Hi Expert!

I set a Planning Time Fence of 10 days for Material "Z9980223.
The Sales Order has been created with a delivery date of 2025/01/24.

Subsequent MRP runs resulted in a Purchase requisition being created with a delivery date of 2025/2/5.
I believe the Purchase Requisition should be created on 2025/1/24.

Hi Soma,

The system behaves as design and it seems that you have a wrong understanding of the planning time fence.

In SSCUI 101171 - Check MRP Types, you can check how the firming types work with the planning time fence:

  • 0
    Procurement proposals are not firmed automatically. No firming takes place with this firming type.
  • 1
    Procurement proposals within the planning time fence are firmed automatically as soon as their date is at least one day before the end date of the planning time fence. The date of new procurement proposals created in the planning time fence is moved to the end date of the planning time fence. As a result, these new procurement proposals are not firmed.
  • 2
    Procurement proposals within the planning time fence are firmed automatically as soon as their date is at least one day before the end date of the planning time fence. No new procurement proposals are created automatically within the planning time fence; that is, the shortage situation is not adjusted within the planning time fence.
  • 3
    Procurement proposals within the planning time fence are not firmed automatically. All procurement proposals required to cover the requirements are moved to the end of the planning time fence.
  • 4
    No procurement proposals are created automatically within the planning time fence; that is, the shortage situation is not adjusted within the planning time fence.

You are using MRP type P1, where firming type "1" is set. So the purchase requisition is moved to the end date of the planning time fence.

Best Regards
Matt
