3559236 - Error "The refund can only be created with reference to an invoice" in SAP S/4HANA Cloud Public Edition

Encountering the error "The refund can only be created with reference to an invoice" when attempting to create a return order with reference to a sales order that enabled digital payment. 

SAP S/4HANA Cloud Public Edition

Considering the legal risks, it is not supported to create a return order referring to a sales order that enables digital payment. If a refund is processed by referring only to a sales order that enables digital payment, the preceding sales order process may be incomplete (for example, having only a sales order without a generated billing document).

Considering financial security and potential legal risks, it is recommended to refer to the subsequent billing document of the sales order when creating a return order.
