Hi Manmeet,
Differnce Between Customer & User Exits
In contrast to customer exits, user exits allow developers to access and modify program components and data objects in the standard SAP System. On upgrade, each user exit must be checked to ensure that it conforms to the standard system.
There are the following types of user exit:
User exits that use INCLUDEs -
These are customer enhancements that are called directly in the program.
User exits that use tables -
These are used and managed using Customizing.
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 SAPs 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 SAPs standard software package.
· They do not affect software updates
When you add new functionality to your SAP System using SAPs 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
User Exits:
User exits allow you to add additional functions to the SAP standard.
Programs with user exits contain subroutine calls at certain points in their syntax that are identified by the prefix USEREXIT. The actual user exits are located in an include that has been assigned to a module pool. This is where customers can include any changes (enhancements) that they want to make to the system. These includes are always processed during program flow.
Advantage: In principle, customers can modify anything they want that is found in the include (tables, structures, and so forth).
Disadvantage: SAP cannot check the individual enhancements themselves which often leads to errors in the enhancement process.
Types of Exits.
1)MENU EXITS
2)FUNCTION EXITS
3)TABLE EXITS
4)SCREEN EXITS
5)KEYWORD EXITS
6)FIELD EXITS
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.
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.
screen exits:

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.
In 4.6c, you can use "RSMODPRF" program to create field exits.
Screen exits:

Questions about authorization variable customer user exit

Dear all,
To reduce the authorization maintenance effort, I found from the web that we can use authorization variable with customer user exit RSR00001.
When I use the transaction CMOD to display the maintain the user exit RSR00001, the user exit does not found. I would like to know how can I use thie user-exit?
My SAP version is R/3 4.7
The information of authorization variable from web is as follow:
http://help.sap.com/saphelp_nw04/helpdata/en/6d/58f438114ee836e10000000a114084/frameset.htm
Would anyone have some ideas to solve my questions?
Many thanks

Dear Bala Duvvuri,
Firstly, many thanks of your reply.
Actually, what I want to do is to call some user-exit when performing authorization checking. I want to add some logic to the authorization checking and the user exit can be called automatically when performing authorization checking.
I mainly use this checking in the FI module.
Are there any ways I can perform this checking?
One more findings, I have another machine containing SAP XI, I can search the user exit RSR00001. but it doesn't exit in SAP R/3 4.7. Is it version issue or my SAP R/3 4.7 doesn't contain the BI module?
Many Thanks again.
Sunny

Difference between bex user exit and macros in functionality?

Hi all,
I need to create a report on material master data. I created an infoset on 0material and 0mat_plant. In the requirem
ent, I have a report containing different material numbers followed by attributes in each row. the final column in each
row should be calculated using logic. the logic involves comparing different row values and arrive at final conclusion.
the logic comprises of large number of if conditions. so should i use bex user exit or excel macros?
what is the difference between user exit and macros in funcitonalilty?
is there an issue transporting the macro to Prod for end users to use?
any performance criteria?
Any how to documents ..will be of a lot of help
plz send them to [email protected]

Hi,
Macros offer a powerful and flexible way to extend the features of MS Excel. You can either create a macro using VB code or Record a macro. Use Alt+F11 for creating macro using VB code.
You can refer to Microsoft help site or this link for more details:
http://www.taltech.com/support/sw_tricks/exmacros.htm
User-exits are empty subroutines that SAP Developers have provided for you.You can fill them with your own source code.Technically this is a modification.Customer exits are nothing but a include in customer name space will be provided in the function module which starts with CALL CUSTOMER.You can fill them with your own source code.Technically this is an enhancement.
look into following links for procedure to find and use user-exits transaction for finding user-exits is 'SMOD'

Block the customer user EXIT

dear sap gurus
is there any user exit can enable us to block the customer (XD05) when using a specific document type
EXAMPLE:When using a document type X trigger transaction (XD05)

Hi,
Donot use call transaction in any of the user exits or badis
I will give you an idea but not the source code. Find a suitable exit or badi for transaction F-02 or FBZG ( as per your requirement ) . In the exit use class CMD_EI_API method MAINTAIN_BAPI and populate the values as required
for blocking/unblocking customer. Thiswill only get executed when a commit work is invoked by the transaction.

Custom user exit

can we develop our own User Exit

Hi,
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.

BAdi vs. User Exit

Hi,
I was exploring the world of BAdi's and its use. I went thru its documentation on help.sap.com.
But I still could not understand completely its advantage over customer exits. I mean why should I opt for BAdi over Customer exit?
Regards,
Vikrant.

Hi,
Hi
BAdi & Customer-Exit
Though there a different enhancement technique, BAdi has following distinct features
-Uses Object oriented approach
-Two parts - Definition and its Implementation - definition can either be SAP provided or user may also create it
-no longer assumes a two-system infrastructure (SAP and customers)
-allows multiple levels of software development (by SAP, partners, and customers, and as country versions, industry solutions, and the like)
There is not much difference between a user exit and a BADI from a functional stand point. Both of them give us options write custom code that will fire in between the standard code. However, the way these have been implemented differ.
One is implemented using function modules / includes (user exits) and the other one using classes and methods (BADI's).
The best way to find out which user exit to use will be look at the parameters that are accessible and see if they contain the data that you are looking for. You can always put a break point and see if they are firing at the point where you require them.

