Hi,

BADI's are nothing but User Exits for Enjoy transactions.

SE18 Business Add-Ins: Definitions

SE19 Business Add-Ins: Implementations

You should have knowledge of Object oriented ABAP knowledge using Classes and Interfaces, methods and Events etc,

Hi,

BADI :- BADI - Business Add-Ins

Business Add-Ins are a new SAP enhancement technique based on ABAP Objects.

Each Business Add-In has :

– at least one Business Add-In definition

– a Business Add-In interface

– a Business Add-In class that implements the interface

SE18 : -- BADI Defination maintance .

SE19 :-- BADI implimentation maintance.

reward if useful.

Hi Radhakrishna,

BADI(Business Add-In) is the object oriented method of user exits...

Each BAdI has a definition and more than one implementation. The definition means the methods(in class concept) that are used for performing various functions. The BAdI definition can be viewed in SE18 transaction(for standard ones) and user-defined BAdIs can be created in the same transaction as well.

When you create a BAdI definition, an class interface will be automatically created and you can define your methods in the interface. The implementation of the methods can be done in SE19 transaction

You can use the transaction SE18 to define a new BAdI definition which may be implemented by other developers later.

A. BAdI Definition

1. SE18

2. Enter the name for the BAdI to be created in customer namespace and press "Create".

3. Enter a definition for your BAdI and on the interface tab enter a name for the BAdI interface. SAP proposes a name and it is pretty good. Meanwhile a BAdI class is also created which is not in our concern.

e.g for "ZTEST", SAP proposes "ZIF_EX_TEST" for the interface and "ZCL_EX_TEST" for the class.

4. Save your BAdI.

5. Double-click on the interface name. It will pass to a Class Builder session to make you implement your interface. If you are not familiar to the Class Builder; it's a bit like Function Builder and it will be easy to discover its procedure.

6. Save and activate your interface.

B. Calling your BAdI from an application program

1. Declare a reference variable with reference to the Business Add-In interface.

e.g. DATA exit_ref TYPE REF TO zif_ex_test.

2. Call the static method GET_INSTANCE of the service class CL_EXITHANDLER. This returns an instance of the required object.

e.g.

CALL METHOD CL_EXITHANDLER=>GET_INSTANCE

CHANGING instance = exit_ref .

3. After those two steps, you can now call all of the methods of the BAdI where it is required in your program. Make sure you specify the method interfaces correctly.

C. BAdI Implementations

1. SE19

2. Enter the name for the BAdI implementation to be created in customer namespace and press "Create".

3. It will request the BAdI definition name to which this implementation will be tied.

4. Enter a definition for your implementation and on the interface tab enter a name for the implementing class. Again SAP proposes a name and it is pretty good.

e.g for "ZIMPTEST", SAP proposes "ZCL_IM_IMPTEST".

5. Save your implementation.

6. To implement a method, just double-click on the method name and you will be taken to the Class Builder to write the code for it. Here you redefine the BAdI interface methods.

7. You must activate your implementation to make it executable. You can only activate or deactivate an implementation in its original system without modification. The activation or deactivation must be transported into subsequent systems

Hi,

BADI's are similar to User exits but make use of Object Oriented Concepts.

SE18 transaction has the definition of the BADI and SE19 is the transaction where the BADI can be implemented.
