## Data Buffer Information dialog

This dialog appears when you click View > Data Buffer Information on the menu bar. It helps you to view the information of data buffer in the current report and its subreports (make sure the report is viewed successfully once at least). You can adjust the performance and footprint for the reports according to the data buffer information. See the dialog.

The following are details about options in the dialog:

Report List

Lists the current report and its subreports' instance names.

Template Resources

Displays the data containers and datasets of the report and its subreports.

Detailed Information (for data container)

- Total memory for
