The requirement type refers to the origin type, for example, goods receipt for purchase order (Type B) or goods issue to cost centers (Type K).
The criterion that groups together all checking rules for all application areas for a material.
In conjunction with the checking rule, the checking group defines the scope of the availability check for each business event, that is, which stocks, goods receipts, and goods issues are taken into account in the availability check, and whether replenishment lead time is checked.
A rule that defines how the availability check is performed.
The checking rule, in conjunction with the checking group, determines the scope of the availability check for every business operation; that is, which stocks, receipts, and issues are included in the availability check and whether the check is performed with or without the replenishment lead time.
I hope this will help you,
