Using Roadway Characteristics Editor (RCE) during your everyday workflows, you may need to view and release locks. The locks table in RCE allows you to view and release route and event locks for advanced linear referencing systems (ALRS) with conflict prevention enabled. For more information about conflict prevention, see Conflict prevention. For example, you may want to add events to a group of routes in a new subdivision. Before you acquire locks, you could use the locks table to see if any locks exist on the routes where you want to add events. Once your editing is complete in the area, the locks table can be used to release any locks on routes without changes. The locks on the routes with edits would be released when changes from the version are posted to the lock root version.
The locks table can be opened from the Versioning group of the Review tab. Clicking the Locks button opens the locks table in RCE.
Locks table tools
The locks table can be used to view locks or release existing route and event locks with the buttons at the top of the toolbar. A lock or group of locks can be highlighted by selecting the lock records in the table.
The table is populated with 25 locks per page. To browse through the pages of locks, use the Next Page button 
, Last Page button 
, Previous Page button 
, First Page button 
, and the page number drop-down list.

Filters in the locks table
As Roads and Highways users complete everyday editing workflows, the locks table could have route and event locks from a variety of users, in different versions, on a variety of events, and on a variety of routes. To expedite the sorting of the locks in the table, filters are available based on the user, version, event, and route in which the locks were acquired. The filters can be used individually or in combination to only show the list of locks meeting those conditions. Filtering by user or version provides a drop-down list of all the different values present in the locks table. The event filter contains all the event layers in the map. To filter by route, paste the route ID of the route into the text box and press Enter, or type the beginning of the route ID. After three characters are typed, a list of matching route IDs appear that can be selected.
In the previous example, the user locked a group of routes to perform edits on a new subdivision of routes. Once editing is complete, the user wants to release the locks for the routes that were not edited. Table filters could be used to narrow the list of locks to those acquired by that user in the version used for editing.
