Is there a way to 'baseline' requirements in RRC?

Thanks, Wolfgang.

I can't find the 'Baselines' section in the sidebar. Where exactly should I be looking? My sidebar just has Create Requirement, Use Case Diagram, and Upload Artifact. Is that the right sidebar?

Also, I did check my roles, and I have Author, Commenter, Administrator, and Project Snapshot Administrator. The link you sent me says I need Project Baseline Administrator, but I assume that's the same as Project Snapshot Administrator?

From Version 3 to Version 4 terminology changed slightly. In Version 3 it was called a snapshot. In version4 it's called a baseline. So due to your terminolgy I assume you are using version 3. So in this case the link http://pic.dhe.ibm.com/infocenter/clmhelp/v3r0m1/index.jsp?topic=%2Fcom.ibm.rational.rrm.help.doc%2Ftopics%2Ft_create_snapshots.html applies.

"Thanks, Wolfgang. I can't find the 'Baselines' section in the sidebar. Where exactly should I be looking? My sidebar just has Create Requirement, Use Case Diagram, and Upload Artifact. Is that the right sidebar?"

No, there is a sidebar on the right. Possibly you first need to activate it. On the right of the browser there is a small indicator that allows you to expand the bar. Within that there is a section with the Snapshots.

Okay, I found it and created a baseline, then made some updates, and created another baseline. How do I compare the two baselines to see what changed?

The colletions comparison was a useful tool, but not answer the question which, also its mine question. The baseline comparison is so expected as colletions was, and the customers are claiming to. Are there plans to implement it?
