Difference in user exit , fm and includes

HI,
What is user exit , function module and includes? What is the difference among them? When and how to use them? Please provide example.
Regards,
Pramod

Hi Pramod,
user exits, function modules and includes can not be compared to each other. Each one of them carry their own purpose and functionality.
User exit's help you in achieving the additional functionality that standard SAP doesnt offer.
For example, if your client requirement is add another tab in sales order in addition to the existing ones............it can be done using the user exit.
SAP has provided several user exits through which you provide the additional functionality to the client without disturbing the SAP standard code.
you can view SAP standard user exits using t-code: SMOD
Function modules help you in carrying out a specific task. They can be called into a program to perform a particular task and are resuable any number of times i.e. can be called into any program to perform the same task.
SAP has already provided many function modules, for example - for determining exhange rates, reading texts etc.
Apart from the SAP standard ones, you can also develop your own function module using transaction code SE37 and use them appropriately.
Includes can be defined as sub programs.........they are part of a program. Include can either be local or global i.e. can be restricted to be used in a particular program and can be made available to other programs.
Basically, a main program is divided into several includes for a better understanding.

Difference between user exit,enhancement and BAdi

DIfference Between User Exits, Screen Exits, Menu Exits And BADI

Could any one let me know the exact/practical dIfference Between User Exits, Screen Exits, Menu Exits And BADI. ? And why BADIs are more proned to use?

Hi,
User Exits:
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
Menu Exits:
Menu exits add items to the pulldown menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.
SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu items text when activating the item in an add-on project.
Screen Exits:
Screen exits add fields to screens in R/3 applications. SAP creates screen exits by placing special subscreen areas on a standard R/3 screen and calling a customer subscreen from the standard screens flow logic.
BADIs:
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.
And why BADIs are more proned to use?
In contrast to above 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 User Exits and BAPI

hello sap gurus
what is difference between User Exits and BAPIs

http://www.sap-img.com/abap/what-is-user-exits.htm
www.****************
Where as this customer exits are again divided into:
1. Menu Exits.
2. Field Exits.
3. Screen Exits.
4. Function module exits.
These all the things comes under Enhancements.
User exits
1.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
2.USER EXITS are FORMS and are called by SAP standard programs
using PERFORM.
3.Inside the form (user exit) you can read and change almost
any global data from host program.
4. User exits are more flexible because you have more information to use in your code but on the other hand , it is very easy to manipulate erroneously global data and lead the standard program to a dump or even to make database inconsistent.
5.While changing User-exit,Access Key is required,
BAPI is nothing function module but which is remote enabled, means you can access this fm through other SAP or non-SAP system by assingning to business object,which we can crea in SWO1 transaction.

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 SAPs 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. *-- Mani
The following document is about exits in SAP :-
The R/3 enhancement concept allows you to add your own functionality to SAPs standard business applications without having to modify the original applications.
SAP creates user 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.
Types of Exits
There are several different types of user exits. Each of these exits acts as hooks where you can attach or "hang" your own add-ons.
Menu Exits
Menu exits add items to the pulldown menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.
SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu items text when activating the item in an add-on project.
Screen Exits
Screen exits add fields to screens in R/3 applications. SAP creates screen exits by placing special subscreen areas on a standard R/3 screen and calling a customer subscreen from the standard screens flow logic.
Function Module Exits
Function module exits add functions to R/3 applications. Function module exits play a role in both menu and screen exits.
When you add a new menu item to a standard pull down menu, you use a function module exit to define the actions that should take place once your menu is activated.
Function module exits also control the data flow between standard programs and screen exit fields. SAP application developers create function module exits by writing calls to customer functions into the source code of standard R/3 programs.
These calls have the following syntax:
CALL CUSTOMER-FUNCTION 001.
Field Exits
Field exits allow you to create your own programming logic for any data element in the Dictionary. You can use this logic to carry out checks, conversions, or business-related processing for any screen field. Example: The data element BBBNR identifies a companys international location number. You might want to set up your R/3 System so that all international location numbers are larger than 100.
The field exit concept lets you create a special function module that contains this logic.
You assign the special function module to the data element BBBNR. You then assign the module to any programs and screens in which users can add new international location numbers. When you activate your field exit, the system automatically triggers your special routine whenever a user enters a company location number.

