In order to use the definitions of a type group, you have to integrate the type group into the program.
The TYPE-POOLS statement integrates the type group tpool into the current context. You can specify it in the global data declarations of an ABAP program or in the declaration section of a class or interface. The data types and constants of the type group are visible as of this statement in the current context.
In ABAP, you can either use a Data Dictionary Data, Data Type or your own user defined datatypes. In case of the user defined Data Type you need to define your own type structure.
There are two ways you can achieve this. In a ABAP program you can use the Type Keyword. Then this becomes local to that ABAP Program. In the Data Dictionary you can define and can use it across any program in ABAP.
When you have several such types, you can use them all at once common place.And all of them are stored in a Type Pool.You can navigate from SE11 to type pools.
Examples: vrm.slis. All of these have all the common structures and pools to be used across all the programs.
