In period lot-sizing procedures, the system groups several requirements within a time interval together to form a lot.
You can define the following periods:
days
weeks
months
periods of flexible length equal to posting periods
freely definable periods according to a planning calendar
The system can interpret the period start of the planning calendar as the availability date or as the delivery date.
Splitting and overlapping are also possible for all period lot-sizing procedures (see Lot Sizes with Splitting and Overlapping ).
The system sets the availability date for period lot-sizing procedures to the first requirements date of the period. However, you can also define that the availability date is at the beginning or end of the period .
