What does Discrete ATP rely on to assess promise capability?

• A. Historical order fulfillment data
• B. Only the current period’s MPS receipt
• C. All available inventory including future receipts
• D. Overall market demand trends

Answer: (B)

Discrete ATP (Available-to-Promise) specifically assesses a company's ability to fulfill customer orders based on the current inventory and the current period’s Master Production Schedule (MPS) receipts. This means that the calculation is focused on immediate resources available to satisfy orders rather than considering past order fulfillment data, future inventory receipts, or broad market demand trends. The current period's MPS receipts reflect the most up-to-date production items that are expected to be available for allocation to customer orders.

By utilizing only the current MPS receipts, Discrete ATP provides a precise capacity assessment at that particular moment, allowing businesses to promise delivery dates reliably based on what is immediately available to them. This approach is essential in fast-paced environments where inventory levels and production capabilities can change rapidly.
