Transactions that have been included on a final statement but have not yet been updated are protected. Changes to these transactions require the statement to be reverted to a pre-bill or "unbilled" first.

Note: Running final statements from the Generate Statements window overwrites the existing pre-bill, if one exists; therefore, to ensure that final statements are identical to reviewed pre-bills, it is important to instead create these final statements by clicking the Final Statements button in the Pre-Bill Tracking window.
