Bulk Deleting
Availability
Unfortunately, bulk delete functionality is not currently available in the Rally tool. This is a popular feature request, so please see the link in the Head's Up section to add your vote. The more votes a request receives, the more visibility it gains among our Product Owners.
Workarounds
There are a few methods available to delete multiple records at once in a Rally subscription. Please note that these are suggestions from our customer base, and are not officially supported. One should have technical resources in place capable of troubleshooting these solutions, prior to undertaking them.
WSAPI
Many objects can be deleted through commands to our web services API. You may build a small script that queries and deletes the artifacts of your choosing. For a listing of available commands, and the proper syntax to use, please see our WSAPI documentation. Iteration and release objects cannot be deleted via the WSAPI.
Testing Software
One customer has found that UI testing software can be programmed to remember the correct click sequence to delete an object in the Rally tool, and repeat those actions multiple times. This is an option to delete hundreds of objects. The software suggested by our customer was SilkPerformer.
With both of these options, please exercise caution. Deletions via the WSAPI will be permanent (bypassing the recycle bin), and deletions of iteration or release objects cannot be undone.
