Applying PO Specific prepayments using AP invoice Import.

Scenario: Milestone POs

• We are in the business where our suppliers actually build an engineering item for us. We would create a PO for this item.
• We pay 30 % upfront, another 20 % when they are half done and the balance when goods are received and final invoice is delivered. We are using standard PO functionaly and not the Buyer workbench with Service contract PO's
• We will have multiple PO's with the same supplier so the Prepayments of 30 % and 20 % are tracked at a PO level not at a supplier level.

1. So suppose i have 2 different PO"s for this supplier
2. PO A  - Value p $100
