Hi Rachel,
Check if due to some reason these orders are not "Output fix" or falls any of the definition of fixed orders.
1. CTM considers orders which are not inside the planning horizon as fixed. An order is considered fixed if the start date is before the planning start date or if the end date is after the planning end date. Orders that are lying inside the planning horizon and have been pegged to orders or demands outside the planning horizon are considered fixed.
This effect is amplified when you use dynamic pegging.
2. CTM does not delete any planned orders within the production horizon. These orders are considered fixed. The horizon starts on the system date (or the date you specified as the planning start in the CTM profile).
3. Orders which have at least one component that does not belong to the master data selection of the CTM profile are considered fixed.