SImha

User exit info

will someone guide me on usage of USER-EXIT ,
FUNCTION-EXIT & how to use them ? what all things i
have to do initially ? what transaction i have to use
for starting these EXITS?

USER EXITS->
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_<program name><3 digit suffix>
The call to a functionmodule exit is implemented as:
CALL CUSTOMER.-FUNCTION <3 digit suffix>
http://www.sap-img.com/abap/a-short-tutorial-on-user-exits.htm
CUSTOMER EXITS-> t-code CMOD.
As of Release 4.6A SAP provides a new enhancement technique, the Business Add-Ins.
Among others, this enhancement technique has the advantage of
being based on a multi-level system landscape (SAP, country versions, IS solutions, partner,
customer, and so on)
instead of a two-level landscape (SAP, customer) as with the customer exits.
You can create definitions and implementations of business add-ins at any level of the system landscape.
To unify enhancements of the SAP Standard you can migrate customer exits to business add-ins.

In order to find out the user exits for any tcode,
1. get the developement class of the tcode from SE93.
2. Now goto transaction SMOD and press F4,
3. give in the Deve class in the dev class and Press ENTER
this will show u the exits for any tcode.
or execute this report
http://www.erpgenie.com/sap/abap/code/abap26.htm
which gives the list of exits for a tcode

Instead of user exits?

Is there any other method to meet the customer requirements instead of User Exits?

Hi,
BADIs is other method to meet the customer requirements instead of User Exits
i will explain the difference between USER EXIT and BADI.
The major difference between Badi and customer user exit is badi can be built by class and methods means its purely relates to OOPS (Object oriented) and with single badi can contain multiple methods, so that one badi can contains screen, field, function exits.
For BADI:
Suppose let say imepl1 has created for badi00 and this badi00 contains 3 methods, in which you activated one method. Now you can also create one more implementation say imepl2 has to be create for badi00 to be use for method 2.
Conclusion: One BADI can implement multiple times but not Customer exit of project.
And coming to customer user exit, I will explain scenarios
There is requirement you need to be use the enhancement or function exit which already activated under one Project name.
As you know one project can contains multiple enhancements and enhancement also contains multiple function exits.
1) Suppose if you are going to be add one more enhancement in existing project which already implemented by some one. Now you have to go to existing project and go to Enhancement assignment and click on change mode, add new enhancement then by default it will display all function exits which it contains. Then as you know to add the code into include under particular function exit and activate include and come back and press activation button under enhancement screen and come back to initial screen ie CMOD screen press active button. This is one way to active or implement the existing project by multiple times.
2) second scenario is suppose if enhancement contains multiple function exits out of one user exit already activated by some one of written some code. Now you need to be writing or use other function exits under the same enhancement of same project. In this case you cant activate the function exit under separate project instead you need to be use the same project, by writing code in particular include by create it. This is one way you can use the same project as well as same enhancement, but creating or activating new function exit.
3) Third scenario is if you want to add the code to the existing function exit. Suppose if some one else already activated one function exit with code. Now requirement has come to add some more functionality to the same exit under the same enhance, and same project. This is like modifying the existing report or program.
Conclusion: You cant activate one enhancement under two projects
 Reward with points if helpful.

IPC Pricing with AP 7.00 Database Access/Call function module user-exit

Hi experts,
we are running SAP ECO on SAP ECC 6.0 with IPC Pricing AP 7.00 running in the VMC.
I'm facing a new requirement. In an user-exit for requirements the access to the ABAP database is needed.
(I know that the SAP recommendation is, don't have access to database. But we need this functionality)
In ABAP it looks like:
select single * from a590
 into LH_674_a590
 where kappl = 'V'
 and kschl = 'ZSPR'
 and kunnr = komk-kunnr
 and matnr = komp-matnr
 and datbi >= komk-prsdt
 and datab =< komk-prsdt.
Is there a possibility to implement the same SELECT in the Java-User-Exit?
Is there maybe the alternative to call a function module instead?
The database exits on the same application server on which the VMC runs.
If there is a possiblity can anyone provide me with sample coding or give an advice where to find samle coding?
I would prefer to call a functions module.
Thanks in adcance

Hi Shanto & Sumit,
Thanks for the inputs.
as per my understanding of the log

error is thrown by the SAP standard user exit and because of which execution is failing in customer user exits and surprisingly we have not made any changes in both of them.
this was working earlier before upload.could this be because of the jar packaging.
how i can download the standard user exit com.sap.leasing.pricing.tools.LeasingPricingTools from crm
for further investigation.
Thanks,

