The availability is determined according to the ATP method (available to promise). Using this method, the system checks:
Committing Partial Quantities in Availability Checks
As a rule, the system tries to commit the entire requirements quantity of a component, providing the ATP quantity is sufficient.

If you want to ensure that the system only commits quantities that are needed in production, you can set up the commitment of partial quantities in Customizing (production scheduling profile).
In a partial commitment, only a percentage of the requirements quantity is committed. The committed quantity received by all components that are checked is determined by the component with the lowest relative committed quantity (commitment factor).
