You can create a map by right-clicking any resource in the Repository navigator and choosing the New > Map menu item. Alternatively, in the standalone version you can click the New Map button. You then specify the map type, enter a name for the map, and select the input and output structures for the map using the [New Map] wizard. Alternatively you can end the wizard after naming the map and drag the input and output structures to their respective panels in the map editor. Make sure the Link with Contents button is not selected. Otherwise, when you click a structure you want to drag to the map, the editor window will switch from the map view to the structure properties view, so you will not be able to drag the structure to the map.
