Goods Receipt Output Control

Dear experts,

I'm trying to extend the Inventory Management with my own output type. The goal is to output some output type after the standard one in goods receips log (transaction /nme23n --> Output --> Processing Log). I created the program processing routine. Then I created the new access sequence, entered the accesses and their field. Finally I defined the new procedure with created condition type. It ssems that my program is not called at all. What I am missing. The message type is active (transaction BD50).

P.S.

I created the Goods Receipts in MIGO and then I go to PO (me23n) and display the purchase order history. There I find the Material Ducment that was generated after Goods Receipt creation. And afterward I go into this Material Document and display the Processing Log. And I have to enhance this log with my own logic: call the custom program.

Thank you.
