I am facing a peculiar issue in Prod environment for one of my Interfaces.Around 1100 IDOCs were triggered from R/3 system and they were successfully sent out of R/3(status 03) but in XI where we are using a BPM for collecting the IDOCs , only 350 idocs have been successfully processed out of the PE while around 750 idocs are still waiting to be processed from the outbound side of BPM( the PE status is WAIT). Also the workflow steps are successfully executed but still the messages are not out of the BPM. As far as I understand there would be some internal error in processing of the message from BPE to IS . If thats the case,is there some way out get these messages out of BPM. Is there any way to Refresh the BPE cache? I dont want to resend the idocs again from R/3 and cancelling the old messages which are stuck in BPM in XI. Please suggest the right solution and do response immediately as the issue is critical.
