The agreements with the service vendors can be made into contracts in SAP and kept for reference during invoice verification in MIRO. Note that the contracts cannot be referred to in the service PO created from shipment costing.
Also, keep in mind the constraints of shipment costing:
- It is not possible to carry out shipment costing in the customer billing document depending upon transportation-specific data (for example, freight code, means of transport).
- You cannot settle shipment costs internally if a company code is performing shipments for another company code.
