Hi,

Cluster Table : Cluster tables are stored in table cluster. Cluster tables can accessed by atleat 2 key fields. They can used to store long text such as documentation.

A many cluster table have many to one relationship between appliation server to database. Data stored in cluster table is in RAW format which can not understand directly by SQL statements.

So, we normally use the Function modules like 'READ_TEXT' , 'SAVE_TEXT' etc

EX:- STXL, STXH for scripts
