Pledge balance will only display a figure for pledges and MG pledges in The Raiser's Edge.

Other gift types do not have a balance,such as a cash, pay-cash (or any pay-transaction), or a recurring gift. If the Pledge Balance field is selected for output in a query, export, or a report, this field will display $0.00 or be blank for a non-Pledge or non-MG Pledge gift record.
