Global Trade Item Number (GTIN) Relationships

You can create a relationship between an internal item and a Global Trade Item Number (GTIN).

When creating a GTIN Relationship, you must specify the Unit of Measure (UOM), and specify whether you're linking to a new GTIN or an existing GTIN.

You can associate the same GTIN with more than one item when the GTIN UOM and the item's primary UOM are the same. For example, when two or more items vary only by labels, you may want to use the same GTIN for those items. In such cases, you can create item relationships by associating the same GTIN to those items. To do this, you must enable the Allow Multiple Item Relationships to Same GTIN profile option in the Manage Administrator Profile Values task in the Setup and Maintenance work area.

You can use item rules to validate GTIN numbers:

• You can access the attributes of a GTIN relationship row (such as GTIN, UOM, or Party Type) by using the attribute group [GTIN].[GTIN Main]. This attribute group is available to rule sets associated with an item class.
• You can define item rules using the functions exists() and isNull() to validate the presence of GTIN values.
• You can define item rules using the function substring() to validate the formation of GTIN values.
