ATP calculations can be used to verify whether an order can be filled within a specific time frame given other demands and currently scheduled supply orders. For example, during order entry, this lets you determine whether inventory will be available to meet a customer’s needs before you commit to a promise date.

The system calculates ATP for sales orders, as well as for material orders (MOs) and return material authorizations (RMAs), which are part of the Service/Support Management (SSM) module. Depending on the level you select when you define ATP processing for individual items or item-site combinations, the system can either warn you or prevent you from processing a confirmed order when ATP is insufficient.
