Output message determination ME (653 E)

Hello Gurus,

I need to print a lable when the goods receipt is posted from customer return. I manage the customer return using outbound delivery (VL02N).

I set a MM message (ME inventory management) ZXXX that uses the following access sequences:

VGART Trans./Event Type

WEVER Print Version

KZDRU Print Item

WERKS Plant

I have two type of customer return:

1) material is owned by company (mov.type653)

2) material is owned by customer (mov.type 653 E)

When I posted the return for the first kind the output message is correctly determined, but when I post 653 E no output message ZXXX is determined.

Why if I use movement with special stock it doesn't work?

Thank you in advance
