Elaborate a plan in line with your business rules, current regulations and your performance goals.
Available to Promise or ATP stock refers to the amount of resources actually available when a new order is received.
A company's business planning consists of different stages, each of which is used to determine whether the resources will be able to meet sales forecasts and / or firm orders from customers.
ATP calculation occurs at the level of the Production Master Plan.
In fact, during this stage, the sales forecasts are the Input (incoming data) that will be used to define the quantities to be put into production.
The Available-To-Promise stock is therefore based on quantity put into production minus the number of firm orders by the customers. This then becomes a question of reserving the quantities in stock necessary to meet the demand and ensuring their placement into production.
