Hope this example gives a idea.

If you declare a types statement inside your program, you can refer that type only in your program. BUt if you declare a type in a type group, then it is visible to all the programs(Provided they have declare the type-pools: <Type pool name>.) .

It is a global area where you can define your types which can be accessed anywhere.

Regards,

Ravi

Hi,

If u add this stmt in ur ABAP program,

TYPE-POOLS tpool.

It includes the types and constants of a type group [Which will be created through SE11 transaction].

Class-pool:

This is a container for global classes .

TYPE Pools can be thought of as an include having TYPE declarations.

The use of this in your program gives your program access to these TYPE declarations which can then be used directly in your program when declaring new data declaration.

Class pool is actually a kind of program which is created when you create a class in transaction SE24. You cannot create a class pool from se38 and even if I told you a class pool program name , if you try to open it will only open SE24.

This contains all the information about the class.

Hope this helps

Vijay ,

Pls. go through this.

10. What is a table pool?

A table pool (or pool) is used to combine several logical tables in the ABAP/4 Dictionary. The definition of a pool consists of at least two key fields and a long argument field (VARDATA).

11. What are pooled tables?

These are logical tables, which must be assigned to a table pool when they are defined. Pooled tables can be used to store control data (such as screen sequences or program parameters).

Pls. mark if useful

12. What is a table cluster?

A table cluster combines several logical tables in the ABAP/4 Dictionary. Several logical rows from different cluster tables are brought together in a single physical record. The records from the cluster tables assigned to a cluster are thus stored in a single common table in the database.
