Former Member — Mon, 17 Dec 2007 05:59:34 GMT

Hi,

i have some doubts about BADI plz tell me these questions:-

1.What is BADI and how many types of badis.

2.How to implement BADI for particular T'code.

3.What is diff between BADI and User-Exit.

4.what is diff bet ween User-Exit and Customer Exit.

5.How to find out BADI's in one t'code.

6.what is user-exit and how many types of user-exits and how to implement .

Thanks,

Srinivas.

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

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 SE19 is the BADI equivalent of transaction CMOD .

Difference Between BADI and User Exits

http://www.sap-img.com/abap/difference-between-badi-and-user-exits.htm

Rewards if useful.........

Re: BADI

Former Member — Mon, 17 Dec 2007 06:09:35 GMT

User Exits are also called as BADI's (Business Aditions)

There are two steps in User Exit creation.

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.

There are other tutorials on this site...

http://sapbrain.com/Tutorials/tuto_download.html

What are BAdIs?

-> is an anticipated point of extension – these points act like sockets and exist in the original source code

-> based on ABAP Objects. BAdI defines an interface that can be implemented by BAdI-implementations that are transport objects of their own

->Important! There are 2 roles: Enhancement Option-provider & Implementer.

-> In the above context, Enhancement Implementation can be done only if option (hook) is provided by the Option-provider. In simple words there are no implicit BAdIs.

Note: In the following slides, Definitions are created so as to understand the method of BAdI definition & for example purpose. As stated above this is the role of Enhancement Option-Provider.

Classic BAdIs already exist since SAP Release 4.6

BAdIs have been Re-implemented in ECC7.0 under the new Enhancement Framework & Switch Framework

Classic BAdIs

To understand what a powerful pattern a BAdI is, we will now define & then implement a BAdI

BADI Class is created automatically.

The various options are described below in detail:

1. Enhanceable: Enhanceability of filter types can only be specified for filter-dependent BADI definitions under very special conditions. For example, the domain belonging to the filter type must be linked with a value table that is of the type E or G. A BADI implementation can then be created in one step by creating a new filter value that is automatically entered into the value table at save and also copied into the transport order of the BADI implementation. In addition, it is also possible to create a new filter value and, at the same time, a BADI implementation with the same name. Naturally, you can also specify existing filter values.

You should select this feature if there is a prerequisite that a new filter value is created together with a new BADI implementation - that is, that BADI implementations are not created solely with existing filter values, although this, too, is possible.

2. Multiple-Use

3. Filter-Dependent

Instance Methods can access all of the attributes of a class and can trigger all events of a class. Static Methods can only access static attributes and static events.

Exceptions:

Events:

Events can be defined in classes or in interfaces. Corresponding methods can trigger these events with the RAISE EVENT statement. Each class (or interface) that is going to handle the corresponding event must implement a relevant handler method, and register it using the SET HANDLER statement. When an event occurs, the system calls all of the handler methods registered for that event.

Like method definitions, events have a parameter interface. The only difference is that events may only have EXPORTING parameters.

BADI : Businees Add IN's

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

Where the SAP standard program is not going to fullfill the client requirement , we are going to add our own program to SAP standard program, without changing the standard prog.

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

Each BADI has two different Views.

1.Definition view

2.Implementation view

T.C for BADI Definition is SE18.

T.C for BADI Implementation is SE19.

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.
