Copy Column Transformation in SSIS

Copy Column Transformation in SSIS duplicates the source columns. Just like copying the column data and pasting the data into a new column. It is a significant transformation because if we want to perform multiple operations on a single column, then we can create multiple copies. And later, we can perform one action on one copy.

For example, we have a column name product price, and we want to calculate dealer price, distributor price, price including VAT, and price plus wastage cost. Now we create duplicate columns for the above requirements using SSIS Copy Column Transformation. And then, we will calculate dealer, distributor, VAT, etc., prices individually.
