Copying and pasting between objects
If you have fields that contain the same information in multiple objects, you can save time by copying the information.
Procedure
You can copy fields, for example, between entity and link types, like this:
In the Database Explorer window, select the entity type or link type. This displays its fields in the Details window.
In the Details window, select the field that you want to copy, right-click and from the shortcut menu, select Copy.
In the Database Explorer window, select the object to which you want to add the field. For example, to paste a field into a link type, ensure the link type fields are displayed in the Details window.
In the Details window, right-click and from the shortcut menu, select Paste.
