Column Manipulation is a type of Data Transformation in which a new column is populated with values from an existing column, which meets certain criteria. The criteria can be an expression, which is created as part of the Data Transformation step.

Input Data

Let us consider the following input data, which represents the actual and forecasted sales figures.

October,7846,6354
November,6532,7451
December,4625,1424
January,8547,7852

Load Script

The above data is loaded to QlikView memory by using the script editor. Open the Script editor from the File menu or press Control+E. Choose the “Table Files” option from the “Data from Files” tab and browse for the file containing the above data. After clicking Next, we choose the Enable Transformation Step button to carry out the required data transformation.

Selecting the Data Transformation

Choose the Column tab and then choose the New button. It asks to specify the New column and the Row Condition. We specify column 3 as the source column and pick the values, which start with two as the Row Condition.

Transformed Data

On completing the above steps, we get the transformed data as shown below.

Load Script for Transformed Data

The load script for the Transformed data can be seen using the script editor. The script shows the expression, which creates the new column with required values.

Display Transformed Data

The transformed data can be seen by creating a Table Box using the option in the menu Layout → New Sheet Object.
