Product allocation functionality allows you to manage the supply of scarce products to customers so that each customer receives an allocated amount.
Product allocation is incorporated into the sales order process as follows:
Step 1:
An order line item is entered for a material currently on allocation. This is determined by reading the material master and identifying that an allocation procedure is assigned.
Step 2:
An ATP (Available to promise ) check is then carried out to see if and when the requested quantity can be confirmed. An ATP check is not, however, a prerequisite for product allocation.
Step 3:
If the order quantity unit is different than the planning unit of measure, the order quantity will be automatically converted prior to the allocation validity. Secondly, if a conversion factor has been established to represent a constrained component, this factor will be used to calculate the proper allocation requested quantity prior to the allocation check against the planning data.
Step 4:
First, based upon the date in the allocation information structure activation rule, one of three dates (delivery date, material availability date, or planned goods issue date) from the sales order is used to validate the allocation quantity for the requested period. Secondly, depending upon the method selected and the allocation interval, quantities are accumulated and the future proposal dates are determined.
