I understand that MRP will create unfirm jobs based on demand/forecast. Say I then firm a job that is supposed to run at the end of the week for a quantity of 100.
Then say a new order for 200- comes in with a due date that an increase in the quantity of that could satisfy. But the job is now firm.
Is there anyway to get MRP to suggest a change to the quantity versus create a separate unfirm job which could easily end up requiring a separate setup and be very inefficient?
