  9. Integration DnD with Sap – Part I Next slide shows a first example of integrationbetweenHtml 5 and Sap. Given a draggableelement of type <table>, we can export his contents (DOM innerHTML) in excel format by calling a Sap SICF Service synchronously submitting an HTML form via POST method. SAP Service parses HTML code as XML using class CL_IXML and our custom class ZCL_HTML_TABLEPARSER. HTTP Response will return a binary Excel as Attachment.

  10. Integration DnD with Sap – Part II Next slide shows a second example of integration. Dragging an AIRLINE image in a target area: On Drop event we can do an AJAX request to Abap SICF Service. Response is a JSON Object containing SFlightsData.
