You can choose the deployment type by clicking on one of the three buttons across the top of the page: HTML, SharePoint, or Google Gadget. Make sure you choose the option that’s appropriate for your environment. For instance, in a SharePoint environment you would select a SharePoint Extension because SharePoint doesn’t support native HTML code or Google Gadgets.
Next you must choose the business system where the extension will operate. You can select an existing business system or add a new one (the “Create new” menu option). Click Continue to move to the next step in the wizard.
