When an Automated Test Framework (ATF) Test is completed, the platform should rollback any record which has been created/deleted/updated. However there are times when the rollback does not happen.
This might occur when there is a record in the [sys_rollback_context] which is left in the 'In progress' (in_progress) or 'Currently rolling back reverting' (reverting). This prevents the platform from executing any other rollback.
The same script as the one mentioned in the Known Error Article KB0714289
can be used to fix the issue. You must confirm first that the rollback context currenty marked as running is not doing anything anymore.
