I have already answerd this question in below thread.

Difference between BADI and User Exits

http://www.sap-img.com/abap/difference-between-badi-and-user-exits.htm

Business add-ins are enhancements to the standard version of the system.

Business Add-In is a new SAP enhancement technique based on ABAP Objects.

They can be inserted into the SAP system based on specific user requirements.

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

In order to enhance a program, a Business Add-In must first be defined

Subsequently two classes are automatically generated:

• An interface with ‘IF_EX_’ inserted between the first and second characters of the BADI name.

• An adapter class with ‘CL_EX_’ inserted between the first and second characters of the BADI name.

The Application developer creates an interface for this Add-In.

There are multiple ways of searching for BADI.

• Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE

• Finding BADI Using SQL Trace (TCODE-ST05).

• Finding BADI Using Repository Information System (TCODE- SE84).

1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for ‘CL_EXITHANDLER=>GET_INSTANCE’.

Make sure the radio button “In main program” is checked. A list of all the programs with call to the BADI’s will be listed.

The export parameter ‘EXIT_NAME’ for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter ‘INSTANCE’ will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.

2. Start transaction ST05 (Performance Analysis).

Set flag field "Buffer trace"

Remark: We need to trace also the buffer calls, because BADI database tables are buffered. (Especially view V_EXT_IMP and V_EXT_ACT)

Push the button "Activate Trace". Start transaction VA02 in a new GUI session. Go back to the Performance trace session.

Push the button "Deactivate Trace".

Push the button "Display Trace".

The popup screen "Set Restrictions for Displaying Trace" appears.

Now, filter the trace on Objects:

• V_EXT_IMP

• V_EXT_ACT

Push button "Multiple selections" button behind field Objects

Fill: V_EXT_IMP and V_EXT_ACT

All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BADI class interfaces. The BADI name is after the IF_EX_.

So the BADI name of IF_EX_CUSTOMER_ADD_DATA is CUSTOMER_ADD_DATA

3. Go to “Maintain Transaction” (TCODE- SE93).

Enter the Transaction VD02 for which you want to find BADI.

Click on the Display push buttons.

Get the Package Name. (Package VS in this case)

Go to TCode: SE84->Enhancements->Business Add-inns->Definition

Enter the Package Name and Execute.

Here you get a list of all the Enhancement BADI’s for the given package MB.

Hi,

To create a BAdI follow the following steps:

1) Hope at this point you already have the BAdi definition name with you for the partcular txn.If not then to get the name of the BAdI definition follow the steps as given below:

a)To check for BADI in a particular transaction go to SE24 and enter object type as CL_EXITHANDLER.

b) Then double click on method - GET_INSTANCE.

c)Then put a break-point in the line CASE SY-SUBRC.

d)Then execute your transaction.

e) When it stops at the break-point check the value of the field 'exit_name'.This will give you the name of the BADI definition.

2) Once you have got the BAdI definition name you can get the details about it in txn SE18.

3) To implement the BAdI go to txn SE19. Let us take the eg.MB_MIGO_BADI.

In SE19 enter the implementation name say y_migo_badi.Press create and then enter the definition name 'MB_MIGO_BADI' in the popup that comes.

Then enter a short desc. for it and save and activate it.

4) Then double-click on the particular method say POST_DOCUMENT in this case .Then in the ABAP editor you can put your source code.

5) You can click on the signature tab to check for the parameters.This will give you the import/export parameters. In this case IT_MSEG & IS_MKPF are the parameters.You can use the values to put your code as per requirement.

Hope this helps you.

Pravat.
