Lot and Serial Control Items

Grade- and potency-controlled items must be lot-controlled. Use the Item Branch/Plant program (P41026) to identify an item as a lot- or serial-controlled item by entering one of these values in the Lot Process Type field:

Value	Description
Blank	Lot assignment is optional. Numbers must be manually assigned. Quantity can be greater than one.
1	Lot assignment is used. Numbers are assigned by the system using the system date in YYMMDD format. Quantity can be greater than one.
2	Lot assignment is used. Numbers are assigned in ascending sequence using next numbers. Quantity can be greater than one.
3	Lot assignment is required. Numbers must be manually assigned. Quantity can be greater than one.
4	Serial number assignment is optional except during shipment confirmation. Quantity must not exceed 1.
5	Serial number assignment is required. The system assigns numbers using the system date in YYMMDD format. Quantity must not exceed 1.
6	Serial number assignment is required. The system assigns numbers in ascending order using next numbers. Quantity must not exceed 1.
7	Serial number assignment is required. You must manually assign numbers. Quantity must not exceed 1.

When you attach a parts list to a work order header, the system creates commitments for the components. How these commitments are created depends on the parameters of commitment method, commitment control, and hard- or soft-commit. After you set up these parameters, commitments can be created in the same manner using both the Enter/Change Order (P48013) and Order Processing (R31410) programs.

When an item is defined as lot-controlled, the system moves the grade or potency range to the parts list and allows only those lots within the range to be eligible for commitments. Any remaining quantities are committed to the primary location.
