As of Release 4.0A, you have the option of using different
calculation schemas when setting up the price determination process
for External Services Management.
This is done in dependence on the document type. It should be noted that one particular calculation schema must be chosen per document type for universal use in the documents RFQ/quotation, requisition, and purchase order.
RFQ/quotation with document type AN, requisition and purchase order with document type NB must have the same calculation schema because document type NB is defined in Customizing as the allowed follow-on document type for document type AN.
You make the settings under
Maintain conditions for external services.
