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 department, class, subclass sales history tables based on its purge criteria from system parameter settings. The Item History Months parameter will determine record which is older than the specific number of retention months of fashion style history. 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 tables by department, class and subclass tables. It will also invoke a call to a new program specific for handling historical tables that are considered partitioned tables. PARTITION_SQL.PURGE_INTERVAL_PARTITION is called passing each target table names "ITEM_LOC_HIST", "ITEM_LOC_HIST_MTH", and "DAILY_SALES_DISCOUNT". This called program will execute the proper deletion/purging of records from target table by exercising table partitioning handling such as Dropping Interval Partition (same as truncate or delete from table). 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".
