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 RMS forecast information tables based on passed Domain ID. By default, all domains are captured and considered for purging criteria. 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 their respective RMFCS forecast information tables. Data deletion is performed by partition truncation, table truncation or deletion by domain. The method of deletion is dependent on whether or not the table is partitioned. This program serves to delete data by domains so that they can re-loaded with new forecast information from a forecasting system such as Demand Forecasting.. 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.
