Solved: BADI

Former Member · ‎2006 Dec 07

Hi

If we are going to create BADI'S,SE18 is the tcode for business addins.

I have doubt,here we create interfaces and we assign methods for that.

Do we write the code in this method??or we just define ?and how do we implement this BADI in particulat transaction.

I think we need to write report and we call class etc.

How do we implement in tcode?example i want to add one more field(screen exit)

any tcode(mmo1,va01 etc).how do we proceed with that?

Any exam will be highly appreciated.

Thanks in advance

You can use the transaction SE18 to define a new BAdI definition which may be implemented by other developers later. It is not so challenging. Here is the roadmap:

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,,

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.
