WBS Phase Anaylsis

I am working on implementing WBS phases into our Project IDs. I am running into some difficulties I could use some help with.

  1. Can you link more than one order release to a WBS phase?
  2. I have linked my jobs and Order releases to the WBS phase. Why is the system preventing me from running the WBS phase analysis?
  3. Is there a way to run the Cost analysis for all phases at once?

For point #1 - suggest to add that many milestones and add order releases to them, note 1 milestone = 1 release
For point#2 - what kind of error, it should allow - check the company parameters
For point#3 - how you running it currently … tell me the steps
