A
parameter is a variable whose value can be changed and that can be referenced by other report
objects. The SAS Visual Analytics Designer (the designer) supports
parameters for controls in reports. If a control has an associated parameter, then when the
value of the control changes, the parameter is assigned that changed
value. When the value of the parameter changes, any report objects that reference
the parameter detect the change accordingly.
Whenever a
parameter value is updated, then all display rules,
ranks, calculations, and filters that use that parameter are updated. Any report object
in the report that uses the display rule,
rank, calculation, or filter is updated accordingly.
For an example
of how parameters can be used in a complex report, see Example: Using Parameters in a Report.
