How is the Availability Determined?

The availability is determined according to the ATP method (available to promise). Using this method, the system checks:

Whether the material requirements can be covered on the requirements date

At what point in time the requirements can be covered if full coverage of the requirements is not possible on the requirements date

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.

Committing the entire quantity Order quantity: 100 pieces

	Requirements qty	ATP qty	Committed qty
Component A	200 pcs	300 pcs	200 pcs
Component B	100 pcs	40 pcs	40 pcs
Component C	50 pcs	200 pcs	50 pcs

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).

Confirming partial quantities Order quantity: 100 pieces

	Requirements qty	ATP qty	Committed qty
Component A	200 pcs	300 pcs	80 pcs(40% of 200)
Component B	100 pcs	40 pcs	40 pcs(40% of 100)
Component C	50 pcs	200 pcs	20 pcs(40% of 50)
