called from External (SAP or NON SAP) system.

CALL FUNCTION '<NAME>' DESTINATION '<RFC DESTINATION>'

3. Update Module: Only for Updating database tables . processed in Update work process.

CALL FUNCTION '<FM>' IN UPDATE TASK.