Sales Order - user exit at item level

I am new in writing user-exits. Pls do share your exp !
When creating a sales order I encounter error, system says "Enter batch number".
We basically create batch when doing GoodsReceive for Production Orders. At this time the Material Revision is copied as Batch into MCHB table.
For example:
Material ABC has the below,
Rev    Batch
A        A
B        B
C        blank
If I create a SO for part ABC for Rev C, it does not allow me becos batch does not exists. But my SO should be allowed to be copy C into the batch field in VBAP.
Pls let me know if we must create custom user-exit rather than modifying std.SAP user-exit for Sales Order processing (MV45AFZZ).
Is there any contraints using the batch field in SO? As I came to know that the problem is when creating a Purchase Order it allows to enter free text in batch field but SO doesnt allow. Is't?
Is there any standard way to config the system such that SO will bypass the existence checking of the batch
Pls share !
Pri

Hi, but inplace of Batch we only enter the Revision of the material. Becos rev-batch relationship is 1-1, meaning is rev is A, the batch will be A too.
We just use the batch field to represent the revision
Rev    Batch
A        A
B        B
C        blank
I can enter A in SO item batch field because system check that batch A exists
I can enter B in SO item batch field because system check that batch B exists
But I cant enter C in SO item batch field because system check that batch C doesnt exist
Wondering how the system might know the batch is actually my revision. Not sure if I use User EXIT to move C into VBAP-CHARG, will it give me error message because it will find out that there is no C batch
Your views !

BADI/User exit for MIGO fi postings

Hello Experts,
I have one requirement regarding at the time of MIGO accounting entry is generating based on the OBYC settings,now the client want along with this entry, want to create one more FI document through background,In the background we will give the debit g/l and credit g/l.That means at the time of MIGO two FI documents has to generate one is with OBYC setting gl's and second FI entry is from programe hard coded gl's.
For this requirement has any BADI/USER Exit.I appriciate your valuable inputs.
Regards,
Nivas.

Hi,
May I know why you need two accounting documents?
You may refer the similar thread: BADI / Exit required for MIGO for posting FI document
And about the number ranges - I would suggest a custom number range object and a different number range for these additional documents.
Also refer the doc: Methods to find Customer/User Exit's & BADi's for a Transaction Code!

SAP ISU - User exits at the end of move-in process

Hi,
We have a requirement to send some outbound messages on completion of Move-in process in SAP ISU system. And send some outbound message on completion of Reverse Move-in process.
I tried to find the customer/user exit in transaction EC50E and EC53E, all i could find is user exits during the process. I need something at the end of process.
At the moment all I can do is use the events raised when these process are completed (Ex: MOVEINDOC.Created) and start a workflow to send outbound messages. But i would want to know if there are any exits available at the end of the processess as I dont want to create a workflow just for one activity.
Any inputs will be appreciated.
Many Thanks,

Code Review of User Exits with Code Inspector

Hi,
We are using Code Inspector(Tcode - SCI) for checking the quality of ABAP Codes. It is working fine for all custom programs. But when we are checking the code of User Exits i: e MV50AFZ1 or ZXM06U22 then it checks the std SAP program (SAPMV50A) or (SAPLXM06) for these exits in place of checking that particular Exit only . How the customer/User Exits can be checked using Code Inspector. Pls advice.

Hi there!
Today, I stumbled over the same problem: Defining an Include for user exits leads to a check of the surrounding function group from SAP which I don't want to correct at all.
Is there a nice an elegant way of filtering out the SAP modules from checking? If not, the only way to get around this seems to be building an own implementation of the Code Inspector integration into CTS.
Thanks, Markus

User Exit issue after upgrade from 4.6c to ECC 6.0

Hi Experts,
After upgrade we are facing some issues regarding user exit. In 4.6c we have implemented several user exit to do customization in several module like SD,FI and HR. But after upgrade it has been identified that SAP has already provided this functionality in ECC 6.0. Now our problem is when this transactions are called or executed control is going to both custom and standard code. Which took long time to execute and causing performance issue.
Is there any ways to identify which are the functionality SAP has provided in ECC 6.0 so that we can delete our custom user exits.

Hi
List all the user exits which you have modified and check in OSS notes you will get the OSS note with all the details what functionality has been changed. Based on this you can delete or retain the user exits which ever you want.

JB

Can the user exit EXIT_SAPMM07M_004 be called from an FM exit in my code?

Hi ,
When I create a Goods Receipt by tx MB1C , an MM adapter(FM user exit) is kicked off in my workspace creating documents wrt to that goods receipt.However if a batch does not exist during MB1C , it says that a batch would be created.But when i do a save , the user exit is kicked off before it returns to the SAP code to create a batch.As a result no MM documents are created in my workspace.Now I want that the batch be created while in my user exit and I want to implement the customer user exit EXIT_SAPMM07M_004(for copying the batch characteristics) .Is it possible to call this exit from my code?Kindly suggest.

Can you call the user exit? - Yes ofcourse.... but why dont you just add the same code that is in your exit instead of calling the user exit?
User exits are developed and called from appropriate places where sap can take the changes and apply to the transaction. there is no restriction on calling the user exit (atleast programmatically) but you need to think 100 times before you call the user exit.
For example, you want to call user exit 'A' in your program because you want to use the code in this user exit in your program '1'. Why dont you just write the code in program '1' with what is in user exit 'A' ?
Calling user exit in your program does not really helps. Better find out different ways. once again, user exits are embedded in sap business applications and remember they are not independent FM's as you think
Good luck
