How do I de-activate a field exit?
All,
A field exit has been implemented for the material field at TCODE MM01/02/03 which does not allow me to access to these 3 TCODE. I know field exit can't be debugged. Is there anyway for me to exclude/deactivate this field exit? THanks in advance.
Hello,
First Go tcode in CMOD in the command window enter tcode =PRFB , this would give list of all the Field Exit development in the system, click on any of the checkboxes go to menu FieldExit in that select Deactivate
regards

How to link or call two FIELD EXIT
Hi Friends,
I've to do a Field exit object for MIGO...and my logic is i've to capture the meory id concept by Export and Import function.So, I heard that I've to create one field exit with Export function and again create under one more field exit to import the memory id from Export.
I know the logic of Export and Import.But i dont know how to fix it in the function module,means how to create one field exit and call the same under one more field exit.
Pls do the needful and post me with some good field exit examples for my reference.i.,e How to give codes inbetween Function and End Function. and how to call this field exit with one more field exit for import stmt.
if u find BADI or USER EXIT is good for MIGO,pls reply with good and correct example functions.
Thanks and regards
sankar.
Edited by: sankar babu on Dec 29, 2007 10:00 AMHello Sankar,
Just you want to use the functionaly Import and Export , that why you required two Fields Exit in transitation MIGO.
I suggest MIGO is huge transitation which conver some table like MSEG and BSEG which affect the performance of the program. Better you go with one field Exit . Although there are many Some are attach Below.

How to use the method for field-exit to trigger the workflow?
Dear all,
I want the workflow to trigger , when ever the check box for DELIVERY COMPLETED is checked in ME22N .
I have developed a method in SE18 for the corresponding field and defined function module SWE_EVENT_CREATE with BOR bus2012 and event CHANGED.
Now how to use this method to make my workflow to trigger?Shall I create an event in delegated bus2012 and can I call this method?
Thanks and regards,
S.SureshHi
You want to place your method which is defined for particular filed.right?
For that you can go for BADI. First you check whether any badi is getting called form that tcode ME22N. Then to place your method, implement that BADI. So whenever that BADI is getting called, it will call your event. Through Event workflow will be getting triggered.

