Is the project is completely baselined?

You know that the project is baselined, but not sure whether it baselined it complete or not. In such case, how do we know whether it is complete or partial.

Use the following formula for flag field:
1. IIf([Baseline Start]=ProjDateValue("NA"),No,Yes)
2. Set the summary rollup option to 'AND'

If rolledup value is 'Yes' for the root task then it is completely baseline otherwise it is partially baselined.
