Ordering
All orders shall be effected exclusively in written form. The organisational part of the order includes the SAP order number, delivery address and invoice address. Even in the case of making orders by phone, the SAP order number has to be stated. All this information has to be stated in the invoicing and payment documents. If this data is missing, the payment deadline of the invoice may be exceeded due to necessary time-consuming research.
