SageMaker Beispiele mit SDK für SAP ABAP

Die folgenden Codebeispiele zeigen Ihnen, wie Sie Aktionen ausführen und gängige Szenarien implementieren, indem Sie das AWS SDK für SAP ABAP mit verwenden. SageMaker

Aktionen sind Codeauszüge aus größeren Programmen und müssen im Kontext ausgeführt werden. Während Aktionen Ihnen zeigen, wie Sie einzelne Servicefunktionen aufrufen, können Sie Aktionen im Kontext der zugehörigen Szenarien und serviceübergreifenden Beispiele sehen.

Szenarien sind Codebeispiele, die Ihnen zeigen, wie Sie eine bestimmte Aufgabe ausführen können, indem Sie mehrere Funktionen innerhalb desselben Services aufrufen.

Jedes Beispiel enthält einen Link zu GitHub, wo Sie Anweisungen zum Einrichten und Ausführen des Codes im Kontext finden.
