What is Planning Time Fence?
Planning time fence (PTF) is a period which we define in number of days in the MRP1 view of material masterIt is a period which we can set so that the consequent MRP runs do not affect the plan which falls within the PTF.
The planning time fence is maintained in workdays.
Note: It is only used for materials that are planned using an MRP type which includes a firming type.
The firming type determines how order proposlas are to be created or scheduled within the planning time fence.
