ABAP Functional Module

Post by Mit5252 » Mon Feb 23, 2015 11:32 am

Hello All

Can anyone tell me, why do we need to built custom ABAP functional module. I am trying to understand the business need that requires
custom ABAP functional module. And also what is the difference between ABAP functional module and class interface.

Thanks you all.

Function module, you mean?
Well, you don't have to, you could use class methods - except for the many customizing points and processes (IDocs, for example) that expect a function module.
Also, you can include dynpros in a function group, you can't have them in a class.

It's not a business need, it's a technical need.

Other technical reasons for using a Function Module over a Class / Method are:
* RFC calls; and

These have no equivalent in ABAP Objects.

Award cash if useful.
