Response message error in queue when using ABAP proxy

[susan_pfab]

I am using an abap proxy for the first time, and some of the response messages are getting stuck in the sender's (R/3) inbound queue. To resolve them, I have to either reset the status or execute the LUW. Sometimes, this doesn't even work.

Here is my "asynchronous" scenario:

R/3 -> <proxy> -> PI -> <file adapter> -> File

The R/3 system that I'm using has not used PI before, so I'm thinking something is missing from the set-up on the R/3 side. On the errors I finally do get to process, I get the following error in the SXMB_MONI on the sender (R/3) side (the PI SXMB_MONI shows successful). Can someone help me understand what a response message is and how it is different from an acknowledgement? Also, help me to understand what could be causing the response messages to get stuck in the R/3 queue.

Looks like you are not assigning the response conrrectly to the output strucuture of the proxy..!!

Could you be more specific. I'm assuming you're talking about populating more of the output structure when I'm calling the abap proxy. What do I need to do?
