The efficiency and versatility for the implementation of formulas in an on-demand database is improved. Workflow field formulas are triggered by actions in a workflow, to produce values in fields. Resulting values are protected by preventing a subsequent reevaluation of the workflow field formula from taking place when values of input fields used in the workflow field formula change.
