How to see function exit Z_STRUCTURE_MAPPER_AFTER

Hi,
PROBLEM:I want to find out where and How function exit is called in my program.
I have one program that will load Temporary table entry to Permanebt table in MW.
Program Z_ASCI_ADAPTER_INVOKE is calling customer exit Z_STRUCTURE_MAPPER_AFTER
to map some field while loading data from temp table to permanent(Consolidated database) table.
Can any one please tell me how it is calling in my program.
Even after debugging the program I am not able to find out where exit is called.

Hi Amit,
I would suggest to display the function in SE37 (or in SE38 if it is a program) and then use the 'where used' button.
best regards
Christophe

How to see user exit code

hi,
i have one user exit name with me like EXIT_SAPLVxxxxx. how can i see it's code.
thks

Those user exits are build as function modules. Just goe to transaction SE37, put in the name and there you go. Double click on the include in the FM and you'll see the code. If the include doesn't exist this user exit has not yet been implemented.

Writing function Exits

Hi All,
 I m very much interested in knowing how to write function exits in BPS. Can any body pls explain me how to write them step by step.
 Pls suggest me some very good documents on this.
 Is there any standard exits given by SAP? If so pls tell me the names of those exits.
Regards,
Ramana.

Hi Ramana,
the first (Init) FM has to be used if you need to perform some actions only once before any other operation. In this "how to" doc you read the input file.
About this FM SAP says:
"This function module is optional. It is only required if new transaction data records are to be generated in the planning function that are different, in terms of the combinations of values, to characteristics in the previous transaction data that are not to be changed. The keys for these new transaction data records are delivered by the function module in the table ETO_CHAS. The keys are supplemented by the keys of the transaction data that already exist. The data objects for which the planning function is called up are formed from these keys. They also influence how often and with which combinations of transaction data the second function module is called up."
The second FM is executed many times and in this "how to" is used to write data: you can easily get that it moves data read from the input file xth_data.
About SAP says:
"A function module that is called up several times and that changes transaction data records. This function module receives a package of transaction data records in each case. These differ only in their characteristics to be changed. They have the same values as far as all other characteristics are concerned. The transaction data is in table XTH_DATA. Only the existing records are transferred. If key combinations were returned by the initialization function module, and no transaction data exists for these, then table XTH_DATA is empty. The key combination is in the table ITO_CHASEL."
Generally you have to implement the second FM (mandatory) that performs calculations on xth_data table: implementing the first (optional FM) depends on your business requirements.
Hope it helps

How to run function(s) on ANY program exit?

I can easily do this when someone selects "Exit" from the program's menu, with this code:
AllSortsOfExitCode()
System.out.println("Ok, everything is wrapped up. Now we will end the program.");
System.exit(0);
BUT...how do you get this code to run when someone clicks the little X in the upper-right hand corner?
I can't figure out how to do that.
I need to override the class destructor or something, but I don't think Java has destructors in the classic sense. I found one 4-page thread about "Java destructors" but it was just an argument between a couple people -- I didn't learn anything from it.
Thanks,
Matthew

Hi friends,
I have a requirement, where in i am creating a screen exit for ME51N.I am using MEREQ001 enhancement for this.It is working fine, but i am to get data in to this so as to write any code.For that i am using the function exit EXIT_SAPLMEREQ_001 in that same enhancement(thought of doing export and import).
But the data is declared in this way..

How to find function module exit name when i know the Include

As per my requirement i should change the existing exit. I know the include name but i want to
know exit name. How to find out exit name based on include name. I tried Where-used list but it
is not giving the exit and function module name.Please let me know.
Regards
Rajitha

Hello Rajitha,
1. You can do a "where-used" for the include & get the corresponding name of the exit function module.
2. Goto table MODSAP & in the field MEMBER pass the name of the function module & you will get the Exit Name in the NAME.
Hope this helps.

Here is the code for the include program.

MOVE febvw_in TO febvw_out.

Sometimes you will get this error message when checking include code in exits even though there is really no error - it happens because the include does not realise it is in the function due to the navigation index being out of date.
Try activating the code - it may work even though the check said there were errors.
You can also get this issue when trying to drill down on the field in the include to view its structure.

How to add function key to a menu exit in a standard transaction

Hi all,
I have a requirement to add a function key for a menu item in a standard transaction.
In Menu bar we have an option Extras->Other->Repricing . Now my requirement is if i click a function key (ex. F9) the code under the menu exit (Repricing) should trigger. For that i had a function exit EXIT_SAPLJHPA_011 and in this the menu exit SAPLJHPA +CU7 is defined.could anyone suggest me the procedure in detail to add a function key..
Thanks in advance,
Uday.

Hi
for this u have to edit standard PF-status, that particular transaction is using. becarefull as the same pf-status may be used for many programs.
get the PF-status for that program. you can get the pf-status via se80, give the program name and u can get the the list of all the objects of that prigram, there you can edit the standard status and can add the function key to your menu item.

How to find Implemented Function Exits and SMOD Enhancements?

