Doubt in RFC Function module

Former Member — Fri, 19 Dec 2008 05:31:23 GMT

Hi All,

i jave created a RFC enabled function module which is working fine.

I have a small doubt in the FM, i.e. If i need to use this FM i need to have it in source system and target system. But without having it in the sorce system i can access this and fetch the data.

Will that create any problem. Or do i need to create the FM in the source and target system also...

Thanks

Ram M

hi,

you donot need to create in both the systems.

The RFC destination itself will call and read the data

from the other system.

Hi,

The RFC should be available only in SAP System.

In the target system build the logic to logon to sap system & to call the RFC with necessary parameters.

Best regards,

Prashant

If you make an RFC call from system A to system B, then

the remote function module must exist in system B.

If system A is non SAP system then the remote function module need not exist in it as explained above.

However if system A is SAP system, then your Function Module must be created in this system as well. Otherwise your calling program will give syntax error.

No it won't. There's no syntax check that a function module exists.

To the original poster - why don't you just TRY it, and see if it works?
