You can delete a formula component only if it is not being used in any rules or templates. To see if any rules or templates are using the formula component, you can show its usages. (See Showing the Usages of Formula and Script Components (Financial Management, Planning, and Essbase Block Storage Application Users Only).) If a formula component is used in a rule or template, and you no longer need to use it in that rule or template, you can remove it from the rule or template, and then delete the formula component. You can also delete the rule or template, which deletes the formula component within it.
To delete a formula component:
In the System View, expand the Financial Management, Planning, or Essbase application type, the application, the calculation type (for Financial Management), the plan type (for Planning), or the database (for Essbase), and Formulas.
Right-click the formula you want to delete and select Show Usages to make sure no rules or templates are using the formula component. If any are, you must remove the formula component from them. See Removing a Component from a Flow Chart (Financial Management, Planning, and Essbase Block Storage Application Users Only).
Right-click the formula you want to delete, and select Delete.
