This method can be applied to a variable based on a business component type of a Transaction object.
It performs the same validations that are carried out when the Save method is executed, but without updating the database (it performs a rollback to cancel any modification).
It is used when you want to validate data (and mainly to give feedback to the user) before actually updating the database.
