Given the following Master Schedule: Use production lot size of 100 units and no beginning inventory. Inventory is counted as physical inventory. Week 4 \& Week 8 no MPS is planned, it stays 0 . Determine the available to promise (ATP) quantities for each week. The ATP quantities can be presented to the Marketing Department to promise customers the number of units to be manufactured by a specific date. Week 4 \& Week 8 no MPS is planned, it stays 0. Formula: Week 1 ATP = Beginning Inventory + MPS - Customer Order Week 2 ATP = MPS - Customer Order