Hi,
I have a list of approximately 100 function exits (EXIT_......) and enhancements in SMOD.
Is there any table or Function Module which can give me the implemented function exits and enhancements from the list that I have.
Thanks in advance.
Mick

steps:
1. SE11
2. Table name: TADIR
3. In the selection screen give object type as CMOD and Object Name as Z*
4.Execute. you will get all exits implemented in your system.
OR
Check the table MODACT and field NAME . Look for the NAME starts with Z or Y ( Z* or Y*) . You will get all enhancement of customer (CMOD)

How to Create Menu Exit

Hi,
Please tell me steps for how to create Menu Exit. Please Help me

MENU EXITS
Menu exits allow you to add your own functionallity to menus. Menu exits are implemented by SAP, and are reserved menu entries in the GUI interface. The developer can add his/her own text and logic for the menu.
Function codes for menu exits all start with "+"
Example
We want to create a new menu item in the Office menu. The text for the menu should be "Run ZTEST", and the menu will
run report ZTEST.
Goto transaction SE43 Area Menu Maintenance
In Area Menu Paramenter type 'S000' (S triple Zero)
Select Change and ignore all the warning screens
Expand the office menu. In the buttom of the office tree you will find a menu named "Customer function"
Double click on the text. In the pop-up screen change the text to "Run ZTEST". Note that the trsnaction code is +C01
Goto transaction SE93 and create transaction +C01 that calls report ZTEST.
Now you will se the menu displayed in the office tree. If you delete transaction +C01 again, the new menu will dissapear.
There are 'only' 177 Menu exits in standard - I couldn't see the right one, too.
But you could search the implemented exits, this should be only a small number. Go to transaction CMOD, enter * and F4, information system (F5), show all selections (Shift+F7) and then you can restrict to search only menu exits.
Of course there is the possibility, that these are added in a different way...
... at least you can be sure, if it's a normal menu exit.

You can achieve this functionality by configuring in IMG.
Please find the info regarding User-Exit's in the following links:

