The use of object orientated code within SAP has lead to new method of enhancing standard SAP code called Business Add-Ins or BADI's for short. Although the implementation concept is based on classes, methods and inheritance you do not really have to understand this fully to implement a BADI. Simply think of methods as a function module with the same import and export parameters and follow the simple instructions below.

Steps:1. Execute Business Add-In(BADI) transaction SE182. Enter BADI name i.e. HRPBSGB_HESA_NISR and press the display button

3. Select menu option Implementation->Create

4. Give implementation a name such as Z_HRPBSGB_HESA_NISR

5. You can now make any changes you require to the BADI within this implementation, for example choose the Interface tab

6. Double click on the method you want to change, you can now enter any code you require.

7. Please note to find out what import and export parameters a method has got return the original BADI definition (i.e. HRPBSGB_HESA_NISR) and double click on the method name for example within HRPBSGB_HESA_NISR contract is a method

8. When changes have been made activate the implementation

Hi Raghuveer,

Difference Between BADI and Enhancements i.e user exits

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 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-level infrastructure (SAP and customer solutions), but instead allow for a multi-level system landscape (SAP, partner, and customer solutions, as well 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.

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.

GOOD

What is difference between badi and user-exists?

What is difference between enhancements and user-exists? and what is the full form of BADI?

I have another doubt in BDC IN BDC WE HAVE MSEGCALL (i did not remember the > correct name) where the error logs are stored, MSEGCALL is a table or structure.

What is the system landscape?

1) Difference between BADI and USER-EXIT.

i) BADI's can be used any number of times, where as USER-EXITS can be used only one time.

Ex:- if your assigning a USER-EXIT to a project in (CMOD), then you can not assign the same to other project.

ii) BADI's are oops based.

2) About 'BDCMSGCOLL' it is a structure. Used for finding error records.

3) Full form of BADI 'Business addins'.

3) System land scape will be depends on your project

Ex:- 'Development server'~~>'Quality server'~~-> 'Production server'......

THANKS

Hi raghuveer,

1. what are the advantages BAdI's compare to enhance ments

a) Its Object oriented

b) FILTER concept

Eg., in a simple user exit,

u want to do xyz for company code A

pqr for company code B

def for company code C,

then we write

in the same code.

Where as in Badi,

if its design has the FILTER FOR COMPANY CODE,

then we have to write the code separately.

(The badi will automatically call the appropriate code,

for each company code)

c) In badi , we can have MULTIPLE IMPLEMENTATIONS,

ie. We can have MULTIPLE CODES

We can ACTIVATE ANY ONE

at any particular time.

(we don't have to change any code for this)

wherehas , if this was to be done in user exit,

we have to change the code / comment the code, accordingly )
