Considerations for Selecting Lot Number Uniqueness Control

Use the Inventory Organization Parameters page to specify if lot numbers should be unique for an item.

Select one of these lot number uniqueness control options to apply to the items in your inventory organization:

• No uniqueness control

• Across items

When you perform transactions, Oracle Inventory Management checks the lot number uniqueness control to generate lot numbers.

No Uniqueness Control

Choose this option if you don't want to establish lot number uniqueness. When selected, you can assign the same lot number to multiple items in the same organization and across organizations. Organizations that choose No uniqueness control can enter any lot as long as the lot doesn't exist in any organization that's set to Across items.

Across Items

Choose this option to control lot number uniqueness across items. With this option, you can assign a specific lot number to only one item in the same organization and across organizations. The application verifies that the lot number doesn't exist for any other item in any other organization.

This table shows what's allowed:

Organization	Uniqueness Setting	Item	Lot Number
M3	No control	INV-101	LOT2
M3	No control	INV-102	LOT2
M4	No control	INV-103	LOT2
M5	No control	INV-104	LOT2

This table shows what's not allowed:

Organization	Uniqueness Setting	Item	Lot Number
M3	No control	INV-101	LOT1
M3	No control	INV-102	LOT1
M4	No control	INV-103	LOT1
M5	No control	INV-104	LOT1

It is important to understand that when you use this setting for an organization, the same lot number can't exist for any other item in any other organization. However, it's possible to have the same item with the same lot number in multiple organizations.

Note:

You can change the setting for the lot number uniqueness control at the inventory organization level if there are no open transactions.
