Responding to parameter field prompts
Previewing .a report for the first time
When you preview a report for the first time, the Enter Prompt Values dialog
box appears, prompting you for a value.
• If you specified a default value when you created the parameter field, the
program will use that value unless you specify a new one.
• If you did not specify a default value, the program will not refresh the data
until you supply a new value.
Note: If the parameter is a string value type, without a default value, and the
“Allow discrete values” field is True, an empty string appears.
Refreshing report data
When you refresh data from the Preview tab, the Refresh Report Data dialog
box appears.
Select the “Use current parameter values” option to use the current parameter
value.
Select the “Prompt for new parameter values” option to enter a new parameter
value. When you select this option and click OK, the Enter Prompt Values
dialog box appears.
• Enter String values exactly as they will appear in the field. If the parameter
field allows multiple values, you can enter additional parameter values
using the Add button.
