Hi @PankajChaudhary,

to get the column sum for multiple columns you can use the Math Formula (Multi Column) node.

In the top part you can select the columns for which you want to calculate the column sum.
In the lower part you can define the mathematical operation you want to perform.
In your case you can use the expression COL_SUM($$CURRENT_COLUMN$$) and activate the checkbox Replace Selected columns.

Best
