I have a straight forward HTTP - > RFC interface. The end user states they are getting a HTTP 500 error. It's as if the process has been cancelled/aborted. This processing has been working for the past month without incident. Nothing has been changed.
Checking SXMB_MONI I can see a small grey dot next to the message. Checking RTWB it's status is 'To Be Delivered'. I've checked SMQ1/SMQ2 and there is nothing queued.
Where else can I check to see what caused the failure. Is there anyway I can recover the data the message should have returned from SAP. I can't see anything in RTWB.
Many thanks
