Embedding an object is a form of copying in which the copied object resides in the destination file only — with no link to the source file. You edit the object using the same tools that are available in the source program (though you don’t need to use the same source program). When you embed an object, any changes you make to that object exist only within that destination file. For instance, you can activate and edit the object only from within the Microsoft Project file in which it’s embedded.
Therefore, changes you make to an embedded object do not change the source file from which you copied the object. Likewise, later changes made to the source file are not reflected in the embedded object, because there is no link between the two files.
You can link or embed objects with any program that supports object linking and embedding. With either method, objects can be placed in any graphics area: the chart portion of the Gantt Chart view; the Objects box of the Task Form view or Resource Form view; headers, footers, and legends of printed views and reports; and Note boxes. Text objects can be linked to sheet views.
