Availability Check for Components in the Planned Order 
Use
You can check whether the quantity available for components in the planned order is sufficient to produce the planned order quantity on time.
Features
The system checks availability for planned orders only on request, that is, the planning run does not automatically check availability.
You can carry out the availability check
- for a single planned order
- as a Collective Availability Check for a selection of planned orders.
You can choose between two types of availability check:
- Availability Check According to ATP Logic
- Availability Check Against Planned Independent Requirements.
You can see the type of availability check that was last carried out in the header of the planned order in the field entitled, Type of AvC.
You can carry out the availability check as often as you want with the following limitations:
- If you check according to ATP logic, you can repeat this check as often as you want. However, you cannot then check against planned independent requirements immediately afterwards. If you want to check against planned independent requirements after having first checked with ATP logic, you must first reset the check with ATP logic.
- If you check against planned independent requirements, you can repeat this check as often as you want. In this case, you can also directly change to the check according to ATP logic. Therefore, you do not have to reset the results of the availability check first.

You can switch off the availability check for certain materials. This is especially useful for materials that you know are always available in stock, such as screws. To make sure that these materials are not included in the check, you can set the indicator No check in the material master (view MRP 3) in the field Availability check.
