What are Validation rules in Salesforce?

Validation rules in Salesforce are used to improve the quality of data. These validation rules verify the data when the user enters a data record to maintain the standards. Validation rules in Salesforce also consist of formulas and expressions to evaluate the data record in one or more fields and also returns the output either in “true” or “ false” formats. Validation rules also add the error messages to which will be displayed in the output when the user returns the “true“ because of an invalid value. 

After these validation rules, users can perform the below tasks such as;

1. User can choose to create a data record and also can able to edit already existing data records.

2. After this user choose the “save” button to save all the modified data records.

3. Validation rules can be verified in two ways:

a. If all the data values are valid and also you have saved the record.

b. suppose you have uploaded the invalid data, you will get an error message and this data record will not be saved.

4. User can also perform necessary changes to the data record and click the save button.

Tips for writing validation rules:

Below are the basic tips for writing the validation rules:

1. If you have decided to perform validation, you have to go for all settings in the configuration tab; this can makes the record failed validation. This can include the following procedure such as assignment rule, field updates, filed-level security, and hidden fields on the page layout.

2. You should be careful and no need to create any contradiction validation rules for the same data fields. And users cannot save the record.

3. When referencing the data fields in any validation formula, and make sure that all the objects are deployed.

4. Now use the RecordType.Id merges data field in the formula to apply different validations for different types of records.

5. You don’t have to begin a validation rule formula with the IF function. Here Boolean expressions can work like this;

Correct: CloseDate < Today ()

Incorrect: If (CloseDate < TODAY (), TRUE, FALSE)

6. One more important thing is that, when a validation rule contains any fields like BEGINS or CONTAINS function, this processes the data fields as valid.

7. When you are using a validation rule this ensures that a number of fields contain many specific values if you using the ISBLANK function this doesn’t contain any data values.

The function is as follows;

OR (ISBLANK (field_c), field_c <> 1)

8. Avoid using the ISClosed or ISWon functions to merge the fields while performing the validation process.

Tips for writing validation rule for error messages:

1. Give instructions to Salesforce developer. Suppose if you get an error message like “invalid entry”, this doesn’t mean tell you that, what type of data entries are valid. So you have to use more specific terms like “close date must be after today”.

2.  Always good use the field labels. Sometimes users may not know that label fields are failing to perform validations. This only happens when the error messages appear at the top of the page.

3. If you have a multilingual organization, it’s good to translate the error messages. With the help of translate workbench, you can translate the error messages.

4. Assigning the numbers to validate rules and error messages. This helps you to identify the source of error.
