Purge Inactive Currency Rates (currency_rates_purge_job)

Module Name	currency_rates_purge_job
Description	Purge inactive currency rates
Functional Area	Foundation
Module Type	Admin - Ad hoc
Module Technology	Background Processing
Catalog ID	N/A
Wrapper Script	b8dwrap.ksh

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 currency rates records based on its purge criteria from system parameter settings. The currency rates purge months parameter in system options will hold the number of months after which an inactive exchange rate can be purged from the system. The inactive currency rates which are earlier than system options purge months are captured for deletion. 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 purge the records from currency rates 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.
