Wrong. You're a PM. You of all people need access to the warehouse. You need read only access to query the warehouse only. Don't let them give you read/write. Nobody should write to the warehouse but the warehouse. Making changes in the warehouse would ruin the beauty of the warehouse - it gives you snapshots in time of your Team System metrics so even if something changed today you can go and see what state it was in yesterday or the day before, or the week before.
But they told me "The TFS warehouse is a production system and you have other ways you can access the information, like MS Project".
Nope - still wrong. Wrong times nine. What can you do with the warehouse that you can't with MS Project? Lots. Tons. All kinds of things.
- Use Team System as a time entry tool.
- Create dashboards for requirements, development and test that update automatically on a daily basis.
- Find out how many bugs are created each day and why - find issues in your process.
- Find out how many bug fix hours you're spending per development hour per project.
Another thing - don't let them give you access to the TFS database. That really is a production system.
