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 item-parent-location history by diff and item-location history by diff tables based on its purge criteria from system parameter settings. The Item History Months parameter will determine old sales history differentiator data on a specified system set date. 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 records from sales history differentiator and item-parent-location history tables. 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.
