Error Trace

Dear All,

Could you guys share with me based on your experience how we know what are the exactly errors in one scenario integration when let say the result not as per our expected.

Maybe there's a step by step to trace where are the errors. Because this is integration scenario. The errors can be come from many parties.

I just done one scenario RFC --> XI --> File.

RFC executed successfully in R/3 but when i go to SXMB_MONI t-code in XI there's no message shown.

I have no idea, how i can trace where is the error why the message is not created.

Thanks in Advance,

Victor.
