To determine which quantities are available for a requirement, the system calculates the cumulated available quantity by adding stocks and receipts and subtracting requirements on their respective dates, as follows:
If the cumulated available quantity up to the material availability date is greater than or equal to the requested quantity, the requirement is confirmed on time.
If the cumulated available quantity up to the material availability date is less than the requested quantity, available quantities from later dates are consumed as well. The requirement is confirmed on multiples dates as soon as the required quantities become available, for example:
Requested quantity: 50
Requested material availability date: Monday
