TLDR; Salesforce Validation Rules act like digital bouncers, ensuring data meets specific criteria before saving. They prevent errors and enforce business rules. However, limitations exist, like the inability to perform cross-record checks. Administrators must be aware of these constraints and may need other tools for complex validations.
Salesforce data validation rules
So we've discussed controlling duplicates in Salesforce to achieve better data quality. Another way of maintaining data quality in Salesforce with built-in functionality, as apposed to a paid premium solution, is with the application of validation rules. Validation Rules in Salesforce are put in place to ensure that data entered by users meets specific criteria before a record can be saved. For instance, a requirement to have a name field populated. Admins set up these rules as statements resembling yes/no questions. If the criteria aren't met, an error message prompts users to correct the record before saving. While it’s simple, it can still be beneficial for an organization's basic needs.
Validation Rules Purpose:
Validation rules verify that the data entered by users in Salesforce meets the standards you specify before they can save it. Imagine a validation rule as the bouncer guarding the entrance to a nightclub: you have to have adhere to the dress code in order to get in. You might also need to show some ID. Without following the rules of the club, you don’t get in! For your Salesforce data, Validation Rules help you to maintain data integrity and accuracy.
*Note – verification is slightly different to validation. While validation could be seen as a bouncer that makes sure you have the right clothes and checks your ID to make sure you are old enough – verification would be a police check inside the club to make sure the ID you used to access the club is a real ID and not fake.
How it works:
- Rule Criteria: A logical rule that defines whether the data is valid. It's often written in a formula-like expression. For example, if [name] = [empty] do not allow creation.
- Error Message: A customizable message that appears when the rule criteria are violated, guiding the user to correct the data.
Common Applications:
- Ensuring required fields are filled out.
- Validating formats, such as phone numbers or email addresses.
- Enforcing business rules, like closing dates being in the future.
Use Case Scenarios:
- Identify common data entry errors and create rules to prevent them.
- Analyze business processes to implement rules that enforce business logic.
Tips for Efficient Rule Creation:
Time for tips! Testing validation rules in Salesforce is crucial to ensure they function as intended and do not hinder legitimate data entry. Here are some tips for effectively testing your validation rules in Salesforce:
- Understand the Requirements: Clearly understand the business requirements that lead to the creation of the validation rule. Be aware of the expected behavior when a validation rule is triggered.
- Create Test Scenarios: Identify various scenarios that should trigger the validation rule. Include cases where the validation should be successful (False) and cases where it should fail (True).
- Use Sample Data: Work with sample data that replicates real-world scenarios. Utilize data that covers different combinations of conditions specified in the validation rule.
- Test Positive and Negative Cases: Test scenarios where the validation rule should allow data entry (negative cases). Test scenarios where the validation rule should block data entry (positive cases).
- Use Multiple User Profiles: Validate the behavior of the validation rule for different user profiles. Ensure that users with different permissions are appropriately restricted or allowed by the validation rule.
- Leverage Different Record Types: If your Salesforce org uses multiple record types, test the validation rule against each relevant record type.
- Verify Error Messages: Confirm that the error messages associated with the validation rules are clear, informative, and guide users on how to resolve the issue.
- Bulk Data Testing: Assess how the validation rule behaves when dealing with bulk data uploads or updates. Validate that the rule does not impede the performance of data-related operations.
- Regression Testing: Whenever changes are made to the validation rules or the Salesforce configuration, perform regression testing to ensure existing functionality remains intact.
- Use Salesforce Developer Console: In Salesforce Developer Console, you can simulate the behavior of validation rules by creating test records and evaluating how the rules impact those records.
- Document Test Cases: Document your test cases and their outcomes for future reference and to facilitate collaboration with other team members.
- Review Audit Trails: After testing, review Salesforce audit trails to understand which validation rules were triggered and the associated details.
- Find the Right Combination of Strictness and Flexibility: Too many or too strict rules can hinder user productivity. Find a balance that maintains data quality without overly complicating data entry.
While this is a simplified overview of Salesforce Validation Rules, you hopefully get the picture how they work. By effectively utilizing Salesforce data validation rules, you can significantly enhance the quality and reliability of your Salesforce data. Remember that the goal is to support and streamline business processes, not to create barriers for your users. With that being said, there are limits to the powers of Salesforce validation rules that you should take into account.

Limits of Validation Rules and Data Validation with Salesforce
Data validation processes can range from simple checks (e.g., verifying that an email address follows the correct format) to more complex validations involving multiple conditions or dependencies among different data fields, like geocodes. While Salesforce does offer some basic validation methods, there are some limitations.
- Cross-Record Verification: Validation rules focus on individual records; they can't execute cross-record checks or validate data across multiple objects. For such needs, Apex triggers are more suitable.
- Exceptions during Specific Processes: In some scenarios, like lead conversion, validation rules might not apply uniformly. For instance, during lead conversion, tasks may skip validation even though the lead itself is converted.
- Limitation in Certain Scenarios: Salesforce has areas where validation rules won't function as expected. For instance, campaign hierarchies or during mass transfers of record ownership, the rules might not trigger.
- Scope during Mass Record Changes: When using tools like Mass Transfer to change ownership for multiple records, validation rules might not execute. They typically function when records are altered individually.
This section of our guide has highlighted the purpose, functionality, and common applications of validation rules, emphasizing their significance in enforcing business logic and preventing common data entry errors.
To efficiently implement validation rules, it is essential to follow best practices in their creation and testing. The provided tips, ranging from understanding business requirements to utilizing sample data and conducting regression testing, serve as a guide for administrators to ensure the effectiveness of their validation rules without impeding legitimate data entry.
While useful, it is crucial to recognize the limitations of validation rules within the Salesforce ecosystem. These limitations include the inability to execute cross-record checks, exceptions during specific processes like lead conversion, and constraints during mass record changes. Administrators should be mindful of these constraints and, when necessary, leverage other tools such as Apex triggers for more complex validations or cross-record verifications.
