Purge revisions

Applies to User Roles:

System Administrator

Purge scripts help administrators with revision maintenance. The sc.revision.purge.hanging script purges all revisions that no longer have a parent record because the parent record was deleted or renamed. The sc.revision.purge script purges all revisions from the system.

There are two options available when purging revisions.

To search for revisions:

Purge All Revision Records removes all revisions from your system.
Purge Hanging Revisions removes only hanging revisions from your system. A hanging revision is a revision with no associated file or form. For example, if you create a form, create a revision of the form and then delete the original form, the revision remains on the system but with no associated file or form.

Note: You can restore a deleted form from its revision file.

Log in as a System Administrator.
Click System Administration > Base System Configuration > Miscellaneous > Purge Hanging Revision Records.
To remove hanging revisions from your system, click Purge Hanging Revisions Records.
To remove all revisions from your system, click Purge All Revision Records.
