Permanent error in BPE inbound processing

Hello everybody!

I have IP1 (Integration Process) sending an async message to IP2. IP2 activates and uses a correlation.

Well, everything works fine most of the time. But randomly (and not frequently) I'm facing a SYSFAIL due to "Permanent error in BPE inbound processing" in IP2's queue. When this happens I simply use "Active Queue" button (SMQ2) and the message is properly processed.

Here, are some other information about the error:

Error during delivery of message XXXX to receive process

EXCEPTION NAME = CX_SWF_INBOUND_PERMANENT

METHOD DELIVER_MESSAGE

METHOD FILTER_EVENT_ITEMS

METHOD CHECK_PROCESS
