3423766 - Partial clearing of down payment requests.

Upon posting a partial payment, the down payment request is cleared and becomes unavailable for selection to make any additional (remaining) payments. 

SAP S/4HANA Cloud Public Edition

1. Post a down payment request using "Manage Supplier Down Payment Requests" or "Manage Customer Down Payment Requests" app.
2. Try to post partial payments for the down payment request using "Post Incoming Payments", "Post Outgoing Payments", "Clear Incoming Payments", or "Clear Outgoing Payments" app.
3. The down payment request is marked as cleared even though it is partially cleared.

This is a standard system design. The down payment request will be cleared even though down payment amount is less than amount of down payment request.
The partial payment/residual item processing is not possible for down payment requests as it is for invoices.
