Currently in Jedox Web the subset editor can only be used to create - but NOT edit) subset formulas with the help of a graphical user interface.
After creating the subset it is not possible to edit/change the formula again via the subset editor.
It is only possible to apply changes in the formula itself by direct input,
which is a nightmare => to always remember the order and meaning of every parameter in those long formulas.
So re-loading a subset formula into the subset editor for applying changes would be very helpful.
Good point, Jens. In Excel, at least, it is possible select the subset that you want to edit and then that subset is shown in the subset editor. This same functionality should be available in Web!
By the way, I would avoid subsets in Web as much as possible, because dynaranges are more powerful. But indeed, editing an existing subset should be possible.
