When an EDI order is received, a particular requested line item may have been obsoleted.  Instead of asking the trading partner to send the order again with the correct item number, users may choose to edit the EDI order and replace it with the current active item.

This is typically achieve by delete the old line item and add a new line item. Since EDI order line item may contain attributes that's critical to go back to the trading partner. By deleting the old line item, those associated attributes and also deleted. On the other hand, those attributes are not added to the new line item.  This cause EDI operation problem when try to send ASN (Advanced Shipping Notice) or Invoice.

Therefore, it is proposed that we should have a feature to replace the line item's item number.  As a result, all attributes that was associate we the line  item will stay and the return EDI document like ASN and Invoice can continue to work.

To replace a line item, all related Quantity Allocated, ATP info should transfer from the old item to new item. The quantity, pricing, request and promise date should not change.
