7.2.3  Acquiring a Parameter Value

The value of a parameter (variable) is assigned only at runtime, and can be acquired from various sources, as described below:

End-user prompting: By default, the end user is automatically prompted for parameters (variables) used in conditions. To manage user prompting, see Defining and Editing Report Parameters. To customize prompting, see Parameter Sheets.

Drill-down hyperlinks: Parameter values can be supplied from a drill-down hyperlink in a separate report (see Hyperlinks), or by a script-based hyperlink. (See showReplet and sendRequest in Report Scripting for details.)

Report scripts: Report script placed in the onLoad Handler or formula column can set parameter values by accessing the parameter array. See Accessing Report/Request Parameters in Report Scripting.

User session: A report can obtain an external parameter value from the SRPrincipal object associated with the user session. See Accessing the User Session with SRPrincipal in Integration for further details.

Scheduled task: A scheduled task can pass values to condition parameters at the time that it automatically executes a report. See Scheduler Actions for more details.
