Mapping Sets can also be cloned if no splitting is required. There are two ways of cloning a Mapping Set:
by copying only the sources of the selected Mapping Set → using the Clone...
action
by populating the targets as well → using the Clone with targets...
action
Both actions can be reached from the Context Menu after right-clicking on the desired Mapping Set.
The action brings up the dedicated Clone Mapping Set Wizard where the target Mapping Set properties can be specified.
Clicking Finish
in the wizard will generate the new Mapping Set, which will be listed in the Mapping Set View.
