2. This can be caused by a corrupt Report Server or ReportServer Temp database. This error can be resolved by creating a new Report Server and ReportServerTempDB by doing the following steps. Note in step 16 of this process, you will be attempting to run the report in CRM\BBDM to make sure it runs as well. There are several components to installing and configuring SSRS, which need to be completed first before attempting to deploy and load reports in CRM or BBDM.

See the following article for creating new Report Server and ReportServerTempDB databases:

See the following article for installing and configuring SSRS:

3. After making these changes above, re-ploy and load reports in CRM and then attempt to run the report and the error should be gone and the report will render.
