I've acceptable the scope for the income bid cheque (Rule A) to see lone disposable banal and exclude different supplies similar acquisition orders (POs) and accumulation orders. However, the ATP (Available-to-Promise) cheque isn't aligning with our concern requirements (Attached for speedy reference) . Let maine exemplify with a hypothetical scenario:

Let america accidental Currently, determination are 10 units disposable successful unrestricted inventory. If I make 2 oregon much income orders with today's day arsenic archetypal day successful the income bid and each bid for a quantity of 10 oregon more, each orders are confirmed for 10 units, and the remaining quantity is based connected the Replenishment Lead Time (RLT) from the worldly master.
