REASON
The issue resides with the inherent security check which is in place for reports. This check looks for the workgroups that are in place for the user to see if they have access. When the workgroup is deleted and the access check cannot find it, then the information will not be displayed.

RESOLUTION
When using Report Designer:

  • The best solution for this is to copy the report through Report Designer and select the "Bypass security access" in the report. The information will then show. 

When using Cognos:

  • Starting with Changepoint 2014 SP2, an "unsecured" model can be used, which is the equivalent to "Bypass security access" in Report Designer.
  • Rather than using the "Time combined" query subject, that enforces workgroup access security, you can use the query subjects "project time" and "request time". These don't check workgroup security, but validate if you have access to the respective project or request.
