MBT Logical Object Lister (LOL) is no joke. It’s a simple tool for displaying metadata of the complete SAP® Business Warehouse and SAP BW/4HANA® object model (TLOGOs)*. You can quickly browse which object types are available in a system, find out what database tables are used to store the metadata of objects, what icons are associated with an object type or sub-type, and many more properties of the object types. You can also jump with a double-click from the tool to the listed DDIC and ABAP objects.
