An Availability check is carried out during sales order processing.

An availability check occurs if-
 

• The Material requires an availability check-in material master (Gen./Plant or MRP 3)
• The Material availability checks in customizing-Delivery item Categories and Schedule line categories.

In Customizing, you can configure which inward and outward movements are to be considered in availability check.

Communication between sales and distribution and Procurement is carried out via requirements. The transfer of requirements type can be influence the availability check.

Any agreements made with customer about deliveries also affect the result of the availability check. Example-complete/partial deliveries.

The indicator for controlling complete/partial deliveries is proposed from the customer master records. The proposal for the item level comes from the customer-material information record, if a customer and material agreement maintained there. These indicators can be changed manually during order entry.

The availability check includes-

• Current stock
• Inward movement
• Outward movement
