How can I update the requirements specification version in my concept structure to the latest version?

The Requirements table has a Refresh icon for you to quickly update the version of the requirements specification you're seeing for the current concept.

When you click Refresh and replace the current version of the requirements specification with the newest version of the requirements specification, the mappings of the previous version carry over to the new version if they're not in conflict with the updated version mappings. If there are specific requirements that no longer exist in the new version then those are removed. When there are multiple versions of the same requirements specification for a concept the data mappings remain the same.
