Product Availability Check

Purpose

The product availability check is carried out based on the ATP quantity (Available-To-Promise). The ATP quantity is calculated from stock, planned receipts (production orders, purchase orders, planned orders and so on), and planned requirements (sales orders, deliveries, reservations and so on). The system dynamically checks stock and planned goods movements - either with or without using the checking horizon – according to the operation for this type of availability check.

Overview

When entering sales orders, you can only confirm the delivery of the goods on the delivery date if they are available for all processing activities preceding the delivery.

For shipping activities, this means that the shipping department or a different transportation firm must be contacted early enough to ensure an adequate amount of time for packing and loading. You can execute availability checks up until the time that the goods must be prepared for shipping.

For procurement activities, this means that production or sales must be promptly notified about insufficient stock in order to resolve the shortage (that is, so that the goods can be produced or ordered). Information about the required products is sent to transportation planning in the form of requirements. Requirements thereby represent planned issues. Production is informed that goods must be produced by this requirements notification. Sales is also perhaps notified that goods need to be purchased, which means that purchase orders must be created and sent to the suppliers.
