I am trying to get a calculation but only for some rows (category). The problem is that in calculate you divide columns and for some categories, an error is posted (divided by zero by example). I had tried to use a filter to apply only to some categories, but I can’t restore all the values (were filtered).
In my mind, the logic will work with an IF flow transform (that is not implemented as I know). Another option is to use JavaScript, and ask in the JavaScript transform for the category (if the IF could accept calculations…)
