Parameter connections represent links between report widgets.
To create a parameter connection manually:
Click
Dashboard > Widget
Communication.
The Widget Communication dialog
box is displayed.
Expand a widget in the Widgets and Parameters pane to reveal its
parameters.
Drag a parameter to the
New Parameter Connection
field of the
Parameter Connections pane.
A parameter connection is created.
From each widget that you want to include in the connection, drag
a parameter of the same type and drop it on the parameter connection.
Note: A parameter connection can only contain one
parameter from each widget.
As required, drag further parameters to the
New Parameter Connection
field to create further parameter connections.
You can create a parameter connection with only one parameter but
this triggers a warning message. You should do this only while designing a
dashboard. Remove the connection, or add further parameters before making the
dashboard available to users.
By default, the values of the parameters in a connection are
stored in the dashboard and used each time the dashboard is opened. To turn off
storage, select a widget from the Initial Value list. The selected widget
becomes the leading widget.
