How to link pledges to their payments and write offs in a Crystal Report
Export the pledge payment gift information from Gifts/Installments/Payments, and export the write off gift information from Gifts/Installments/Payments/Write Offs/Amount. In Raiser's Edge 7, every single pledge does have an installment schedule, even if the user does not set one up. If the user doesn't set one up, then it is a single installment. Therefore if you export the Gifts / Installments table information, this will capture payments and write offs for all pledges.
