title: In cognos, could we avoid an optional prompt asking a value when its parameter is used in a data item in a query?
body: <p>Actually, I'm working in Cognos 10.1 report studio. In my report, I have two prompts, one is optional and another prompt is required. I've used both the prompt parameters inside the data item for some condition. So, the optional prompt has also turned to required. What should we do to avoid this?</p>
