How can i insert a calculate formula from the same column?
I´ve a column wich was insert by me from other column.
The first column has diferent types of margin (like MRG1, MRG2, MRG3) and different types of sales (like VB1, VB2, VB3). I added a column with just Margin and sales. And know when i make the power pivot i see in a column the sales and in the other the margin. How can i make other column with de % Margin??
