EDI - IDOC

Hi All:

I am using VF02(Billing) Transaction to generate the EDI-IDOC.

In that I am using ZRD3 Output Type(Invoice). When i enter this O/P type in VF02 -> Goto -> Header -> Output then Save the Application the IDOC will be created.

I am using IDOC_OUTPUT_INVOIC Function Module (Process Code SD09).

My Problem is . In the Idoc E!EDP08 Segment didn't populated .

so, How can i debug and trace this while updating data in the segment .

If i put a Brak-Point in IDOC_OUTPUT_INVOIC Fun.. Module it didn't stop. As it is running in the background process, i also tried running the program RSNAST00 by providing the necessary parameters but to no avail.

Please help me .

Thank You,
