Ansys Parametric doesn't make the loop

[Znjmech]

Hi All

I have a simple question , when I choose a variable in my structural model to make it parametric, in Workbench, I see that the arrow only exists from the step and goes to the parametric but doesn't return to the step, I just want to create a set of results varying the quantities of a variable in a range, witohut optimization. how is this possible to do ?
