Setting parameters for data objects

Dashboard designers use parameters to input values to a data object for filtering, formatting or processing data. When parameters exist in data objects, they appear on Select Data as parameter bindings. Launch Select Data by choosing Manage Data from the dashboard menu or adding a new data object to a dashboard.

Parameters can appear in the following ways:

n	One or more values that the user selects.

n	One or more fields where the user types values.

n	Cascading selections that present the user with choices based on other selections.

n	One or more conditional operators and corresponding values that the user selects.

Parameters in a data object affect data in all gadgets on the user’s dashboards. For example, specifying two cities in a data object’s parameter causes gadgets using that data object to only show data from the two selected cities. Each gadget can later apply additional filters.

BIRT report developers add parameters to data objects using BIRT Designer Professional and decide if the parameter value filters data or is used in a script in the data object.
