Not reserve incoming puchase order quantity to SO during GATP

Hi,

We are using APO GATP - I have a customer requirement wherein, Purchase order & ASN should form part of the sales orders "scope of check" for visibility of delivery dates & quantities during sales order creation but the incoming Purchase order quantities shouldn't be reserved by the sales order. Currently, GATP during sales order creation looks at the incoming PO dates/ quantities and assigns the quantity to sales line item based on the future PO date/ quantity.

The customer requirement is to "ONLY" look at the PO delivery date & quantities but not assign them to any SO because we have a subsequent BOP (Backorder processing) run to assign all available quantities to open sales orders based on customer priority and order creation dates.

Thanks in advance for your help!
