We have maintained routing process for few products.Based on operation timings during MRP run system proposing procurment proposals too early.
But user do not want this operational times for scheduling of planned orders , it requires for costing purpose only.
So i suggested to use BASIC DATE SCHEDULING in MD02 MRP run, so it will not considered routing data of the finished product , it only considers inhouse production time in material
But the problem is , when planned order is converted to production order system considering Routing data and proposing scheduling dates . Due to this planned order dates and producting order dates are different. when production order is created , dependent requirement dates of down level materials are changing.
So user want Routing for costing only not for scheduling .
I have tried this by using control key with only relavant for costing
not for scheduling and is assigned to each operation in routing
As control key is defined with no scheduling , production order start date and finish dates are same based on OPU3 settings whether it is FW
or BW scheduling
So pls suggest
