A DDE link is created whenever the DDE spreadsheet function is used in a cell formula.

DDELink

The com.sun.star.sheet.DDELink service is only used to query the link's parameters using the com.sun.star.sheet.XDDELink interface, and refresh it using the com.sun.star.util.XRefreshable interface. The DDE link's parameters, Application, Topic and Item are determined by the formula that contains the DDE function, therefore it is not possible to change these parameters in the link object.

The link's name used for the com.sun.star.container.XNameAccess interface consists of the three parameter strings concatenated.
