Set the Report Size Limit for the Report Data Service
You can increase the size limit for report data.
To limit the resources, such as memory, that are used by Report data service, IBM® Cognos® software restricts the size of the report data that can be sent out. If you receive errors in IBM Cognos for Microsoft Office that a report result is too large, you can increase the size limit for report data by changing the Governor limit setting.
The maximum execution time setting has priority over this setting. For more information, see Setting the maximum execution time.
