ReportNet Exception was encountered while building the cube

[jerkzzz]

I got a Exception when I ran a report. I check it in report studio, and it is valid. What can I do else?

I find the solution. Thank you.
1. Open the CQEConfig.xml file, located in the install_location\configuration directory, in your favorite text editor.
2. Change the value of crosstabDecimalPrecision from 7 to 2.
3. Restart the Cognos ReportNet service.
