IDOC: Item text issue

Hi gurus,

Here's the scenario:

I created a sales order (VA01) in Box A and automatically passes via IDOC to Box B. From there, I created Delivery (VL01) and Shipment (VT01). Then the 2 document will be copied back via IDOC. So in Box A, it has already Delivery and Shipment.

The problem is, The delivery item text that I am getting is from the component of a BOM Material. I was thinking if I am getting the IDOCS from a sales order and not from the delivery doc. Since the materials in the delivery doc are not expanded..

How will I get the IDOCS from the delivery instead from sales order.

Point will be given...Thanks guys!