User Exit's and BADI's

HI SAP Gurus,
Can anybody please tell me what are user exits and BADI'S, and how are they used.
Thanks in Advance.
Sravanthi

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
The R/3 enhancement concept allows you to add your own functionality to SAPs standard business applications without having to modify the original applications.
SAP creates user exits for specific programs, screens, and menus within standard R/3 applications. These exits do not contain any functionality.
An example of a user exits :-
MODULE user_exit_0001 INPUT
CASE okcode.
WHEN 'BACK OR EXIT'.
CASE sy-dynnr.
WHEN '100'.
SET SCREEN 0.
LEAVE SCREEN.
WHEN '200'.
Note that you can write any code that satisfy your needs. ****
But in this case, this was wrote as a sample code for reference sake. ****
And you can test it. ****
SET SCREEN 100.
LEAVE SCREEN.
ENDCASE.
ENDCASE.
BADI: can be used for multiple implementations
that is the difference between user exit and Badi.
which-ever thing you execute that related code will be executed.
see the Badi's doc
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.
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.

Difference between user exit/Function exit / Customer exit and BADI

Hi Guys,
I am confused with the types of exits-user exit/Function exit / Customer exit and BADI.
Can you tell me the difference between the different exits/Enhancements?
Classify the following:
what is the one which is shown in SMOD under enhancements? There are 3 sections in that - Function module, Screen and includes.
What is the one which are called using -
Call Customer-Function 001?
Regards,
Guru

hi,
The standard applications do not offer some of the functionality you need. The R/3 enchancement concept allows you to add your own functionality to SAP's standard business applications.
Different types of enhancements
Enhancements using customer exits
Customers' potential requirements which are not included in the standard software are incorporated in the standard as empty modification 'shells'. Customers can then fill these with their own coding. Enhancements can relate to programs, menus and screens. Upward compatibility is assured. In other words, SAP guarantees that the jump from the standard software to the exit and the interface which call the exit will remain valid in future releases.
Enhancements to ABAP/4 Dictionary elements
These are ABAP/4 Dictionary enhancements (creation of table appends), text enhancements (customer-specific key words and documentation for data elements) and field exits (creation of additional coding for data elements).
advantages of enhancements
Do not affect standard SAP source code
Do not affect software upgrades
Customer exit - The R/3 enhancement concept allows you to add your own functionality to SAPs 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.
Various types of customer exits
Menu exits
Screen exits
Function module exits
Keyword exits
Menu exit
Adding items to the pulldown menus in standard R/3 applications .
Screen exit
Adding fields to the screens within R/3 applications. SAP creates screen exits by placing special subscreen areas within a standard R/3 screen and calling a customer subscreen from within the standard dynpro's flow logic.
Function module exit
Adding functionality to R/3 applications. Function module exits play a role in both menu and screen exits.
keyword exit
Add documentation to the data elements of key words defined in the ABAP/4 Dictionary. The system displays this documentation whenever a user presses F1 to get online help for a screen field
Hope this helps, Do reward.

What is the difference between User exit and BADI

in user exit support to 4 types of exits(Menu exit,Screen exit,Field exit,Function module exit)in similar way is badi supported to all type

