You can paste objects that you have previously copied within the same message file, such as a message for a local element object, or types for a complex type object.
You can only copy and paste an object within the same message definition. You cannot copy an object and paste it into another message definition, either within the same message set or in a different message set.
To paste an object in the message definition from which you copied it:
Switch to the Enterprise Service Tools perspective.
Ensure that the Outline view is visible in the Enterprise Service Tools perspective. If the Outline view is not visible, from the workbench menu click .
In the Outline view, right-click the message model object that you want to copy to, then click Paste on the pop-up menu. Alternatively, right-click the object in the message definition editor Overview tab then click Paste on the pop-up menu.
