Cutting and Pasting Categories 

You can also use the Cut, Copy and Paste commands to move, copy and merge categories in the taxonomy tree. The conditions listed in the table below must be met in order to use the cut and paste operations.

When you use the Cut and Copy commands, MDM places a blinking highlight around the nodes that have been cut or copied.

Sibling nodes in a tree cannot have the same name. When you cut-and-paste a node to move it in the tree, MDM automatically renames it to Node Name (n) and when you copy-and-paste a node to copy it in the tree, MDM automatically renames it to Copy (n) of Node Name if its name would be the same as that of an existing sibling node in the new location (where ‘n’ is the first available numeric value that will avoid a conflict).

Operation	Constraints
Cut Category	●      Must be in Hierarchy or Taxonomy mode ●      Tree must have focus ●      Exactly one node must be selected ●      Root node cannot be cut
Copy Category	●      Must be in Hierarchy or Taxonomy mode ●      Tree must have focus ●      Exactly one node must be selected ●      Root node cannot be copied
Paste as Sibling	●      Must be in Hierarchy or Taxonomy mode ●      Tree must have focus ●      A node must already have been cut or copied ●      Exactly one node must be selected ●      Root node cannot have siblings ●      Sibling nodes cannot have the same name
Paste as Child	●      Must be in Hierarchy or Taxonomy mode ●      Tree must have focus ●      A node must already have been cut or copied ●      Exactly one node must be selected ●      Destination node cannot be an alias ●      Destination node cannot have an alias ●      Destination node cannot have a matching set ●      Destination node value cannot currently be assigned to a lookup field ●      Sibling nodes cannot have the same name
Paste as Merge	●      Must be in Hierarchy or Taxonomy mode ●      Tree must have focus ●      A node must already have been cut or copied ●      Exactly one node must be selected ●      Destination node cannot be the root ●      Destination and source node cannot be the same ●      Destination and source node cannot have children ●      Destination and source node cannot be an alias ●      Destination and source node cannot have a matching set

For proper organization of the records within an MDM repository, a taxonomy lookup field can normally be assigned only to the value of a leaf-node category in the taxonomy table, which can sometimes prevent a tree operation that would otherwise turn a leaf node into a parent node. However, MDM does not detect if records have already been assigned to a category until after you attempt to perform the operation. As a result, the Paste as Child menu item is available even if the destination category has records assigned to it, even though this would make the node into a non-leaf node. If you choose Paste as Child in this situation, MDM does not permit the paste and instead displays an error dialog.
