The list box along the left edge of the layout tab contains all of the available data columns you can print for the report.

 

Some reports have over 100 columns available for printing.        

 

The list is sorted alphabetically to help users find the column they are looking for quickly.

 

Fields may be moved from the available list by first clicking the desired field with the left mouse button and then while holding the mouse button down, dragging it to the desired data row, group list, or sort list.

 

Data fields are moved from the available list to the data rows and copied to the group and sort lists.
