If you want to restore the Unknown value(s) after calculating, you can by using the Restore Unknowns button. The effect of Restore Unknowns is similar to Undo but differs in that even if you have further adjusted the cash flow data since solving for unknown values, the Unknowns will be restored.
To Restore Unknowns
- From the Home ribbon's Compute group, choose Restore Unknowns or press [Ctrl]+[K].
