A company uses Master Planning with a plan that has 'Firming' enabled. The planner wants to automatically firm planned purchase orders that are within a 10-day time fence from today. The plan is set up with a firming time fence of 10 days. After a master plan run, the planner notices that some planned purchase orders within the 10-day window were not automatically firmed. What is the most likely cause?
Automatic firming within the firming time fence is based on the planned order's requirement date. If the requirement date is beyond the 10-day window from today, the order will not be automatically firmed, even if it appears within the window based on other dates. The planner should verify the requirement dates of the unfirmed orders.
Why this answer
Automatic firming of planned orders within the firming time fence depends on the requirement date of each order. If a planned purchase order has a requirement date that falls outside the 10-day window from today, it will not be firmed automatically. The planner must check the requirement dates, not just the order creation date, to understand why some orders were not firmed.
Exam trap
The trap here is assuming that any planned order created within the time fence will be automatically firmed, when in fact the firming is based on the requirement date, which may differ from the order date.
