cluster table
Before Release 7.53, table category of a database table in ABAP Dictionary. A cluster table did not exist as a table instance on the database. Instead, multiple cluster tables were saved in a table cluster in the database. Only ABAP SQL could be used to access cluster tables. Certain other restrictions also applied. Cluster tables are no longer supported from Release 7.53. Any existing cluster tables were transformed to transparent tables.
