Hi,

Business add-ins are enhancements to the standard version of the system.

Business Add-In is a new SAP enhancement technique based on ABAP Objects.

They can be inserted into the SAP system based on specific user requirements.

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

In order to enhance a program, a Business Add-In must first be defined

Subsequently two classes are automatically generated:

• An interface with ‘IF_EX_’ inserted between the first and second characters of the BADI name.

• An adapter class with ‘CL_EX_’ inserted between the first and second characters of the BADI name.

The Application developer creates an interface for this Add-In.

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.

hi,

User Exit , is where you change the SAP provided Function module and write your exit.

Customer Exit has been introduced where in you can develop your own FM and add your exit.

SAP exit is the one that provided by SAP.

Customer Exit,

Enables you to determine values for variables by means of Functional Module exit.The function module used is EXIT_SAPLRRSO_001.

Create a project in CMOD by selecting the SAP Enhancement RSR00001 and assign this to the enhanced proj and activate it.

Customer Exit

-

---

SAP creates customer exits for specific programs, screens, and menus within standard applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.

If you want to enhance the functionality of your SAP System, you should take advantage of the exits available in standard applications. There are two main reasons why you should use exits rather than modifying SAP software yourself. Add-ons attached to exits have the advantage that:

• They do not affect standard SAP source code

When you add new functionality to your SAP System using SAP’s exits, you do not alter the source code of standard SAP programs in any way. The code and screens you create are encapsulated as separate objects. These customer objects are linked to standard applications, but exist separately from SAP’s standard software package.

• They do not affect software updates

When you add new functionality to your SAP System using SAP’s exits, your objects (called customer objects) must adhere to strict naming conventions. When it comes time to upgrade a to a new software release, customer objects’ names ensure that they will not be affected by any changes or new additions to the standard software package.

Customer exits are not available for all programs and screens found in the SAP System. You can only use customer exits if they already exist in the SAP System. You find find more information about locating applications with pre-defined exits in Locating Applications that have Exits

Difference Between BADI and 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.

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'......

User exits (Function module exits) are exits developed by SAP. The exit is implementerd as a call to a function module. The code for the function module is written 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_<program name><3 digit suffix>

The call to a functionmodule exit is implemented as:

CALL CUSTOMER.-FUNCTION ❤️ digit suffix>

To find a Exit.

Goto Transaction -- Find The Package

SMOD >f4>Use the Package here to Find the Exits In the Package.

Else if you Want to search by Application Area wise ,

There is one more tab to find the Exits in the Respective Application Area.

Implementing the Exit-- CMOD Create ProjectsAssgn your Component .

Now Run ur Transaction to Check if it Triggers.

Thats it..

Suppose you need to find out all the user exits related to a tcode.

1. Execute the Tcode.

2. Open the SAP program.

3. Get the Development Class.

4. Execute Tcode SE84.

5. Open the Node 'Envir. -> Exit Techniques -> 'Customer Exits -> Enhancements'

6. Enter the Development class and execute.

Check out this thread..

1. Type the transaction : system->status-> <PROG. NAME>

2 open SE37 , type EXIT<PROG NAME> and press F4 to get the list of function exits available.

3. Open CMOD utilities->SAP enhancements

EDIT->All selections

4.type the function module name obtained in step 2, in fields 'component name' in 'additional selections' block. and execute.

5. The displayed list contains the enhancements names for the transaction You were looking for.

6. Create a project in CMOD and the code in default include->activate.

http://www.erpgenie.com/sap/abap/code/abap26.htm

which gives the list of exits for a tcode

1. Previously there were only user-exits.

2. Then came the concept of customer-exits.

3. user exits were nothing but subroutines

FORM/PERFORM

called from standard programs.

4. The FORM defintion was placed inside

an empty include file.

5. So It was called EVERYTIME.

and we need to MODIFY/REPAIR the

standard include .

6. Then it came with concept of customer-exit

7. It consists of calling a FUNCTION MODULE,

which is called only if

the user-exit is ACTIVATED (other wise not called)

In this case, the code in put inside

a pre-defined Z include.

8. Functionality of both is same, howerver

we can note the following important differences

a) Customer exit is called only if activated.

(hence, it does not waste resources)

b) in customer exit, REPAIR does not happen

to the standard include.

Hi,

BADI(Business Add-In) is the object oriented method of user exits...

Each BAdI has a definition and more than one implementation. The definition means the methods(in class concept) that are used for performing various functions. The BAdI definition can be viewed in SE18 transaction(for standard ones) and user-defined BAdIs can be created in the same transaction as well.

