The SAP system will react differently to the planning time fence
depending on the MRP type selected. Here is the information that
explains the different type MRP types: (order proposals are planned
orders created by MRP to satisfy demands)
Firming type 0: Order proposals are not firmed automatically.
With this firming type, no actual firming takes place. The materials
only receive the indicator for MPS so that they can be planned using the
special planning run for master production scheduling. This firming type
only makes sense in combination with the MRP procedure MPS.
Firming type 1: An order proposal that lies within the planning time
fence is firmed automatically as soon as its date lies at least one day
before the finish date of the planning time fence. The date of new order
proposals that are actually created in the planning time fence are
rescheduled out to the end of the planning time fence. Therefore, these
new order proposals are not firmed.
Firming type 2: An order proposal that lies within the planning time
fence is automatically firmed as soon as its date lies at least one day
before the end of the planning time fence. The system does not create
any new order proposals within the planning time fence. That is, the
shortage situation is not adjusted within the planning time fence.
Firming type 3: Order proposals that lie within the planning time fence
are not firmed automatically. The order proposals required to cover the
requirements are moved to the end of the planning time fence.
Firming type 4: Within the planning time fence, the system creates no
order proposals automatically. That is, the shortage situation is not
adjusted within the planning time fence.
* Indicator: Planning time fence
Using the planning time fence, you can exclude a certain period from the
automatic planning run. In this period, only manual changes are made -
depending on the firming type. The system will not create any order
proposals within this period.
