Inbound Sales Order via IDOC

We run SAP’s AFS (Apparel and Footwear Solution), which assigns a unique UPC to each size of a material.   If an inbound IDoc contains multiple UPCs that relate to a single material, standard SAP combines them into a single item in the sales order. We would instead like to have each UPC create its own item in the order (we realize this will cause the material to be duplicated).   Please let me know how this can be done.

Current Outcome

IDoc with two UPCs (773399 & 112233) that relate to a single material (12345678)

Sales Order:

Item 10             Material 12345678

Sch Ln 01         UPC 773399

Sch Ln 02         UPC 112233

Desired Outcome

IDoc with two UPCs (773399 & 112233) that relate to a single material (12345678)

Sales Order:

Item 10             Material 12345678

Sch Ln 01         UPC 773399

Item 20             Material 12345678

Sch Ln 01         UPC 112233

Please let me know if I can clarify our goals in any way.

Thanks,

Dan
