Custom Business Rule

The default behavior of Duplicate action is to execute the New action and automatically copy values from the current row into the fields of the record. If it is necessary to change the default behavior, a custom business rule must be used.

A user can duplicate a customer using the Duplicate context menu option in Customers grid.
