Learning Objectives
After completing this unit, you'll be able to:
Describe two use cases for validation rules.
List the elements of a validation rule.
Create a validation rule.
Introduction to Validation Rules
Validation rules verify that data entered by users in records meets the standards you specify before they can save it. 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.” When the validation rule returns a value of "True", this confirms that the data entered by the user contains an invalid value. Validation rules can also include error messages to display to users when they enter invalid values based on specified criteria. Using these rules effectively contributes to quality data. For example, you can ensure that all phone number fields contain a specified format or that discounts applied to certain products never exceed a defined percentage.

Defining Validation Rules
You can create validation rules for objects, fields, campaign members, or case milestones. In these steps, we create a validation rule that fires when a user tries to save an account with an account number of incorrect length.
