Validation rules contain a formula or expression that evaluates the data in one or more fields. When a user attempts to save a record, the rule checks whether the entered data meets the specified conditions. If the data fails to meet these criteria, Salesforce prevents the save operation and displays an error message to the user.
Key components of validation rules include:
1. Rule Name: A unique identifier for the validation rule
2. Active Checkbox: Determines whether the rule is currently enforced
3. Error Condition Formula: The logic that returns TRUE when data is invalid
4. Error Message: The text displayed when validation fails
5. Error Location: Specifies whether the error appears at the field level or page top
Common use cases for validation rules include:
- Ensuring required fields contain data based on certain conditions
- Enforcing proper formatting for phone numbers, emails, or postal codes
- Preventing users from entering dates in the past or future
- Requiring approval before specific field changes
- Maintaining consistency across related fields
Best practices for implementing validation rules:
- Keep formulas simple and focused on single business requirements
- Write clear, helpful error messages that guide users toward correct input
- Test rules thoroughly before activation
- Document the business purpose for each rule
- Consider the impact on data imports and integrations
Validation rules apply to all methods of data entry, including manual input, API calls, and data loader imports. Administrators should carefully plan validation rule implementation to balance data quality requirements with user experience and system integrations.
Validation Rules in Salesforce
What are Validation Rules?
Validation rules in Salesforce are formulas that verify the data a user enters in a record meets the standards you specify before the user can save the record. When a user attempts to save a record that violates a validation rule, Salesforce displays an error message and prevents the record from being saved.
Why are Validation Rules Important?
Validation rules are essential for maintaining data quality and integrity within your Salesforce org. They help ensure that:
• Data consistency is maintained across all records • Users enter complete and accurate information • Business processes are followed correctly • Errors are caught at the point of entry rather than downstream • Compliance requirements are met through enforced data standards
How Validation Rules Work
Validation rules use formula expressions that evaluate to either TRUE or FALSE. The key concept to remember is:
• When the formula evaluates to TRUE, the validation rule fires and the error message displays • When the formula evaluates to FALSE, the record saves successfully
Think of it this way: the formula defines what constitutes bad data. If the condition for bad data is met (TRUE), the save is blocked.
Components of a Validation Rule
Each validation rule contains:
• Rule Name: A unique identifier for the rule • Active Checkbox: Determines if the rule is currently enforced • Error Condition Formula: The logic that determines when the rule fires • Error Message: The text displayed to users when validation fails • Error Location: Where the message appears (top of page or specific field)
Common Validation Rule Functions
• ISBLANK() - Checks if a field is empty • ISNULL() - Checks if a field has no value (used for certain field types) • LEN() - Returns the number of characters in a text field • REGEX() - Validates text patterns like phone numbers or postal codes • ISPICKVAL() - Checks the value of a picklist field • PRIORVALUE() - Returns the previous value of a field before it was changed • ISCHANGED() - Determines if a field value has been modified
Example Validation Rules
Require a phone number when status is Active: ISPICKVAL(Status, 'Active') && ISBLANK(Phone)
Ensure close date is not in the past: CloseDate < TODAY()
• Required Fields: Only ensure a field has a value; validation rules can enforce complex conditions • Workflow Rules: Execute after save; validation rules execute before save • Triggers: Can perform similar validation but require code; validation rules are declarative
Exam Tips: Answering Questions on Validation Rules
1. Remember the TRUE/FALSE logic: The formula returning TRUE means the error fires. This is counterintuitive for many, so pay close attention to how questions are worded.
2. Order of execution matters: Validation rules run after assignment rules, auto-response rules, and before workflow rules, processes, and triggers. Know where they fit in the save process.
3. Watch for scenarios involving: Required fields, cross-object formulas, record types, and user-based exceptions. These are common exam topics.
4. ISBLANK vs ISNULL: Use ISBLANK for text fields and most other field types. ISNULL is primarily for numeric fields in legacy formulas.
5. Error location considerations: Field-level errors provide better user experience but can only be placed on fields included in the formula.
6. Bypass scenarios: Remember that validation rules can be bypassed using hierarchical custom settings or custom permissions when business processes require flexibility.
7. Read carefully: Exam questions often test whether you understand that validation rules prevent saves when conditions are met, not when they are not met.
8. Cross-object limitations: You can reference parent object fields but cannot reference child object fields in validation rule formulas.
