BPM: Error during delivery of message XXX to receive processes

Dear all,

I created a ccBPM that collects Invocies for 5 Minutes, append them as one message and send it every 5 Minutes to

a receiver.

Unfortunatelly, the message stucks in outbound queue. In sxmb_moni, the column OutbStatus got a green flag.

When clicking on PE the Inbound Queue monitor open. So no process get starting.

The queue stucks with error: Permanent error in BPE inbound processing

and I can open the "LUW data" and click on "Simulate Message Delivery" where I got this error:

"Error during delivery of message XXX to receive processes"

Clicking on correlation, I got this data:

<?xml version="1.0" encoding="utf-8" ?>

</CorrelationKey>

In previous version of the integration process, the BELNR was a correlation ID, but I changed it an nowhere in ccBPM

BELNR still exists.

So I think that the process stucks because he still trys to fill the correlaiton BELNR, but I deleted cache, I did a change on

BPM and reactivate it, but still got this error.

Anyone an idea, what else I can do to check it??

How to test the ccBPM with correlation??

How to make sure, that he uses the actual ccBPM version?

Thanks

Chris
