Question to Z_ME_PROCESS_PO_CUST with item catagory L

Hi,

i have an PO with a position wich has an item catagory L = Subcontracting.

In this Position i have 3 Comonents (Object list).

I try to handle this Components in Badi: Z_ME_PROCESS_PO_CUST. I try to find this components in

method IF_EX_ME_PROCESS_PO_CUST_{PROCESS_ITEM and IF_EX_ME_PROCESS_PO_CUST}PROCESS_SCHEDULE

but didn't find any componets.

Has anyone an idea or it there another BADI or Exit to get this Components?

Thanks.

regards, Dieter
