RFC Function module's where used list

[Former Member]

Dear Experts,

I have a situation where in I need to change certain parameters/ the logic of an RFC function module. but before making the changes to the function module I need to know where this function module is used in various systems. So can some one tell me a way to find the where used list of an RFC function module in the calling system.

Thanks

It could be called from anywhere, theoretically, SAP or non-SAP environments.

I hope you can rely on good documentation in your organization to find the potential callers, as each call must have been consciously implemented at some point.

Also check with system administrators who might have a means to study trace logs for information on calling systems.

P.S. the hard way would be to just do the change and see who complains later on

On the ABAP-side you could do it the "hard way": Logon to each SAP-system and run a source scan with the string of the FM name. You can do such a scan by running the report RSRSCAN1.On the non-ABAP-side you'll need some non-ABAP tool which allows to scan all Java, C, etc. sources which are used in your company.
