Check the Dampener Quantity and Dampener Period on the Item card. It can stop BC to suggest from canceling the order.
Dampener Period: Specifies a period of time during which you do not want the planning system to propose to reschedule existing supply orders forward. The dampener period limits the number of insignificant rescheduling of existing supply to a later date if that new date is within the dampener period. The dampener period function is only initiated if the supply can be rescheduled to a later date and not if the supply can be rescheduled to an earlier date. Accordingly, if the suggested new supply date is after the dampener period, then the rescheduling suggestion is not blocked. This field is enabled if Reordering Police is set as Order or Lot-for-Lot.
If the lot accumulation period is less than the dampener period, then the dampener period is dynamically set to equal the lot accumulation period. This is not shown in the value that you enter in the Dampener Period field.
Dampener Quantity: Specifies a dampener quantity to block insignificant change suggestions for an existing supply if the quantity by which the supply would change is lower than the dampener quantity. If the suggested change in quantity is higher than the dampener quantity, then the suggestion is not blocked. If this field is empty, then the value in the Default Dampener Quantity field in the Manufacturing Setup window applies.
