You plan using lot-for-lot order quantity, when you want to procure the exact lot size again.

This procedure is also referred to as the lot-for-lot procedure.

You have set the indicator EX for lot-for-lot order quantity in the Lot size field in the material master (MRP 1 view) for the material.

When planning using lot-for-lot order quantity, the system uses the exact shortage quantity (requirement minus available stock) as the order quantity in the case of a material shortage. At the time of the requirements date, the planned plant stock is zero.

Planning is carried out daily. The system groups requirement quantities from the same day together in one procurement proposal.
