It's not clear here whether scenario parameter will be shown as a combo-box in a dashboard, or whether it's run directly as a cube view from OnePlace and thus prompts for the parameter value. It's also not clear what the POV setting is on the cube view, whether that is supposed to refer to the scenario driven from the parameter, or driven from the User POV setting.
I am guessing here that maybe the use-case is to have a parameter selection that specifies a *comparative* scenario, so the Cube View displays the scenario on the Cube POV (e.g Actual) but the DynamicCalc is supposed to compare the current POV scenario with the selected scenario driven from the parameter. If that is the case, then you will need to display the comparative scenario (from the parameter) in the cube view, either as columns or rows, and then use Cube View math functions to display the data for both scenarios, or show variance etc.
