Design Overview
This background job is composed of two steps processing. It will have a threading assignment and a business logic processing.
Thread assignment program will filter eligible records from price history tables based on its purge criteria from system parameter settings which is Price History Retention Days. These records are chunked and Thread ID is assigned for each. They will be stored temporarily in a staging table.
The Business logic program will process all records from the staging table. Using bulk processing, this program will delete the old/aged records from price history table and keep only the most recent records for the item/location/transaction type combinations. It will free up and clean the staging table afterwards. There is a STOP ON NEXT feature in bulk processing (through a loop) where Administrators can stop this batch with a flip of this indicator.
Note:
This process also supports archiving, if desired. For more information on how to configure this process for archiving, see the Merchandising Implementation Guide section titled "Background Configuration Process".
