Multilevel Available To Promise (MLATP) with Rules-Based Component Substitution
This article explains the process of Multilevel Available to Promise (MLATP)and component substitution in MLATP. MLATP is generally used in High Tech industries where final assembly is only initiated when a sales order is entered. The component availability check is done in the sales order and the bill of materials is exploded in the ATP check. The sales order line item is confirmed only when the components are available. The ATP check triggers creation of an ATP Tree structure and receipt elements are generated when ATP Tree structure is converted into a Production Planning and Detailed Scheduling (PPDS) planned order.
