The properties allow generating cross-tab reports that do not have summary columns and rows more efficiently.
property AllowSummaryCols: Boolean;
property AllowSummaryRows: Boolean;
These properties are used only when building a cross-tab report. Otherwise, they are ignored.
You can assign AllowSummaryCols = False if the report table does not have functions in summary columns for this rule. You can assign AllowSummaryRows = False if the report table does not have functions in summary rows for this rule. These assignments allow building a report faster and using less memory.
