What is a Parameter? A parameter consists of the following: Element description Prompt • Appears as the title of the parameter when running the report. You configure this prompt to explain to the report user what the intention of the parameter is. It should clearly convey the values the user needs to enter. • A prompt is required for Optional and Required parameters. For more information on parameter usage, see Types of Parameters. • The maximum size for a prompt is 128 characters. • Sample prompts: Choose the start and end date for the data in your report. Enter the names of all domains you want to include. Field • The field that will be queried by the parameter. • Within a report, you can set as many parameters as you need to get the information you are looking for. You can create multiple parameters for the same field. • For more information on choosing the fields to include in your report, see Modifying the Fields to be Included. Condition Operator • Sets the basis for the conditions that will be set to filter the available data. • The operators available vary depending on the field. For a list of operators, see Parameter Operators. • Examples of operators: Includes, Equals, Between. Default Value • These values are presented when the report is run, and the user can choose to run the report using the default values, or to change the values to anything they want. • For Optional and Required parameter types, you can choose to create a default value, or list of values, depending on the operator. • Default values are required for Hidden parameters. • The form of these values is determined by the field and operator. For example, a date takes the form dd/mm/yyyy. Some operators allow you to create lists or ranges. You must enter values in the correct form before you can finish creating the parameter.
