ATP (Available-to-Promise)
Available-to-Promise
Quantity of uncommitted inventory or planned supply that can still be promised to customer orders.
Examples
- 01A customer asks for 300 valves next week; ATP shows 180 in stock not yet promised plus 200 in production, so the order can be confirmed.
- 02The monthly supply review compares ATP by product family with incoming orders to see where promises are getting tight.
- 03When ATP for a key product turns negative in week 14, sales, planning and production agree which orders are moved and inform the customers.
