You can use availability checks to make sure that the components you need to carry out the project/network are available when they are required. There is no point in conducting an availability check for the end-product alone, since this is basically the same as scheduling the network.

The Availability check and the Requirements transfer indicators have been set in the relevant requirements class.

You have allocated material components to activities in the standard network.

You have assigned checking groups to the material components (in the corresponding material master - MRP view).

During network scheduling the system sets requirements dates for the individual components. The availability of these components are then checked.

The system either confirms the requested delivery date, or if the network basic finish date is after the requested delivery date, it informs you so and requires you to confirm the later date.

The system scans the differences between the requirements date and the confirmed date. It then selects the largest difference and adds this time to the basic finish date of the network to produce the overall commitment date. The system then asks you to confirm this date in the sales document.
