Use
Use this function to check whether material components in networks are available on the requirements date. If the requirements are not covered on the requirements date, the system determines the date on which they can be covered.
Prerequisites
Since purchase order and purchase requisitions are irrelevant to internally produced materials, you can assign such materials to checking groups whose check scope does not include these MRP elements.
If no checking group has been entered for a material, the system does not check its availability. In this case, the system makes a corresponding entry in the material availability log.
Features
The system only checks those components that have
item category L (stock item)that are not procured directly..The following are not checked:
In the R/3 System availability is determined according to the (available-to-promise) ATP method. In this process, the system checks:
The availability can be checked at the plant or storage location level. The level at which it is checked depends on the following:
If availability is checked at storage location level and the component is available, the system also checks at plant level since other requirements at plant level could withdrawn material from the storage location.
If the requirements refer to a sales order item or a WBS element, the system always checks the relevant
segment of the sales order stock or project stock.Activities
You can trigger availability checks manually or let the system trigger them automatically.
More information on material availability checks is in the Requirements Planning (PP-MRP) component.
