SAP GUI Support for tcode MDG_DISPLAY_MODEL

When a tcode is created you can select which SAP GUI it has support for from HTML, Java and the main Windows GUI you are probably most familiar with.

SAPGUI for HTML
MDG_DISPLAY_MODEL includes support for the HTML web based GUI. The SAP GUI for HTML generates HTML pages for each screen of the SAP transaction so that it can be executed within a standard web browser. Please note there are technical restrictions and possible incompatibility issues with certain browsers which means some transaction functionality may not function correctly.

SAPGUI for Java
