Types of Parameters There are three types of parameters that you can create. By paying careful attention to choosing the proper parameter type, you can ensure that you get the right balance of user interaction and preset information, and that your report serves its intended purpose. Each type of parameter has to have specific elements in order to be accepted. If you do not enter everything required for a particular type of parameter button, the OK button will be unavailable.