hi,
BADIs (Business Add-Ins) are the new way in which SAP allows you to enter additional logic into an application, and is based on OO ABAP. (Methods in Interfaces) Transactions SE18/SE19.
Customer Exits are the older method (which is still supported), whereby you create an include that is in a function module, which is called when the customer exit is activated. Transactions CMOD/SMOD.
In terms of terminology, people often use the terms "Customer Exit" and "User Exit" interchangeably, however, strictly speaking, User Exits are places provided in subroutines (notably in the SD module) where you can insert your own code, but require a modification to an include (although it is provided for customers to change).
They are two different methods to do the same thing: to check and update the data into std trx.
The user-exit is the old concept based on function module
The BADI is the new concept based on OO ABAP.
So you can often to find a BADI and an USER-EXIT to do the same thing and you have to decide what you prefer to use.
Anyway the new trx and the enjoy trx use BADIs as exit
User-exits are SAP's oldest way of updating data in standard programs - see MV45AFZZ - Form Userexit_Save_Document_Prepare.
Here you simply add ABAP code or add INCLUDES, etc
Customer-exits were SAP's next generation. They are built on the concept of function modules - where you add your custom within the Z func modules.
BADIs are SAP's newest and current way of updating data uisng Object-oriented concepts.

User-Exit is a specific place in a transaction-process where SAP offers
third parties to include there own business functionality. Actually
User-Exit is the namespace used for Exits programmed by SAP specifically
for SD. For the other modules it's called Customer-Exit.=20
>Business Add-Ins (BADI) =20
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.

A/R User Exit Spec and code

The spec -
1.     Canadian tax - currently based on Freight type:   Read the country(?) Ship-from (plant jurisdiction) to Ship-to(customer jurisdiction) and the inco term on the line item of the sales order and if it's not equal to 'DDP' the line item tax classification will be set to '0' exempt. (This is freight that comes into Canada from the US)
We will look at the shipto and shipfrom txjcd on the sales order document and billing document along with the inco term logic and we will tax freight when they are both Canada
Example Scenario:
For Freight charges where the Ship from is in Canada (Bedco, Artmedco, etc) and the Ship-to is in Canada the freight will always be taxable regardless of the inco term. This is freight that ships within Canada, no boarder crossing.
2.     Regular Freight - US & Canada: If separate line item on sales order, it may be exempt from tax based upon state. revisit
a.     D.1 Freight included on the line item
i.     The freight is passed to the external system by populating the field FREIGHT. The freight amount is always included in the base amount.
ii.     An example to fill the freight using the user-exit:
iii.     In the customer pricing procedure (for example ZUSA01) enter 4 in the subtotal field of the freight condition type (OTC must have this configuration in the pricing procedure for the freight pricing conditions).
iv.     In the customer structure CI_TAX_INPUT_USER, add the field KZWI4 as in KOMP-KZWI4.
v.     In the user-exit, add the code CH_USER_CHANGED_FIELDS-FREIGHT_AM = I_INPUT_USER-KZWI4.
3.     For PO Specific A/R Tax Exemptions using material tax class of 2, pass the TAXM1 field to the ACCOUNT_NO field in Taxware
oSolution:
For PO Specific Tax Exemptions CSR will go to the line item detail Billing Tab, Tax Classification field (TAXM1) and change that to 2 One-Time Exemption. Configuration complete.
CSR will go to the Text Tab, Internal Item Notice and CSR will provide a brief description as to why that line is tax exempt.

Difference between User Exit & a Functional Module

Dear all,
Please help me in understanding ,what's an User Exit & a Functional Module in
standard SAP.How do we define both of them.
1.When can/cannot I use an user exit?How to check for which T codes in PP
Module an User Exit can be used or present.
2.Can I use only a Functional Modules for Z developments or also an user Exit for
Z developments?
Please explain it in a simple way.
It will be a great help for me,Expecting for your help.
Regards
Mangal

user exit is a customised code used to extend or change normal SAP functionality.FM is a piece of reusable code uesed as a part of modularisation technique in SAP so that you can use this code again & again.
1. you create FM through se37. First create function group which in return will contain your FM. you creates user exits through SMOD and CMOD. In case of some standard programs there are special includes where you can add u r own code to extend standard functionality. ( in pro sapmv45a include sapmvfzz used).
to find an exit go to se80 or se84 give the package name and find exit corresponding to it ( ex for sales exits give package VA then search for exit )
for second point i didnt get get what u want to know?
for any z development u dont need at all to use exits u can do it thru SE38.USER-EXIT is add on functionality to customise u r standard transaction.
i hope this will clear u r doubt.reward points if helpful.
