Repairing Queries
You can repair queries that have been disabled. To repair a query, from the Disabled Queries view on the Collection Queries page, right-click the row of the query and select Repair.
* 
A query is disabled by the background if any references that the query contains are removed from the Windchill system. For example, a query is disabled if a folder that was selected in the query is deleted.
