Omit Element (RDL)
Indicates that the parameter is ignored when a user opens a report using a drillthrough link on another report.
The Omit element contains an expression that evaluates to a Boolean value.
When a user opens a report using a drillthrough action, and the Drillthrough element of the originating report contains parameters that contain an Omit element value of True, those parameters are skipped when the target report is run.
If the target report name (contained in the ReportName element within the Drillthrough element) is not an expression, Omit is not used.
