The forecast for each week of a four-week schedule is 50 units. The MPS rule is to schedule production if the projected on-hand inventory would be negative without it. Customer orders (committed) are as follows:

Week	Customer Order
1	52
2	35
3	20
4	12

Use a production lot size of 75 units and no beginning inventory. Determine the available-to-promise (ATP) quantities for each period.(Leave no cells blank - be certain to enter "0" wherever required.)
