Inbound DESADV doesn't pack inbound delivery

I'm using in inbound IDOC (basic type DESADV01 / message type DESADV) to create Inbound deliveries. This IDOC contains packing information in segment(s) E1EDP08. This packing information however is not processed; the resulting inbound delivery is not packed.

In the partner profile I used process code DESA to process the IDOC. This process code is linked to Function Module 'IDOC_INPUT_DESADV'. If I look in this FM all code regarding segment E1EDP08 is commented. That must be the reason why the inbound delivery is not packed. Does anybody know if there is any other standard SAP functionality to create inbound deliveries that are packed.

Kind regards, Dick.
