When you enter a delivery, the system carries out an availability check on the material availability date if the availability check is activated using the requirements class.

The following elements can be taken into account during an availability check in the delivery:

• Stock

• safety stock
• stock in transfer
• quality inspection
• blocked stock

• Inward/Outward movement of goods

• purchase orders
• purchase requisitions
• planned orders
• production orders
• reservations
• dependent reservationsdependent requirements
• sales requirements
• delivery requirements

The system determines the date on which the availability check should be carried out on the basis of the earliest material availability date of all the schedule lines in the delivery. If the system determines that insufficient stock will be available on that date, it responds as follows:

• If a material is not available for delivery by the material availability date, the system enters a delivery quantity of zero in the delivery. The item is only included in the delivery if the quantity zero is permitted for the item category.

• If the quantity available of a material is lower than the order quantity, the system enters the available quantity as the delivery quantity. If a partial delivery is not allowed for the sales order, the fact that the delivery quantity is smaller than the order quantity is noted in the log for the delivery.
