The Loyalty Codes are stored in the file LoyCodes.DAT and are used to group Inventory items for use with Loyalty Rules. Loyalty Codes are optional because Loyalty Rules can be based on other inventory item fields available for selection from the ID By button's Lookup List on the Loyalty Rule Setup screen. The Loyalty Buckets file LoyBckts.DAT is used to organize and identify the Rules that work together and to track Points separately for different Rule sets. Both the LoyCodes.DAT and LoyBckts.DAT files are always located in the same folder as the Customer Database file.
