Choosing a parameter type
A static filter parameter is a filter condition that the report developer defines, that prompts the user to specify one or more values when running a report. The filter condition typically consists of an operator, specified by the report developer, and corresponding values, to be specified by the report user when running a report.
A dynamic filter parameter differs from a static filter parameter in one important aspect. Using a dynamic parameter, the report developer can provide report users with a list of operators to use to construct a filter condition. The user selects an operator, then specifies one or more corresponding values when running the report. The report displays data for the filter parameter condition the user specifies.
