Change captions for columns to better communicate what the column represents. Often we use calculated columns with a formula to display data in a new column. The default caption for these columns is not descriptive of the new data This is when you can use the Captions page to change how these columns print. You can the caption for any column. For example you might want to abbreviate Quantity to Qty. in order to take up less space.
Click on Captions from the Designer screen. In the page that opens, change any caption. In the following screen the caption for the last row has been changed to Turnover.
Now when you print this report, the caption will print the new value you entered.
