> ## Clearing unconnected records

> The Clean Ups > Clear Unconnected Recs item on the administrator menu bar is only available to the administrator. Unconnected records are created when someone deletes a record while another user has locked an associated record in Read Write mode. For example, someone may delete a Subject record while one of the subject's Tumor_Description records was locked and thus could not be deleted. In this case, the Tumor record would no longer have a Subject record to connect with.

> This option must be used carefully if the data file includes records imported from participants in a multi-site clinical study. In this case, records may have been imported for the purposes of the study that are not connected to a Subject record in the data file. By default, this function will avoid deleting these unconnected records as long as the Participant IDs for the different study sites are all unique.

> After selecting Clear Unconnected Records, you can remove all unconnected records for:

> - This participant only
> - All participants
> Related topics
> Execute All Clean Ups menu item
> Assigning the Participant ID
> Unlocking forms
> Adding and removing a group of subjects
