When performing some changes under Xray, Jira will suggest you to perform a re-index. Then when is really needed to make this re-index?
So here is a list of the Xray actions that will always need to perform a re-index after changes in Xray's configurations under Jira Administration:
- Custom Fields
- Issue type mapping
- Requirement Coverage
- Manage Test Statuses, if the option Final over non-final is changed
- Integrity checker if you perform any Clear option under "Calculated Custom Field Values"
Any other actions will not need to perform a re-index.
