HI suneel

For information on BAdI's, you can take the standard SAP course "BC 425 - Enhancements and Modifications"

Here is a summary:

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

That's all. For further details, i.e. filter-dependence, multi-usage, menu nehancements etc... you can have a look at course materials of BC425 "Enhancements and Modifications".

BAPIs are function modules in a simple aspect. The importance of them is lied at their functionality. To inspect BAPIs and business objects use the transaction "BAPI".

BAPIs are taken as topics at several SAP courses.

hi rk,

Thank u very mcuh for ur prompt reply, actually i am in bw, i am week in abap, i have seen previously this procedure, i am unable to understand properly, bec in bw we can export data from bw to another 3rd party tool using export data into external system, badis we can use for tarnsformation. i heared we can use bapi to export data also. ple clarify.

Thanking u

suneel.

Suneel,

In simple words,,,

Bapi's r used to transfer the data between the sap system and different business partner system these r simply remote enabled function modules.. v can accees these bapi's through rfc layer...

Where as in the case of badi's.. if you want to do any enhancements to sap standard programs or application u have to use eithe user exits or badi's...

badi's r especially designed with object oriented concepts.....

i think u got the basic idea if u need further info do lemme know
