Formula TracePrecedents – Cells used in a formula Dependents – Where this cell is used elsewhere in the spreadsheet
Case Study Problem: An overworked analyst at a Debt Lending Bank is asked to understand the Debt formulas in a model sponsored by a building company prior to agreeing to a credit limit. The formula is:
Solution: Navigator Utilities Trace module allows the user to understand complex formulas in a fraction of the time of traditional methods Step 1: Use the quick keys Ctrl + T to launch Navigator Trace
The complex formula is broken down into its precedent cells with other useful information:
Step 2: You navigate through all of the Precedents using the keyboard arrows or mouse pointer. As you select a Precedent you will be taken to this cell in the spreadsheet even if it is on another sheet or even in a separate spreadsheet. When you select a Precedent notice that the precedent is highlighted as it appears in the original formula allowing the user to not only see where the cell comes from but see how it is used in the formula.
When a Precedent is selected the user is also shown the
formula that is in the Precedent cell. The user can then change this formula in
the window And use the
The user can then set this Precedent cell as the new Origin and the Navigator Trace will then show the user the Precedents of this new cell. This can be done many times Precedents and Dependents alike. This creates a history and you
can use history navigation keys
*** You can always get back to
the first cell by pressing
*** You can always clear the
history by pressing
Step 3: You can use All
of the above functionality for both Precedents and Dependents with the press of
one button Step 4: Blue Display arrows for Precedents and Dependents or both can be displayed in combination with the above functionality
By checking the appropriate box *** Note: That Navigator Trace window can be placed according to your preference {Please see the Navigator Audit Case Study} *** Note: That ALL Navigator Windows are modal. You can keep them opened and still edit your Excel Spreadsheet *** Note: All User preferences like having Precedents blue display arrows being shown are remembered ( as per your last choice) by Navigator Utilities and these customised setting are respected and shown next time you launch Navigator Utilities. Step 5 – Using Navigator Trace the overworked Analyst was able to see where the Precedents come from and how they are used in the formula and used this information to quickly ascertain what the formula was doing. It took him about 1 minutes to understand this complex formula:
The formula is simply doing the following: =Opening Balance x (1+ Interest Rate)^(Day count) Also noted using Navigator Trace was: The formula uses a logic flag to handle both Nominal Debt and Indexing Debt. And YES it is correct.
