If the production- or process-related constraints permit, the system creates exactly one receipt in this lot-sizing procedure in order to cover a requirement that is not covered (for products produced in-house including assembly scrap). The desired availability date is the requirements date. To take production- or process-related constraints into account in lot formation, you can also plan with a minimum lot size, a maximum lot size and rounding. If the procurement quantity exceeds the maximum lot size, the system must create several receipts for the requirements date in order to cover the requirement.

To cover an uncovered requirement of 100 pieces the system must create a receipt with a purchase order quantity (external procurement) or with a yield (in-house production) of 100 pieces. For more examples see minimum lot size, maximum lot size and rounding.
