Cluster Table : Cluster tables are logical tables that must be assigned to a table cluster when they are defined. Cluster tables can be used to strore control data. They can also be used to store temporary data or texts, such as documentation.

A cluster table have many to 1 relationship. Cluster table are much more complex and you cannot display the data of a cluster table directly. Cluster table have be read and display via your ABAP program.

Table cluster is a special table type in ABAP dictionary. The data from different tables can be stored in a table cluster.

A table cluster should be used exclusively for storing internal control information (screen sequences, program parameters, temporary data, continuous text such as documentation).

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
