APO PPDS - interactive change of shelf life in planned order
I am working on a following issue regarding shelf life in planned orders in APO PPDS. The requirement is to be able to change interactively (manually) the shelf life date in planned orders.
Normally the shelf life data is maintained in product master data where from the system gets the shelf life into planned order when creating one.
In this example the production does produce much earlier before the requirement day and puts the produced quantities into storage location under certain minus temperature. Therefore they want to change the shelf life days in planned orders interactively, otherwise the system would get e.g. 50 days shelf life for the planned order as maintained in product master. I know that we have the option in production orders in SAP PP-PI. But I could not find by now any possibility for planned orders in APO PPDS.
Could anyone help? Is there any heuristic / algorithm or user exit that would allow to change the shelf life day in planned order in APO PPDS?
Thank you very much for any input.
