You can create and use design tables for Dymola behaviors as well as for stand-alone Modelica models. The creation and use is the same, but if you want to work with scenarios, they are different when it comes to what you have to do to prepare them.
For a scenario creating design tables for Dymola behaviors, see Functional & Logical Design Users Guide: Managing Behaviors in Functions and Logical Components: Working with Dymola Behaviors and Context Behaviors: Creating and Using Design Tables..
