Contract start and end date in BAPI_CONTRACT_CREATEFROMDATA
I am using BAPI_CONTRACT_CREATEFROMDATA to create a contract from within a custom ABAP program. However I cannot figure out how to get the contract start and end dates into the contract header. I know that you can enter them into the ONTRACT_DATA_IN table parameter but these dates only appear on the line items and not the header.
Does anyone know which parameters on the function map to the contract header start and end dates.
