Product Id and Product Id Ext.

You can now use the same unique productID for two different products. Previously, a

unique productID was assigned to each product.

You can differentiate the two products by using the PRODUCTIDEXT characteristic.

Example:

Product 1: Value of productID is 'A' but has no PRODUCTIDEXT.

Product 2: Value of productID is 'A' and PRODUCTIDEXT is 1.
