When reading the message check the delivery count. If greater than threshold put message to backout queue and commit.
Enjoy

still apply (though I accept unreservedly that this question is entirely relevant to this forum). As a general point you need to obtain better training and/or materials. This question is about as basic as CICS debugging is on mainframe.
You will not get quality knowledge via this route.
