The Customer Special Price file typically maintains an entry for every item that was ever purchased by every customer in the entrée system. This file can become very large because customers will typically change product brands. Or customers may stop purchasing a particular item all together. The special price file will have numerous records that are no longer needed.
The Purge Customer Item History utility provides a quick and easy means to remove the entries in the special price file that are outdated.
If one of the customers selected for purge processing serves as the "Special Price Customer" for other customer accounts, those linked customers will *NOT* be checked when establishing the "last sale date" for the customer/item combination.
