SIMG_CFMENUOPP2OPPD - Define Planning Time Fence and Roll Forward Period

In this step, you define the planning time fence and the roll forward period.

• Planning time fence

You use the planning time fence to define the period that the MRP result is to be protected from any automatic changes. In this period, depending on the firming type maintained in the MRP type, no order proposals are changed or created automatically. Thus, the MRP controller can the check the dates and capacities of the planned orders before the planning result has any efect on the lower-level BOM.

• Roll forward period

• To update the master plan automatically, you can set the system so that out-of-date and firmed planned orders that lie before the roll forward period are deleted during the planning run. With this function, the system deletes all the planned orders for which there are no longer any requirements.
  
  

Note on roll forward period

In the step, "Check MRP types", you can maitain the indicator, "Delete out-of-date planned orders" with which order proposals that lie before the roll forward period are deleted and new re-scheduled planned orders are created (or depending on the planning time fence, they are displaced to the end of the planning time fence).

1. Define the planning time fence per plant and MRP group.
2. Define the roll forward period.
