Question about "Version" information in ETM artifacts
![](http://jazz.net/_images/myphoto/188b5931fb5906783450fdf0776f5e04.jpg)
In ETM, the artifacts like Test Plan, Test Case has Versions.
My findings are following:
- It is possible to compare a Version to another only if is part of a baseline
- It is NOT possible to compare any 2 version and find differences
- Version numbers are not part of history and hence it is not possible to find differences between 2 versions (unless part of baseline)
My questions are following:
- What is the intention of "Versions"?
- How could one find differences between any 2 versions?
- Why version info isn't part of history? or How can we relate version and change history ?
Thank you
