About report parameters
Report parameters provide a mechanism for collecting values from a report user or a program. You typically use report parameters in filters to collect information that determines the data to display in a report.
In BIRT Studio, you can create a static filter parameter or a dynamic filter parameter at the data set level, or at the report table level. You can typically create static or dynamic parameters at the data set level for reports using templates with data sets, as well as information objects or data objects.
To construct a filter parameter, complete the following tasks:
Choose a filter parameter type.
Define a condition.
Specify whether the parameter is required or optional. Dynamic filter parameters are always optional.
Specify a display type.
Specify a list of values from which a user can select values. You can specify a static list, or a dynamic list. You can create a dynamic list of values at the data set level, or at the current column level.
