BOR-Integration

In diesem Beispiel laden wir eine im BOR (Business Object Repository) gespeicherte Excel-Datei, verändern diese und Speichern sie als neues Dokument wieder im BOR ab. Dabei wird die Excel-Datei nicht auf dem PC zwischengespeichert. Stattdessen werden die entsprechenden Methoden der Desktop Office Integration verwendet.

Information

Die in diesem Fall als Template verwendete Excel-Datei muss mithilfe der Transaktion OAER in das Business Objects Repository geladen werden!

TIPP 1:
Sie können auch eigene „Klassen“ definieren. Um ZMYCLASS zu erstellen, rufen Sie die Transaktion SBDSV1 auf und pflegen Sie den Eintrag ZMYCLASS und ordnen Sie den Objekttyp „OT“ zu. Mit Transaktion SBDSV3 können Sie einen Text definieren.
Sie können auch einen Exit-Funktionsbaustein eintragen, wie z.B. DYNDOC_BDS_APPLICATION_EXIT, der bei PICTURES-OT hinterlegt ist. Wenn Sie Ihren eigenen Exit verwenden, können Sie z.B. das Hochladen bestimmter Dateitypen in bestimmten Klassen verhindern, automatisch Schlagworte hinzufügen oder zusätzlich wichtige Attribute abfragen.

TIPP 2:
In diesem Programmbeispiel wird die Exceldatei wieder unter dem Typ „BDS_SHEET – Tabellenvorlage“ gespeichert. Sie können auch einen anderen Typen festlegen! Schauen Sie dazu in die Transaktion OAC2.