When you create a BAdI definition, an class interface will be automatically created and you can define your methods in the interface. The implementation of the methods can be done in SE19 transaction

User exit - A user exit is a three character code that instructs the system to access a program during system processing.

SXX: S is for standard exits that are delivered by SAP. XX represents the 2-digit exit number.

UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number

Customer exit - The R/3 enhancement concept allows you to add your own functionality to SAP’s standard business applications without having to modify the original applications. SAP creates customer exits for specific programs, screens, and menus within standard R/3 applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.

The program for transaction VA01 Create salesorder is SAPMV45A

If you search for CALL CUSTOMER-FUNCTION i program

SAPMV45A you will find ( Among other user exits):

CALL CUSTOMER-FUNCTION '003'

exporting

xvbak = vbak

xvbuk = vbuk

xkomk = tkomk

importing

lvf_subrc = lvf_subrc

tables

xvbfa = xvbfa

xvbap = xvbap

xvbup = xvbup.

The exit calls function module EXIT_SAPMV45A_003

Development

Creating a Project to include the enhancement

1. Go to transaction CMOD and create a project.

2. Enter a description for the project. Then, click on the pushbutton ‘Enhancement Assignments’ in the Application Toolbar.

3. Enter the name of the enhancement and Save.

4. Go to ‘Components’.

Creating Custom Include for ANLU

The screen shown below will appear, showing all the enhancement components under the assignment AIST0002. Double-click on the name of the Include Structure to create it.

Create the include structure with three new fields, as required. Then, save and activate it.

Develop the subscreen and the program

Go to transaction SE80. For the function group XAIS, create a new subscreen 9000.

Create it as subscreen.

Then, go to the Layout of the screen and create three new fields from Database table ANLU.

Drag the fields in the screen body and place them.

Then, save and activate the screen and come back to screen flow editor.

Create the PAI module to add validation for field “Location 2”, as required .

Activate the whole function group and come out.

Write code in the Function Exits to synchronize the programs

Now, code has to be written in the function modules EXIT_SAPLAIST_002 and EXIT_SAPLAIST_003 so that data flows to and fro between the main SAP program and custom subscreen program. For that, go back to transaction CMOD and change the function exits.

Write code in the function module EXIT_SAPLAIST_002 called once at the beginning of the transaction:

Write code in EXIT_SAPLAIST_003 to pass the data from the subscreen to SAP main program.

Then, activate everything – the whole project and come out.

Complete the configuration to link the subscreen

The development portion is complete. Now, linking of the subscreen has to be done with the subscreen area of the main program. In most of the cases, this linking can be done in the enhancement itself. But, here, requirement is a bit different. It is done by configuration using SPRO.

Assets are created under Asset class. And for each asset class, there is a layout assigned to it. For a layout, there are multiple tab pages assigned to it. And, for each tab page, there are multiple screen groups/field groups assigned.

Here, the requirement is to create these three custom fields in the tab page ‘General’ of asset master screen ( AS01/AS02/AS03/AS91).

Determine the Layout

To achieve this, first of all, we need to find out which layout is assigned to asset class 1000.For that, go to transaction AOLK( information has to be obtained from functional consultant).Select the Asset Class ‘1000’ and click on folder ‘General Assignment of Layout’.

Here, for Asset class 1000, for all the user groups, tab layout SAP is assigned. Since layout ‘SAP’ cannot be changed, it has to be copied and manipulated to include our screen group. Later, the new layout has to be assigned over here.

Create new tab layout

Go to transaction AOLA. Copy the tab layout ‘SAP’ to create another layout, say, YSUB.

System will copy all the settings and will inform you about that.

Select your newly created layout and double-click on the folder ‘Tab page titles’.

You want to put your custom fields in the tab page “General”. So, select this tab page entry and double-click on the folder "Position of Groups".

Here, all the field groups currently residing in the tab-page “General” are shown. Add an entry for your newly created fields.

Select the group box from the list. An entry will come with “U” padded with the custom subscreen prepared by you.

Then, save and come out.

Assign the new Layout to Asset Class

Now, go to tcode AOLK and assign tab layout YSUB for asset class 1000.

Save and come out.

Test the Exit

Everything is over. Now, go to transaction code AS01/02/03 or AS91 to deal with an asset of asset class 1000. You will see your new fields added to the screen. Add values to them…save. Then, enter into the tcodes again to see whether the values entered by you are being displayed or not.
