how to avoid BPM SYSFAILerror in queue

Hi Friends,

I just designed a sync/asynch bridge. sender abap proxy synch...

whenever there is any failure, the message goes to sysfail status in smq2 and sxmb_moni. I am using dedeline/exception branch also ?

I just want to make sure if any message fails it should be visible only in SXMB_MONI and should not block any queue with sysfail error.

Anyway to achieve it ?
