3747131 - eDocument Poland: Empty KSeF Invoice for Down Payment Scenario

Unable to generate valid XML payload and application log during eDocument submission for Down payment Request created for Project Items, the XML is Empty.

SAP S/4HANA Cloud Public Edition

1. Create a Down Payment Request with reference to a Project Billing Plan for a Fixed-Price item.
2. Open the eDocument Cockpit App and search for the source document.
3. Observe that no application log or XML payload is generated and the eDocument remains empty.

In the Polish localization of S4HANA Public Cloud, the down payment process is supported only for Sales Orders and item categories such as `TAN`, `TAX`, and `TAD`. The down payment scenario in project business has not been localized. 

In the standard down payment scenario for project business, the system generates a down payment request rather than a down payment invoice. A down payment request is classified as a noted item, meaning it is a single-sided posting (commonly referred to as a `pro-memoria` item). Essentially, this serves as a reminder that a down payment is expected from the customer. However, since the down payment request is not an actual financial transaction, it cannot be submitted to tax authorities.
