Overview

Purging permits the user to purge selected records from the database.

It is highly recommended that you back up your database prior to purging operations, as there no way to restore purged requests. It's also recommended that no-one be using the system during a purging operation in case this causes the database to be modified after the point of last backup. If you purge the wrong item, you can immediately restore the backup without losing any data.

Life Cycle of an End User

1. Import from AD.
2. End User is used in Requests.
3. End User no longer in organisation, disabled in system.
4. Purging is done from time to time. The End User cannot be purged if it is still associated with a Request.
5. Finally no Requests are left to which the End User is associated.
6. Purging removes the End User.

The rule is that if an End User has been specified in the End User field in a Request, you can't purge or delete it. This is because there is a relationship between the data in the End User and Request tables. So purging will only delete End Users that don't appear in Requests.
