There isn’t a report designed for that, but you might be able to customize the Fee Listing Report. A better idea would be to use the Time Manager. Set the filter for the specific date range, WIP, etc. Once transactions are displayed, right click in the grid and choose Select Grid Fields. If Original Amount, Bill Amount, and Write Up/Down Amount are not already in the grid, drag over Original Amount, Bill Amount and Write Up/Down Amount. You can then sort by Write Up/Down Amount and view those where there is a value other than zero. You can either open the individual transaction in the Fee Entry Window or view the description in the Detail Pane over to the right.
