Starting with version 11 4D no longer supports subtables. Subtables from databases created in versions 2004 and earlier will be converted to normal tables with a special relation created by 4D. Features that support this special relation are deprecated and will be removed from 4D in a future release. Databases that rely on these features should move away from this special relation and the commands it supports. This technical note will detail one of the possible paths to take to migrate from subtables to standard related tables.
