Reg: variables not getting populated at run time


Scenario: We are using As2 connectivity for EDI transactions. Partner
sends us EDI files to wM TN and we process the files (inbound)

Every thing is going smoothly, sending backMDN, decrypting, invoking processing rule service and processing.
The problem is when the flow goes from end-end, a variable is not getting submitted at run time and is throwing exception. When I trace or reprocess, the service works fine. Error occurs only in the complete cycle
– user sends file and wM service kicking of by processing rule –
When we reprocess the failed service, this time the svc works fine.

Any clue about this pls

what is the exception you are getting in real-time?
