V Urgent : Debugging an RFC function Module in another R/3 system

Former Member

Hi All

I have a function module in a R/3 system ( say WB1 ) and i am calling it from another R/3 system (say WD1) . Both have their RFC destinations set up as trusted system mutually . However when i try to debug that FM while in WD1 ( which basically exists only in WB1) i am not able to get inside that FM . Are there some settings that we need to do to allow us to debug function module in another R/3 system ? .

Yes ,we cant do this debugging if RFC function module is in a non SAP system but am sure it can be done atleast for R/3 to R/3 .

Any pointers to this as to what setting needs to done ?

Does some system parameter needs to be set in RSPARAM program for debugging RFC?

Please help

Can you do a remote logon through the SM59 connection (the trusted one)?

If so, then the only thing preventing you would be debugging autorization.

If not, make sure you have trusted system logon auth (not part of SAP_ALL!).
