3551634 - The open amount of the billing document doesn't consider the down payment in the sales contract item-SAP S/4HANA Cloud Public Edition

• After creating a billing document, the open amount in the output of the billing document does not consider the down payment in the contract item when the sales order has CB1 (drop-ship) item.
• However, when the same scenario is created with item category TAN (sell from stock) or CBAB (bought-in), the down payment gets considered while calculating the open amount in the billing.

1. Create a contract (order type CQ, Item category CKMN) and set down payment in item level.
2. Create a sales order with CB1 item category using the contract as reference.
3. Create billing document using the sales order as reference. 
4. Complete the item drop-ship process.
5. Perform the billing for the sales order item.
6. In the billing document, the open amount is not considering the down payment taken against the contract item.
7. However, if the same scenario is created with item category TAN (sell from stock) or CBAB (bought-in), the down payment gets considered while calculating the open amount in the billing.

The issue arises because down payment for contract items is only supported for delivery related processes like CBAB.

The process for CB1 is third-party processing where invoice is order related.

• To use down payment of the sales contract, delivery related item category, like CBAB, should be used in sales order.
• To use down payment in combination with third-party process, the item category DB1, which represents CB1 with down payments, can be used. Under these circumstances, the down payment in the sales contract cannot be used.
