Hi Carlos
On transaction OMDQ you will find the MRP type customizing and here there is a setting called "Firming type". System behavior will follow the setting defined for the firming type on customizing.
See the information provided on the F1 help of this customizing settings:
For the planning run, the firming type determines how procurement proposals are firmed and scheduled within the planning time fence. There are the following firming types:
- 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.
For MRP type P1, firming type 1 is defined, which means that it will firm existing orders within the time fence and new planned orders will be created outside the time fence.
