Data Validation

AB.

Sure, I'd be happy to provide a detailed explanation for each statement and whether it is true or false for data validation in Salesforce:

A. Data Validation can enforce data integrity as well as make a field required in the page layout - True Data validation can be used to ensure that data entered into a field meets certain criteria. This could be ensuring that a date field is entered in the correct format, or that a text field contains a certain number of characters. Additionally, validation rules can be used to require that a field is filled in before a record can be saved.

B. Data Validation can prevent duplication of records - True Validation rules can also be used to prevent the creation of duplicate records by checking for certain criteria in existing records. For example, a validation rule could be created to prevent the creation of two accounts with the same name.

C. Data Validation run on the client machine after the user clicks the Save button - False Validation rules actually run on the server, before a record is saved. If the validation rule fails, the user is presented with an error message and the record is not saved.

D. Data Validation rules are not enforced when using API & import operations - False Validation rules are enforced when using API and import operations, just as they are when a user manually saves a record. However, it is important to note that validation rules are not run when records are deleted using the API.

E. Validation rules can be activated / deactivated by the user - False Validation rules cannot be activated or deactivated by a user. They can only be created, edited, and deleted by users with the appropriate permissions. Once a validation rule is active, it will run whenever a user saves a record that meets the rule criteria.

I hope this explanation helps!