http://www.sap-img.com/abap/a-short-tutorial-on-user-exits.htm
Re: doubt on user exits
user exits and Badis
User exits is the enhancements provided by SAP
You can use them in transactions. Each transaction will have user exits.
If you want to use your own requirements by making your coding while the transaction is run you can use user exits.
For example if you want to run the MRP in MD02 specific to MRP controller you can user exit.
Please also refer the document below.
USEREXIT
Userxits allow us to add our own functionality to SAP standard program
without modifying it . These are implemented in the form of subroutines and hence are also known as FORM EXITs. The userexits are generally collected in includes and attached to the standard program by the SAP.
All Userexits start with the word USEREXIT_...
FORM USEREXIT_..
z..
ENDFORM.
The problem lies in finding the correct userexit and how to find it if one exists for the purpose. Once the correct userexit is found the necessary customer code is inserted in the customer include starting with the z.. in the form routine.
e.g. USEREXIT_SAVE_DOCUMENT_PREPARE
Certain application like SD still provide this form of enhancement using userexit but this practice is no longer being followed for newer extensions instead they are using EXITs which come bundeled in enhancement packages . Neverthiless existing USEREXITS will be supported by SAP an all the newer versions of SAP.
HOW TO FIND USEREXITS
Userexits can be found in number of ways:
1) To find userexits in SD module , goto object navigator(SE80) and select
development class from the list and enter VMOD in it. All of the userexits in SD are contained in the development class VMOD. Press enter and you will find all the includes which contain userexits in SD for different functions like PRICING, ORDER PROCESSING etc. Select the userexit according to the requirement and read the comment inserted in it and start coding .
Some examples of userexits in SD(SALES & DISTRIBUTION ) are:
1)ADDING OF NEW FIELDS IN PRICING
In Pricing in SD the fields on the basis of which pricing is done are derived from the FIELD CATALOG which is a structure KOMG .This structure is used to transfer transaction data to the pricing procedure in SD and is also known as communication structure.This structure KOMG consists of two tables KOMK for Header related fields and KOMP for item related fields. The fields which are not in either of the two tables KOMK and KOMP cannot be used in pricing .Sometimes a need arises when the pricing is to be based on some other criteria which is not present in the form of fields in either of the two tables. This problem can be solved by using USEREXITS which are provided for pricing in SD. Pricing takes place both when the SALES ORDER ( Transaction VA01) is created as well as when INVOICING ( Transaction VF01) is done.Hence SAP provides 2 userexits ,one for sales order processing which is
USEREXIT_PRICING_PREPARE_TKOMP or
USEREXIT_PRICING_PREPARE_TKOMK
Depending upon which table (KOMK or KOMP) the new fields were inserted we use either of the above two userexits.These userexits are found in include MV45AFZZ of the standard SAP sales order creation program SAPMV45A.
In the case of userexit which will be called when invoicing is done ,these
are provided in the include RY60AFZZ which is in the standard SAP program SAPMV45A. The name of the userexits are same. i.e
USEREXIT_PRICING_PREPARE_TKOMP or
USEREXIT_PRICING_PREPARE_TKOMK
These userexits are used for passing the data from the communication structure to the pricing procedure, for this we have to fill the newely created field in the communication structure KOMG for this we fill the code in the above userexit using the MOVE statement after the data that has to be passed is taken from the database table by using the SELECT statement. The actual structure which is visible in these userexits and which is to be filled for that particular field is TKOMP or TKOMK.
Before the coding for these userexits is done ,it is necessary to create a new field in either of the two tables KOMK or KOMP .For this purpose includes are provided in each of them .
To create the field in header data(KOMK) the include provided is KOMKAZ
and to create the field in item data(KOMP) the include provided is KOMPAZ.
One possible example for the need of creating new fields can be e.g. Frieght to be based upon transportation zone ,for this no field is available in field catalog and hence it can be created in KOMK and then above userexits can be used to fill the transportation data to it.
2)The other method of finding userexit is to find the word USEREXIT in the
associated program of the transaction for which we want to determine userexit using SE38.
3)The other method of finding userexits is to find the include in case of SD/MM applications where the userexits are located ,this can be found in the SAP reference IMG generally in the subfolder under SYSTEM MODIFICATION.
Some other examples of userexits in SD are:
USEREXIT_NUMBER_RANGE
This userexit is used to assign a different internal document number to the
sales order(VA01) when it is created depending on some criteria like a different SALES ORGANIZAION(VKORG) .
USEREXIT_SAVE_DOCUMENT_PREPARE
This userexit is used to insert the ABAP code which will be called when
the document (sales order VA01) is just about to be saved.This userexit is used generally for custom checks on different fields , to display some information before the order will be saved or for making changes to certain fields before the sales order will be saved.
Exits & Enhancements
There are mainly six types of EXITs in sap which have been collected in the form of enhancement packages and attached to standard code in SAP.
These are different from USEREXIT in the way that they are implemented
in the form of FUNCTIONs while in USEREXITS we use form routines for their implementation. These are also sometimes known as function exits .
These start from the word EXIT_ followed by the program name and then followed by a three digit number.
e.g. EXIT_SAPMV45A_002
This exit is found in SD in enhancement V45A0002.
TYPES OF EXITS
1)MENU EXITS
2)FUNCTION EXITS
3)TABLE EXITS
4)SCREEN EXITS
5)KEYWORD EXITS
6)FIELD EXITS
We use SAP transactions CMOD and SMOD to manage exits. Before implementing an exit , it is required to create the project by using CMOD
selecting the enhancement e.g. V45A0002 and selecting the component
(one which fulfills our need) i.e the exit which will be implemented in SMOD and after coding has been done the project has to be activated.
An exit can be coded only once.
FUNCTION EXITS
These are used to add functionality through ABAP code . These start from the word EXIT_programname_NNN ending in a 3 digit number. No access code is required to implement any tupe of exit including function exits.
The function exits are called from the standard SAP program in the form
of ABAP statement
CALL CUSTOMER-FUNCTION 'NNN'
This is in contrast to USEREXITs where PERFORM statement is used to call
the required userexit.
To implement the FUNCTION EXITs first of all the project is created and a suitable enhancement package is selected and from its compnents the function exit to be implemented is selected and on double clicking it the exit code will appear in ABAP EDITOR(se38) where a Z include will be found and the customer code should be entered in this include.
e.g.
ADDING A DEFAULT SOLD-TO-PARTY in Sales Order Creation
To show a default sold-to-party in this field when the user creates a sales order (VA01) we can use a function exit .This function exit is located in enhancement no V45A0002 . Before we can choose the exit we have to create a project in CMOD after that enter V45A0002 in the enhancement field and click on the components . In the components you will see the exit EXIT_SAPMV45A_002 . This exit is used for our purpose.
Double clicking on this exit will takes us to function builder (SE37) . This
function exit has one exporting parameters and two importing parameters, we are interested in exporting parameter which is E_KUNNR of type KNA1-KUNNR i.e if we move the desired customer name to this structure(E_KUNNR) it will be shown in the field as the default value when we create the sales order. This function also contains a customer include ZXVVA04 . This include will be used to write our custom code .
Double clicking on this include and it will prompt us that this include does not exists do you want to create this object ,select yes and the include will be created .In this include we can write our own code that will fill the field E_KUNNR.
e.g. E_KUNNR = 301.
Activate the include and Activate the project. Now when ever the SALES ORDER will be created , sold-to-party field will come up with a predefined customer .
FIELD EXITS
The field exits are managed,created,activated through program RSMODPRF. The field exit is associated with a data element existing in ABAP dictionary and hence to the screen field using that data element.
The format of field exit is :
FIELD_EXIT_dataelement_A-Z or 0-9
If a particular screen and program name is not specified than the field exit will effect all the screens containing that data element.
The function module associated with field exit shows two parameters
INPUT and OUTPUT. Input parameter contains the data passed to the field exit when the field exit was invoked by the R/3 , We can write our own code to change the output parameter depending upon our requirements.
Before the field exit can have any effect the system profile parameter
ABAP/FIELDEXIT in all the application servers should be set to YES
ABAP/FIELDEXIT = YES.
