How can I validate Global Trade Item Numbers (GTIN) ?

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.
