Sir

Difference between BAPI and BADI?

BAPI - Business Application - commonly a function module that is normally RFC enabled as well and acts as a method of a business object. For example, Sales Order as the business object with a method of create - the BAPI is BAPI_SALESORDER_CREATEFROMDAT2.

A BADI is a Business Add-in - one of SAP's methods of implementing a user-exit or change to standard SAP code. BADI's are ABAP object based changes instead of the more common subroutines/function modules.

Hi,

BAPI (Business Application Programming Interface) :

BAPIis an API method of a business object which intern is a RFC enabled Function Module.

Business Objects are the Objects which has business sence associated to it. Ex. Sales Orders, Purchase Orders etc.

The Properties of BAPI are:

Every BAPI name should start with letters 'BAPI'.

It is an API method of a Business Object.

it does not contain a internal COMMIT statement in the Function Module.

It does not contain "CALL TRANSACTION" statements.

BAPI do not raise 'EXCEPTIONS'.

a RETURN structure is defined as an interface parameter of a BAPI which is used to log all the errors, warnings and the successful processes tha are triggered in the course of execution of a BAPI.

A successful execution of a BAPI requires the data to be commited and this process of performing a COMMIT is achieved by calling the BAPI_TRANSACTION_COMMIT' explicitly if there are no errors logged in the RETURN structure.

There are two types of BAPI's: Instance Dependent & Instance Independent.

BAPI provides an access to the SAP system for external applications to have the business data processed in the form of web services. When BAPI's are used to post the data in SAP system these are used as Function Modules.

BADI

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

Badi’s allow for a multi-level system landscape (SAP, partner, and customer solutions, as well as country versions, industry solutions, and the like).

Business Add-Ins can be created at each level within such a system infrastructure

Some BADI can have multiple independent implementations which is much better for software deployment as several developers can implement the same BADI independently.

1} Identify the User Exit suitable for the requirement and that is available in the system:

Code SE18 is used to Identify the BADI available.

Look for the string 'CL_EXITHANDLER' in the standard program. This is a class which has a method 'GET_INSTANCE' which is used to trigger BADI's from the Standard Program. The interface parameter for this static method 'EXIT_NAME' is used to pass the BADI to the method.

Open Standard Program and do a global search 'CL_EXITHANDLER'.

SE18 > give the BADI name found through above search.

CUSTOMER_ADD_DATA > which has a method SAVE_DATA.

2} Implement the User Exit identified through above process.

T.Code SE19 is used to Implement BADI.

SE19 > give the implementation name > Give the Definition name as CUSTOMER_ADD_DATA and the Short Text.

Business Add-Ins

Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.

As with customer exits (SMOD/CMOD [Page 40]), two different views are available:

• In the definition view, an application programmer predefines exit points in a source that allow specific industry sectors, partners, and customers to attach additional software to standard SAP source code without having to modify the original object.

• In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard logic if one is available.

In contrast to customer exits, Business Add-Ins no longer assume a two-system infrastructure (SAP and customers), but instead allow for multiple levels of software development (by SAP, partners, and customers, and as country versions, industry solutions, and the like). Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.

SAP guarantees the upward compatibility of all Business Add-In interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces. You do not have to register Business Add-Ins in SSCR.

The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time.

In addition, Business Add-Ins can be defined according to filter values. This allows you to control add-in implementation and make it dependent on specific criteria (on a specific Country value, for example). All ABAP sources, screens, GUIs, and table interfaces created using this enhancement technique are defined in a manner that allows customers to include their own enhancements in the standard.

A single Business Add-In contains all of the interfaces necessary to implement a specific task. In Release 4.6A, program and menu enhancements can be made with Business Add-Ins. The actual program code is enhanced using ABAP Objects. In order to better understand the programming techniques behind the Business Add-In enhancement concept, SAP recommends reading the section on ABAP Objects

DEFINING THE BADI

1) execute Tcode SE18.

2) Specify a definition Name : ZBADI_SPFLI

3) Press create

4) Choose the attribute tab. Specify short desc for badi.. and specify the type :

multiple use.

5) Choose the interface tab

6) Specify interface name: ZIF_EX_BADI_SPFLI and save.

7) Dbl clk on interface name to start class builder . specify a method name (name,

level, desc).

Method level desc

Linese;ection instance methos some desc

😎 place the cursor on the method name desc its parameters to define the interface.

Parameter type refe field desc

I_carrid import spfli-carrid some

I_connid import spefi-connid some

9) save , check and activate…adapter class proposed by system is

ZCL_IM_IM_LINESEL is genereated.

IMPLEMENTATION OF BADI DEFINITION

1) EXECUTE tcode se18.choose menuitem create from the implementation menubar.

2) Specify aname for implementation ZIM_LINESEL

3) Specify short desc.

4) Choose interface tab. System proposes a name fo the implementation class.

ZCL_IM_IMLINESEL which is already generarted.

5) Specify short desc for method

6) Dbl clk on method to insert code..(check the code in “AAA”).

7) Save , check and activate the code.
