This determines whether the part number field in the ASCII product file will be used to determine the link to the item for the [item_link] tag. If set, this has the effect of creating a different HTML page link for every part number. If not set (the default), the [item_link] tag uses the value of the last field in the ASCII product file as the link value. This option is largely deprecated by the on-the-fly page building facility.
