As of Release 3.0C, the SAP system supports the POR (purchase order with reference) procedure in Switzerland which simplifies payment transactions with a payment order.
To carry out the POR procedure, you must first create an output record with output type RDES for all invoices due to be printed. To print, use form SDESRINV0I01. When issuing invoices, the system accesses table T049E which contains all information necessary for the POR procedure, such as participant number and POR variants, among others. When maintaining this table, keep in mind that you cannot have more than one active data record per company code.
