It happens from time to time that the product number of a product changes. Since we don't want to lose the history associated with the original product number, we do not allow product numbers to be changed on product records which are already linked to statement line items. To deal with changing product numbers, we instead allow a product number alias to be specified for a product. From that point on, any statement line item containing either the original product number or the product number alias, will automatically be be matched to the product record.

To get started, first go to Products:

Add a product number alias to an existing product record by clicking "None" and specifying the new product number for the product:

You can also modify an existing product number alias by clicking on an alias in the list:
