Improve the quality of your data using validation rules. Validation rules verify that the data a user enters in a record meets the standards you specify before the user can save the record. A validation rule can contain a formula or expression that evaluates the data in one or more fields and returns a value of “True” or “False”. Validation rules also include an error message to display to the user when the rule returns a value of “True” due to an invalid value.
|Rule Name||Unique identifier of up to 40 characters with no spaces or special characters such as extended characters.|
|Active||Checkbox that indicates if the rule is enabled.|
|Description||A 255-character or less description that distinguishes the validation rule from others. For internal purposes only.|
|Error Condition Formula||The expression used to validate the field. See Build a Formula Field and Formula Operators and Functions.|
|Error Message||The message that displays to the user when a field fails the validation rule.|
