Hi All,

I'm new for enhancements,can someone tell me after finding the enhancement,where & how should i add my code.

User exits :

1. Introduction:

User exits (Function module exits) are exits developed by SAP. The exit is implementerd as a call to a functionmodule. The code for the function module is writeen by the developer. You are not writing the code directly in the function module, but in the include that is implemented in the function module.

The naming standard of function modules for functionmodule exits is:

EXIT_Execute(F8)

BAdi:

SAP Business Add-Ins (BAdIs) are one of the most important technologies used to adapt SAP software to specific requirements. BAdIs were introduced with Release 4.6 and replace function module exits. This technology is not limited to SAP applications. BAdI calls can be integrated in customer applications. These can then be enhanced by other customer applications. In the various SAP applications, BAdI calls are implemented at places where enhancements are appropriate.Business add-ins are enhancements to the standard version of the system. 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 defines exit points in a source that allow specific industry sectors, partners, and customers to attach additional coding 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 solution, 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, country-specific versions, industry solutions, partner, customer, and so on). You can create definitions and implementations of Business Add-Ins at any level of the system landscape.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 differentiate between Add-In implementations using the filter Country or other criteria.

The enhancement technique is set up in such a way that it is possible to define interfaces for ABAP soure code, screens, GUI interfaces, and tables. These allow 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.

BADI is just an object-oriented version of user-exit. Instead of entering program code into some function module (as in customer-exit), you define some class which has to implement predefined methods and those methods are fired at predefined points just like an old user-exit. Some BADI can have multiple independent implementations which is much better for software deployment as several developers can implement the same BADI independently. BADI/UserExists are used to enhance R/3 For customer Needs.

Actually there is no transaction to find when and where the BADI

is called.

1. You can see the BADI description to find why it is called.

2. Once you implemented and activated the BADI, put some break points

in the BADI and see "where else used" option to check in what all

programs this BADI is called. In the ITS debug, when you are doing

the operation what exactly the BADI description tells, it will take

to the break points and you have to do manually debug the whole thing.

I know its bit difficult to do manual debug the whole thing, it

takes lot of time, but you have to be very patience when you are

dealing with BADI's.

Transaction SE18 is the BADI equivalent of transaction SMOD

Transaction SE19 is the BADI equivalent of transaction CMOD .

To find the BADI to be implemented and then implement this via SE19.

These steps should enable you to find any BADI related to any transaction in a matter of minutes.

Procedure 1:

1) Go to the transaction SE37 to find your function module.

2) Locate the function SXV_GET_CLIF_BY_NAME.

3) Put a breakpoint there.

4) Now open a new session.

5) Go to your transaction. 6) At that time, it will stop this function.

7) Double click on the function field EXIT_NAME.

😎 That will give you name of the BADI that is provided in your transaction.

Business Add-Ins

Procedure 2:

1) Goto se24 (Display class cl_exithandler)

2) Double click on the method GET_INSTANCE.

3) Put a break point at Line no.25 (CASE sy-subrc).

4) Now Execute SAP standard transaction

5) Press the required button for which you need to write an exit logic, the execution will stop at the break point.

6) Check the values of variable 'exit_name', it will give you the BADI name called at that time.

7) This way you will find all the BADIs called on click of any button in any transaction

To find the BADI to be implemented and then implement this via SE19.

Hi Sravan,

Thanks for ur reply,I've got stuck in double clicking the Include ZXVVAU04.I'm getting a message "Program names "ZX" are reserved for includes of exit function groups"

Dont know how to proceed.

Hi Kavitha,

First double click the Include ZXVVAU04. then a message will come "Program names "ZX" are reserved for includes of exit function groups".

Now press the enter straight away.

and you will be prompt to create the include.

Reward if helpful.
