  Review Business Process: Ensure that the business process aligns with SAP's intended use of reservations. If down payments are necessary, consider using a different document type or process that allows for down payments.
  Use Alternative Document Types: Instead of using reservations, consider using sales orders or purchase orders, which can accommodate down payments.
  Check Configuration: Consult with your SAP configuration team to review the settings related to reservations and down payments. They may need to adjust the configuration if there is a valid business need to allow down payments in conjunction with reservations.
