Generating reports in Bridge can be challenging. There are the default reports that are found on the Insights page in the form of Deep Dives. You can export users from the Manage Users section of the Admin page. But here is the rub. If you want to get just a list of terminated learners you must do a Download All Data from the Tools page and then parse the information found in the users.csv file. filtering out only those records that have a value in the deleted_at column. Doable but time consuming.
What I propose is using the existing filter found on the Manage Users page. When filtering out records you can select Terminated. Why not then be able to export data that just has the terminated records. Right now, regardless of the filter option selected you only get active learners.
