Best practices dictate that you only run an OLAP report at level 10 for one fund at a time. You can do so using the Submit with Override report option described in the troubleshooting section of the of Performance Analysis and Reporting User Guide.
When you run the report, remove all entities except for the one fund in question. Then edit the log level by selecting the Override the server log level check box and setting the log level to a value of 10. After the report runs, open the report results, select the Diagnostics tab, and click the Log File Name button to view the log.
