Issue Summary

Sprint-related reports do not keep historical if the statuses are no longer available. This means that if the status is removed from the board by unmapping it or if the workflow changes, it will impact the commitment and complete information in the reports.

Steps to Reproduce

1. Get a completed Sprint where the Velocity Chart has a commitment and completed data;
2. Edit the project workflow to use only different statuses and map them on the board.
3. Check the Velocity Chart.

**Similar impact can be seen also on the Sprint report.

Expected Results

The report should keep historical information.

Actual Results

The commitment and completion will change.

Workaround

As a workaround, in the new workflow we must ensure that all the previous statuses are included, but without transitions to it. This will allow the report to use the status data for historical purposes while will prevent users to accidentally transition issues to unused status.
