Introduction: This document explains the very basic topic of creating the type group and its use in ABAP program.

What is type group: There are several type groups available in SAP. For example ‘ABAP’ and ’SLIS’ etc. To use them in program we use key word ‘TYPE-POOLS’. It allows us to define non-predefined types. Combination of all such non-predefined types is knows as type-pool or type-group. In simple terms, if we want to use some custom types in various programs then we need not define them separately, we can simply create a type group in ABAP dictionary and use that in our programs.

Steps to create:

i)              Go to transaction SE11; select the radio button ‘Type Group’. Click ‘Create’ button.


         Note: – Maximum length of type-group name can be ‘5’.

ii)             Provide some meaningful description in short text


And click on save button.

iii)            Then next screen appears where we can write our source code as highlighted in the below screenshot. As an example, I have created two constants. One thing that needs to be taken care of while declaring the structures, constants, etc. in Type Group is that every object must start with ‘<name of type group>_’. In this example the constants that are declared starts with ‘ZATYP_’. The system gives syntax error in case the above naming convention is not followed.


iv)            Now save /wp-content/uploads/2012/10/4_147662.png and activate/wp-content/uploads/2012/10/5_147663.png    the type group.

v)             Now we can use the type group created above in our SAP programs. Please find below the screenshot for the same


Output will be following:


Summary: In this way we can create type group and use it in ABAP programs.

    Hello Ashish,

    thank you for sharing this. However, I would prefer using ABAP OO-Interfaces as type-pool replacement which can deliver also types and constants. When using such an interface, you will gain a lot more control over your types and constants, because 1) the compiler likes them more;-) and 2) you can change them much more independent as it will be in type-pools.

    When defining huge type-pools, you will have a lock problem, when changes of a type-pool are transported separately from your development.

    Kind regards,

      Hi Hendrik,

      Thanks for ur valuable comment. Actually i posted this document to describe type-pool for beginners, who want to just check what is type-pool and how to create that.

        Hello Ashish,

        you have well done. In the past, I have been faced more than once with this “huge-type-pool” problem. Out of the historical-view the ID-limitation to 5 characters is now a problem, because implementation-projects are often restricted through naming-conventions and so they have at least.

        I just would suggest, to look forward to a solution, which enables every modern implementation to use an equal OO-pattern.

        Kind regards,
