The module replicates prices for business processes in ALE-scenarios.
Both table parameters ICOKL and ICOST serve to transfer data records specific to tables:COKL - CO-Object: Activity Type Control DataCOST - CO-Object: Sum Prices
The translation of the technical, period based field names in usual BAPI names is avoided in this case due to the clarity.
This BAPI is not intended for external use, but rather to implement SAP standard delivery ALE-Scenarios for business processes.
If you want to program in this BAPI, go by the definition of tables COKL and COST in the Dictionary (Transaktion SE11).
