We have a Logical/Physical model with a table containing 50 columns. Is there a way to just change just the logical attribute order, and then have the physical column order automatically reflect that change?
That is a two-step process: after making the attribute order change in the logical model, you then need to go to the Physical model. From the Column Properties Editor, from the toolbar, select the Reset Order icon and then choose "Reset Order to Match Attribute Order". Press close to save your change.
