Strategy: Example
If you use this strategy, the availability checks uses ATP logic according to the priorities you define.
100% Availability
Gross requirements: 100 pieces
Calculating issue quantity for 100% availability

The required quantity of the first material in order of priority that covers 100% of requirements is reserved (material B).
The system sets the usage probability of the reserved material to 100%. The quantity and usage probability of the other alternative items (materials A and C) are set to 0.
Missing Parts Situation
When none of the alternative items cover the requirement 100% on the requirements date, the availability check confirms a 0 quantity for all the items. This means that there is no reservation.
