When pasting a item to a context where the object's name already exists, the new object is renamed and  the paste succeeds. An exception is thrown with error code tagTDAPI_ERRORCODES.TDOLE_REQ_EXISTS. This occurs, for example, when copying a Req and pasting it under the same parent requirement.

For the list of classes that support copy and paste, look in the index under "ISupportCopyPaste(n)", where n is the number of the most recent version.

If your application is in a scripting language that requires interfaces that inherit IDispatch, use ISupportCopyPaste3 or higher.
