Hello Allie Malvaso,
i had the same issue where in the Production Order Backflush indicator was not set where as in the Material Master MRP 2 view Backflush was set to "Always Backflush".
Issue was with the Storage location.
In my Production Order this material was set for the Storage location "4000" and 4000 storage location was defined as "General Warehouse". During the SAP implementation there was a rule defined that when the storage location is set as 4000 there will not be any back flush.
Changing the storage location to any other location solved this issue.
