When you attempt to create a report from a report template in IBM Rational Software Architect Design Manager (RSA DM), they "Save" button is inactive, which means that you will not be able to create your report.
You are attempting to create the report in the Shared Reports folder. It is not possible to create reports inside the root of either the My Reports or Shared Reports directories.
Resolving the problem
Add a sub-directory to either My Reports or Shared Reports and then include the
report in that sub-directory.
