Suchhilfe in Fiori Elements über nativen oData-Service mit manueller Definition der Annotationen in der MPC_EXT

Mal eine ganz wüste Möglichkeit Annotationen in einem oData-Service umzusetzen. Aber mit einem 7.40 Release ohne Fiori-Programmiermodell oder RAP bleibt einem eben nicht ganz so viel übrig. 🙂

Hier geht es darum eine Suchhilfe in einem oData-Service bzw. der darüber liegenden Fiori Elements-Anwendung zu implementieren. (Der nächste Schritt ist dann die Erstellung eines Dropdowns)

Hier die Implementierung der entsprechenden MPC_EXT-Klasse.

ENDMETHOD.

Und schon erscheint die richtige Suchhilfe wenn auch mit etwas Aufwand.
