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 general ledger key mapping table based on its purge criteria from system parameter settings. The Retain Transaction Data Days parameter will determine how many days the Transaction Data History records should be kept in the system. 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 general ledger key mapping table. PARTITION_SQL.PURGE_INTERVAL_PARTITION is also called passing the target table name "TRAN_DATA_HISTORY" and 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). 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.

The decision to insert or not to insert the records into the history tables is based on the Archive Indicator and Archive Job Indicator from the Background Process Configuration table.

1. If both the Archive Indicator and Archive Job Indicator values are Y, then the data from the base tables are inserted into the history tables.

2. If both indicators are set to ‘N’, then the records are deleted from the base tables without inserting into the history tables.

Note:

For more information on how to configure this process for archiving, see the Merchandising Implementation Guide section titled "Background Process Configuration".
