Thanks Ada.
About the fixed and variable duration, this master data comes directly from ECC via our standard CIF designs and IM models. We don't have currently user exit for CIF. However, the requirement now is to overwrite these duration wherein data will be uploaded directly in APO. My question now is, what CIF user exit can we use such that the duration will be referred from APO and NOT from ECC? What are the important APO PPM tables that we need to check to achieve this overwriting. Also, the case is that not all PPMs' duration need to be referred from APO, there are some that will still be coming from ECC. I'm thinking of controlling this via custom tables too, is this doable? What are other things that we need to consider? We are using APO version 5.1 by the way. Thank you for the help!
Also, all rest of the PPM master data will still be coming from ECC.
Regards,
AA
