Nydia Neuss Posted March 24 Share Posted March 24 Hello, I would like to run a formula on many columns in my datamanager, without writing the formula for each column. Is it possible to achieve this goal in an smarter way? Thanks Want to know more? Link to comment Share on other sites More sharing options...

Alessandra Casale Posted March 27 Share Posted March 27 Hi! You can use the copy formula / paste formula command. There are 2 cases: If the formula involves one variable only (e.g. $”X”=$”X”+1) define the formula for column "X" right click on column "X" and click copy formula select all the other columns of interest (control + right click to select them one by one, shift + right click for multiple selection ) right click and paste formula If the formula involves two (or more) variables (e.g. $”Z1”=$”X1”+$”Y1”) the situation is a little more complex. Let suppose you have the following dataset and you want to evaluate Z_i as follows: Z_i = X_i + Y_i where i =1,2,3. Define the formula for Z1, thus $”Z1” = $”X1” + $Y1” right click on “Z1” and select copy select Z2 and Z3, right click and paste This allows you to achieve your goal. Please note, the column order is crucial: when you copy the formula ”Z1” = $”X1” + $Y1” you are implicitly assuming that you are copying a relation between columns (i.e. column7 = column1 + column4). When you paste the formula to Z2 (i.e. the column 8), Rulex Platform automatically shifts the formula by one column, resulting in column8= column2 + column5. Finally, I would like to highlight one more feature of copy / paste formula. Let us suppose you want to quickly define the following set of equations: Z1 = X1 + Y1 Z2 = X1 + Y2 Z3 = X1 + Y3 using the copy/paste command. Here the issue is that X1 remains the same across equations. To achieve your aim, you define the first equation as $”Z1” = $$”X1” + $”Y1” and then just copy and paste this formula. The double $$ ensures that the variable X1 remains the same while the others vary according to the rules listed above. 1 Want to know more?
