Hi @Sangeetha AR,
The best way to do this would be to create a Formula Column using the Insert tool in the Data tab. From here you will be prompted to enter the name of your Formula Column and its formula- if you start typing the name of the object your driver is originating from the Formula should autocomplete with the format " ={Object (Cost driver) }".
Remember to set the Format of your Formula Column to Currency and tick the "Summable" box at the bottom if applicable and you should be able to report on your drivers in separate columns from the same table. For more information on Formula Columns please see this article.
Best regards,
