I just deployed MS Lync monitoring into my environment.  All of the reports are working except for the "User Activity Report" under the Call Diagnostic Reports(per-user).  I am running a Windows 2008R2 server with a SQL 2008 db and a Lync Enterprise FE pool with a single enterprise edition.  All of the Lync patches and windows patches are up to date.  I know the Lync monitoring uses SQL Reporting Services which I have installed and is working for all of the other lync reports.  Any suggestions?

Hi

Do you get any error while Retrieving  "User Activity Report" 

I get the following error:

• An
  error occurred during client rendering.
  
  • An
    error has occurred during report processing. (rsProcessingAborted)
    
    • Query
      execution failed for dataset 'CallList'. (rsErrorExecutingCommand)
      
      • For
        more information about this error navigate to the report server on the local
        server machine, or enable remote errors

Hi,

Have you applied update for Lync Server recently? Here is a similar case for your reference. You can try to re-deploy Monitoring Server Reports.

Redeploying the monitoring server reports fixed the issue.  It is strange because I had no errors during either installation.
