Hi

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.

which gives the list of exits for a tcode

Also please check these threads for more details about user exits.

1. Document on UserExits in FI/CO

2. Finding User Exits...

3. List of all User Exits...

http://www.planetsap.com/userexit_main_page.htm

1. Customer exits: Implemented as Function Modules within z includes. Anybody can change it and no access key is required.

2. User Exit: Implemented as subroutines within includes (any include except y or z includes). You need access for the specific include and then you can any subroutine (user exit) within that Include.

BADIs are the enhanced version of user exits where the same logic is implemented via classes and object (OOP)

Enchancement point is the latest once introduces with ECC6.0 . Not very sure about that but you can change it without any access key.

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.

Exits are basically the hooks whcih SAP has provided to add your own code.

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.

Now write a sample program to use this badi method..

Look for “BBB” sample program.

“AAA”

data : wa_flights type sflight,

it_flights type table of sflight.

format color col_heading.

write:/ 'Flight info of:', i_carrid, i_connid.

format color col_normal.

select * from sflight

into corresponding fields of table it_flights

where carrid = i_carrid

and connid = i_connid.

loop at it_flights into wa_flights.

write:/ wa_flights-fldate,

wa_flights-planetype,

wa_flights-price currency wa_flights-currency,

wa_flights-seatsmax,

wa_flights-seatsocc.

endloop.

“BBB”

REPORT ZBADI_TEST .

data: wa_spfli type spfli,

it_spfli type table of spfli with key carrid connid.

*Initialise the object of the interface.

data: exit_ref type ref to ZCL_IM_IM_LINESEL,

exit_ref1 type ref to ZIF_EX_BADISPFLI1.

selection-screen begin of block b1.

start-of-selection.

select * from spfli into corresponding fields of table it_spfli

where carrid in s_carr.

end-of-selection.

loop at it_spfli into wa_spfli.

write:/ wa_spfli-carrid,

wa_spfli-connid,

wa_spfli-cityfrom,

wa_spfli-deptime,

wa_spfli-arrtime.

hide: wa_spfli-carrid, wa_spfli-connid.

endloop.

at line-selection.

check not wa_spfli-carrid is initial.

create object exit_ref.

exit_ref1 = exit_ref.

call method exit_ref1->lineselection

EXPORTING

i_carrid = wa_spfli-carrid

i_connid = wa_spfli-connid.

clear wa_spfli.

thank u verymuch anji.

i did one BDC programe, i executed it, but it is taking only one record from flat file.

how can i take second record from flat file.

thanks
