Hi, Can someone tell me the difference between creating a web service for a Function Module vs. Function Module Group?

Thanks!

Sure Kenneth, it is really quite simple. If you create a web service based on a function module, you expose that FM via exactly one operation, think of an operation as sort of a method. If you expose an entire function group, all function modules within the group(if you select them all in that appropriate step of the wizard) will be exposed via that many operations. So just think of exposing a function group as a short cut to exposing more than one function module at one time, the function modules of one specific group.

Regards,
