   Purge criteria field value descriptions

   Field	Description
   Purge Code	Identifies a purge program. This is a system defined code.
   Description	Describes the type of purge.
   Rollback Segment	Defines the rollback segment that should be explicitly used for the purge transaction qualified by the purge code. This is useful when there are huge logical data sets that have to be purged. This is optional and used for order related purges.
   Retention Days	Enter the number of days the data is to be retained in the database (going backwards from the time the program runs). Make sure that your table size takes into account the number of retention days entered here.
   Write to Log File	Check this box if you want purged data written to a log file. The log file can be backed up and used as a journal at a later date.
   Log File Name	Enter a log file name. The log file is created in the directory specified in the yfs.purge.path property. If this is not passed, it defaults to the value specified in the yfs.properties file. If a variable is introduced, then the yfs.purge.path is ignored. To override this property, add an entry for it in the <INSTALL_DIR>/properties/customer_overrides.properties file.
   Additional Purge Criteria These parameters are used to override the order history purge retention days. This override is configured based on the line types within each order defined at the enterprise and document type levels. Note: These additional parameters can be defined only for order history purge (ORDHISTPRG) criteria.
   Line Type	Select the line types from the drop-down list.
   Additional Retention Days	Enter the additional number of days (apart from the retention days specified by the order history purge) the data is to be retained in the database. Make sure that your table size takes into account the number of retention days entered here. Note: To be considered for additional retention days, the order line must have at least some quantity that is not cancelled or shorted.

   Note: The history purge date cannot be reset when you restore the order after it was purged. For example, if an order is purged with a history purge date of 20070801 and when the order is restored in the year 2006, the history purge date still remains as 20070801.
