Formulas allow the calculation of numeric values in cells. In most cases, you can add a formula to any editable, numeric cell.
Formulas cannot be used in cells containing dates, text, and list boxes. Formulas cannot be created in read-only cells or in cells that show calculated totals.
Enter a Formula
You can enter a formula by typing directly in the cell, or using the formula bar.
When creating formulas, click Apply to apply changes. To delete a formula, select the cell with the formula and click Cancel . After you enter a formula, an f(x)? symbol appears. This means that the formula hasn't been calculated, yet. Save the sheet and the formula will display its evaluated result.
|A blue f(x)? indicates the formula hasn't been calculated, yet. Save the sheet to display the calculated results.|
A small triangle in the lower right corner of the cell indicates that the cell value was generated by a formula. Use the Cell Explorer to view formula details.
|Cells with formulas that contain errors appear in red.|
Using the Capture Method to Reference Other Cells
A formula typed into a cell can reference other cells on the sheet. Start by typing a equal sign (
=) into a cell. The cell formula contains an equal sign and nothing else. Now, click another cell in the sheet to include it in the formula. The cell now contains the code of the referenced account, as well as any other pertinent information about the selected cell.
The formula can be further modified by typing in simple operators symbols such as plus (
+), minus (
-), or multiply (
*). When the formula is complete, click Apply .
The Capture method only works when you are entering the information directly in a cell. It does not work if you edit or update the formula in the formula bar.
If a formula contains improper syntax (for example, a circular reference) the cell appears in red when the formula is saved. Hovering over the cell displays a tooltip to explain the cause of the error. For information on formula errors, refer to Troubleshooting Formulas.
Use Formula Assistant
Anywhere a formula can be written, the Formula Assistant is available. The Formula Assistant helps users construct syntactically-correct formulas. You can use it to insert valid accounts, assumptions, qualifiers, and functions into a formula.
To open the formula assistant:
- Select a cell to contain a formula, then click the Formula Assistant button .
- Click the Formula Assistant link in Account Details, etc.
Explore a Formula in a Cell
A small triangle in the lower right corner of the cell indicates that the cell value was generated by a formula.
To view the formula associated with a cell:
- Select the cell that contains the formula.
- Right-click the cell and select Explore Cell.
Recommended Development Process
Adaptive Insights recommends the following process for developing formulas:
- Plan what areas of your model will be impacted by the formula you’re creating.
You can create simple formulas that are used locally on a sheet or in a report. Or, you can create shared formulas that are used globally across your model. Formulas can be used in:
- Accounts – metric, modeled, cube
- Standard sheet data entry
- Cube data entry
- Formulas page (for level-based/shared formulas)
- Report calculations
- Allocation Rules
- Get familiar with formula functions and syntax.
Adaptive Insights provides a broad range of formula functions (mathematical, logical, date, and string) and account references you can use as building blocks. Refer to Reference: Formula Syntax for Account References and Modifiers and Reference: Formula Functions.
Don't forget that a formula will often include both a calculation and some conditions that must be met to apply the calculation. For example, a pay raise may be defined as a simple 10% pay increase, but you may also need to include other conditions in the formula. For example: Is the person a full-time employee?; Have they reached their anniversary date?; and so on.
- Get familiar with formula examples.
We've provided some common examples of formulas you can use for reference to see how formulas are typically constructed. In some cases, you can use these formulas as a starting point for your own models. Refer to Analyzing a Pay Rate Formula - A Detailed Walkthrough and Formula Examples.
- Pick your formula tools. You can:
- Create simple formulas by typing directly into a cell or formula bar on a sheet. Or, by typing into a Formula text field.
- Use the Formula Assistant. The Formula Assistant can help you construct formulas by guiding you in the use of formula syntax including terms, modifiers, and functions.
- Define shared formulas by navigating to Formulas.
- Import or paste a formula from an outside source (Excel, Word)
Adaptive Insights generally recommends using the Formula Assistant to prevent syntax and naming errors. Refer to Using the Formula Assistant.
- Start debugging your formula and correct errors.
As a formula developer, you may be inclined to write the complete formula and then begin debugging and checking for errors. This approach can save time for smaller, simpler formulas. However, more complicated formulas can include many variables, functions, and dependencies that need more attention. Therefore, it’s a good idea to test and debug each function separately to make sure it’s working as expected before combining the functions into a single formula. This saves time in the long run and helps you to quickly pinpoint the cause of issues if they occur.
Consider using a sandbox instance (if you have one) or a test account to try out your new formulas before rolling out the formula to a wider audience. Alternatively, have a rollback strategy (or backup) so you can easily restore an earlier version if things aren’t working as expected.
Also, add comments liberally through your formulas. Adding comments and spacing (tabs, spaces, and new lines) can make formulas much more readable and maintainable in the future, both for other users who encounter your formulas as well as for yourself in the future.
- Validate your formulas and troubleshoot any issues.
You can run Formula Validation to automatically check the current working version and list any formula errors, then use Cell Explorer to drill-down to the cause of the error. For more information, refer to Validating Formulas.
