You can use the Global Runtime Prompt Variables dialog box to select one or more global runtime prompts to associate with a business rule. This enables users to see the global runtime prompts when they validate or launch the rule, though the runtime prompt may or may not be used in the business rule.
To associate global runtime prompt variables with a business rule, in the Global Runtime Prompt Variables dialog box, select the runtime prompts you want to associate with the business rule. Use Shift + click to select multiple continuous runtime prompts; use Ctrl + click to select multiple non-continuous runtime prompts. Then click OK.
