This screen displays which database tables require the most disk space. By default, the 50 largest tables are shown but you can change this on-screen. Implementing an SAP Data Management concept (archiving, deletion, reduction and avoidance) helps to reduce table growth and manage the size of your database.
Using a dropdown box, a single schema can be chosen, or all schemas.
You find this function in the DBA Cockpit navigating to Space →Largest Tables.
