Unlink a dimension or measure in a visualization from its master item to edit only the current instance of the dimension or measure. Unlinking removes the connection to the master item, and the dimension or measure becomes independent. If you want to update all instances of a linked dimension or linked measure, you must edit the master item. For more information, see Editing a master dimension or Editing a master measure.
