Question - How does Pull-in Push-out days affect MRP?
Answer - Pull-in/Push-out uses the order policy, demand due date, demand quantity, minimum order qty, and safety stock to determine if an existing order needs to be rescheduled and/or have the qty adjusted when the demand date changes. It does not allow for grouping orders outside the order policy setting, or produce more than is needed for a specific demand (over the min order quantities or safety stock).
For example: If the order policy is set to daily, and the existing work order is setup to meet a monthly demand, the user will get an action message to adjust the work order according to a daily grouping of the demand (reduce the existing wo qty and create new wo(s) as needed). In the same scenario, if the order policy was changed to monthly, then the single work order should not be affected.
If the user wants to maintain an order policy that is NOT consistent with their desired grouping, they must either firm plan the order, or create a separate Work Order for each demand grouping. The latter would result in multiple Work Order’s due on the same day with a qty set for each demand’s required qty rather than one Work Order on that day for the total demand.
