Reports retrieve data by running pre-built query objects. If a query needs a value at report run-time, it uses built-in, run-time parameters. At report run-time, the user is prompted to provide values for run-time parameters as a prerequisite for running the report. The report is then generated based on the user-provided values for those parameters.
Parameters are stored on the server, and therefore can be used in one or more report and query objects.
Note: We recommend designing all needed parameter objects before creating the query object that will use those parameter objects. (For information on creating queries, see Queries.)
