TRFC error in sending IDOC

Hi

I just finished setting up my system to send vendor IDOCs (CREMAS) to an external XI system. i used BD14 to do it. the status shows 3 in WE05 but the XI system doesn't receive any idoc from R/3. When i check SM58 i see that there are errors and the status text shows ::000. When i try processing them manually from SM58 i get the msg "Function module does not exist or EXCEPTION raised".

I found a post on the forum and tried following the note 837595 for authorisations. But my userid has the profile SAP_ALL and all the field name values for the authorisation object according to the note is *, and i still face the problem. Should i change field values for the authorisation object??

Regards
