Customer Exits: Valuation
To make it possible to valuate data in ways not supported by the system, SAP allows you to program your valuation routines using aCustomer-Exit.
You can maintain the customer exit using SAP standard enhancement COPA0002 in SAP Project Management. Call up Project Management from CO-PA Customizing using the function Tools® SAP Enhancements. There you will find the technical information needed to set up a user exit as well as an example.
For more information about valuation using customer-specific valuation routines, see the sections on valuation in CO-PA Customizing.
