Example for Determination of Availability Date
If you use period lot sizing in MRP and set the availability date as the period start, the system determines the availability date from the delivery date and the goods receipt processing time. The system then reschedules the availability date to the start of the next period that lies after the calculated availability date.

The system displaces the availability dates for planned orders 1000 and 1001 to the start of the next period possible (1 October) which lies after the date (4 September) determined by forward scheduling.
The date 4 September results from forward scheduling from 12 August + 20 calendar days + 1 day for goods receipt processing time.
