In MD62 header screen we are selecting "w/o MRP" check box for entered forecast. So MRP doesn't consider forecast for planning. In this case FERT material is make-to-stock type. So if there is stock system confirms to the order else it create planned order in MRP.
Now per business if customer order is not within forecast (Example - Forecast is 10K for Jan-2016 and customer order is 15K then system shouldn't confirms it.
If customer order is part of forecast then it should check HALB stock. If HALB has enough stock then confirm otherwise not.
To me it doesn't make sense but just want to understand if anyone else has faced same kind of question.
Reply appreciated.
