Today we are getting technical: We are talking about the UI techniques and layers in TM. We start from the different end user presentations techniques like the Netweaver Business client or the portal. Getting closer to the backend we visit WebDynpro and the Floorplan Manager. And finally we come to our magic Floorplanmanager-FPM-Integration-layer FBI. Some words about enhancements are also not missing. We try to give tips and tricks on our journey through the different layers.
