Purge Configuration dialog box

The data purge is configured through the Plant Applications Purge Configuration dialog box. There are three tabs that enable you to purge data:

Tables
Units (Event Based)
Variables (Time Based)

You can select tables or units or variables or a combination. When you select units or variables, the retention period and records per batch for certain tables cannot be edited on the Tables tab.

IMPORTANT: Before you start a data purge, you must stop the Plant Applications Manager service. When you stop this service, it will automatically stop all other services that must no be running during a data purge. For more information, see the topic Stop Plant Applications Manager in this help file.
