Manual versus Automatic Execution 

A validation can be invoked in two different ways as follows:

·        Manual: You can manually run any validation or validation group against the selected records in the Records pane at any time.

·        Automatic: You can define any validation so that MDM runs it automatically every time you edit and attempt to save a record.

 

Automatic execution then has two different kinds of behavior:

·        Warning: MDM simply warns you before saving a record if any of the automatic validations fail when you press Shift + Enter.

·        Error: MDM not only warns you but also prevents you from saving the record if any of the automatic validations fail.

Validation errors are downgraded to warnings on checked out records. The error occurs upon check in. For more information, see Checking Out Records.