Hi,
Please tell me the step by step procedure for creating Filed ExitHi Mohan,
This will be too useful for u...
Step by step procedure for creating Field Exits
There are eight steps to creating a field exit:
Step 1: Determine Data Element
Step 2: Go To Field Exit Transaction
Step 3: Create Field Exit
Step 4: Create Function Module
Step 5: Code Function Module
Step 6: Activate Function Module
Step 7: Assign Program/Screen
Step 8: Activate Field Exit
Step 1: Determine Data Element
- Before you can begin adding the functionality for a field exit, you must know the corresponding data element.
- An easy way to determine the data element associated to a particular screen field is to:
Go the appropriate screen.
Position the cursor in the appropriate field.
Press F1 for field-level help.
Click on the Technical info pushbutton (or press F9) on the help dialog box.
On this Technical Information dialog box, the data element will be specified if the field is 'painted' from the ABAP/4 Dictionary.
Step 2: Go To Field Exit Transaction
- The transaction to create field exits is CMOD.
- You can use the menu path Tools -> ABAP/4 Workbench -> Utilities -> Enhancements -> Project management.
- From the initial screen of transaction CMOD, choose the Text enhancements -> Field exits menu path.
- After choosing this menu path, you will be taken to the field exits screen. From here, you can create a field exit.
NOTE : Even though you use transaction CMOD to maintain field exits, you do not need to create a project to activate field exits.
Step 3: Create Field Exit
- From the field exit screen of transaction CMOD, choose the Field exit -> Create menu path.
- After choosing this menu path, a dialog box will prompt you for the appropriate data element .
- Enter the data element name and click the Continue pushbutton.
- Now, you will be able to create the function module associated to the data elements field exit.
Step 4: Create Function Module
- You will automatically be taken to the Function Library (SE37) after entering a data element name and clicking the Continue pushbutton.
- In the Function module field, a function module name will be defaulted by the system based on the data element specified. This name will have the following convention:
FIELD_EXIT_<data element>
- You can add an identifier (an underscore followed by a single character ).
- The first function module for a data elements field exit must be created without an identifier.
- To create the function module, click on the Create pushbutton, choose menu path Function module -> Create, or press F5.
- After choosing to create the function module, you will get the warning: "Function module name is reserved for SAP". This message is just a warning so a developer does not accidentally create a function module in the field exit name range. By pressing Enter, you will be able to go ahead and create the function module.
- Before coding the function module, you will have to specify the function modules attributes -- function group, application, and short text.
Step 5: Code Function Module
- From the function modules attributes screen, click on the Source code pushbutton or choose the Goto -> Function module menu path to the code of the function module.
- Here you will add your desired functionality for the field exit.
- Remember that field exits function module will have two parameters -- one importing parameter called "INPUT" and one exporting parameter called "OUTPUT". These parameters will be set up automatically by the system.
- You must remember to assign a value to the OUTPUT field. Even if the value does not change, it must be moved from the INPUT field to the OUTPUT field.
Step 6: Activate Function Module
- After coding the function module, you must remember to activate it.
- Use the Function module -> Activate menu path to activate the function module.
- At this point, you can return to the field exit transaction.
- You should be able to 'green arrow' back to this transaction.
- When you return to the field exit transaction, you will see an entry for the newly created field exit.
- At this point, the field exit is global. That is, it applies to all screens that use a particular data element. On any screen that uses the data element, the corresponding field exit function module will be triggered, once it is active.
- Also, the field exit will not be triggered yet because it is inactive.
Step 7: Assign Program/Screen
- This step is only needed if you want to make a field exit local.
- To make a field exit local, select the field exit and click on the Assign prog./screen pushbutton.
- In the dialog box , indicate the appropriate program name and screen number.
This information indicates that the field exit is local to the specified screen in the specified program.
- In the dialog box, you determine which function module gets executed for the field exit by specifying the identifier in the Fld. Exit field.
- If this field is left blank, the function module triggered will be 'FIELD_EXIT_<data element>'.
- If a single-character identifier is entered into the field, the function module triggered will be 'FIELD_EXIT_<data element>_<identifier>'.
Step 8: Activate Field Exit
- The field exit must be active for it to be triggered by the system.
- Activate the field exit by choosing the Field exit -> Activate menu path.
- After assigning the field exit to a change request, its status will change to Active and it will be triggered automatically on the appropriate screen(s).
NOTE : In order to activate the field exit the profile parameter abap/fieldexit = YES must be set on all application servers
Set the above config in Tcode RZ11 -
Need a document for field exit....urgent
Can any one please send a document for field exit or have a simple document on how to work on a field exit with screen shots. pls send it ...its urgent
Thanks and regards
Nandha kumar RHi,
A field exit is a type of user exit.
A user exit is a hook where you can inject your own add-on functionality or behavior to SAPs standard business applications without having to modify the original applications.
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.
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.
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.
Field exits (SMOD/CMOD) Questions and Answers
1. Field exit was created with CMOD, but is not processed when calling the screen.
- Since the field exit is not processed until PAI, an action must be triggered on the screen (Return, Save, ...).
- Set profile parameter abap/fieldexit to YES and restart the system.
- After activating the function module FIELD_EXIT... and the field exit, leave the transaction on whose screen the field exit is to be executed. The screen is not generated until the transaction is started.
- Do not work on different application servers since there may be some delay before the field exit is activated.
- The profile parameter must be set on all or none of the application servers.
- If the field exit is to only be active on specific screens, check whether you chose the correct program and the correct screen
number (take care with subscreens).
- Using SE51 -> Field list, check that the screen field does have a reference to a data element. In the name of the field exit use the name of the data element and not the field name.
- After transport, field exits are marked as active but will not be processed.
Tip: First try deactivating the field exit once more and then afterwards, activate it again.
2. How is performance affected by setting abap/fieldexit?
- If a screen is generated and the profile parameter is set, a check is run on 2 tables (TDDIR, TDDIRS) to see whether a field exit must be generated for the respective field. In practice, the screen load is not generated until the screen is selected after an
update. The user should not notice any difference because screen generation is very fast.
3. Can you read the contents of other screen fields in the field exit?
- In principle, every field exit can store its value in the global variables of the function group (TOP) and hence make them
available to other field exits. Note here that field exits are always called and not only if an entry is made in the field or if the field is empty. In addition, it is not possible to make any assumptions about the order in which the field exits will be called in the future.
4. How does the field exit behave on step loop fields ?
- After the user has entered data, the field exit is called in PAI as often as there are visible fields in the step loop. The system
variable SY-STEPL is incremented each time. If a new value is assigned to the field, it is displayed in the module between LOOP and ENDLOOP. This module is also called once for each visible step loop line.
5. Can field exits be debugged ?
- No. Field exits must be tested separately in the ABAP/4 Development Workbench. For errors which only occur in the screen environment, it is helpful to write interesting variable to the file system using TRANSFER... . These can then be analysed there.
6. What can you do if the field contents are no longer transported to to ABAP/4.
- Check whether a value is assigned to the field OUTPUT.
7. When is the field exit called if a conversion exit is attached to the
data element ?
- The field exit is called after the conversion exit. This means that the INPUT field receives the data in the same format as the
ABAP/4 program also receives it.
8. Although a global field exit is inactive, a function module is called which does not exist (for example FIELD_EXIT_PROGRAMM_@)
- This is an error in the kernel which no longer occurs as of 3.0C. As a temporary measure, it is useful to assign a program and a screen which do not exist to the field exit and then activate the field exit.
9. Field exit is not visible in CMOD, although created.
- If you want to create a field exit for a data element, a function module is proposed with the name FIELD_EXIT_. This
function module must exist for the field exit to work. If you do not create this function module, but do create one with a suffix,
the data element is not displayed in CMOD.
10. Field exit is not executed although it is active.
- Fields which do not have the 'Input field' attribute usually do not trigger a field exit. The field exit is designed to allow an
extended input check. It is therefore only called for input fields - even if they are not ready for input at runtime of the application by LOOP AT SCREEN.
This rule does not apply, however, if the field is located within a steploop. Here the field will be always activated, even if it is
invisible.
- Field exits can only be executed for fields that are directly related tothe dictionary. If the relation is indirect, i.e. via an ABAP declaration ( LIKE ), no field exit can be executed.
11. Field exits on check buttons do not work
- Field exits are only intended for input fields. As check buttons count as graphical elements, you cannot install field exits on
them.
12. Field exits do not work on selection screens
SAP Field Exits
From 4.6c onwards, Field exits will no more be supported by SAP. They removed the function of field exit but they had given lot of flexibility through userexit.
However, if you still required it, here is how to activate it :-
First called up transaction CMOD.
Then called up transaction PRFB.
or
Activation of the field exits and assignment of the dynpros can also be carried out using program RSMODPRF. For this purpose, the program must be started without parameters (input fields remain blank). If required, new field exits can be created using program RSMODPRF (see the program documentation).

Hello Abapers,
I need ur help to find out the field exit available for VA11 screen.
How to find the field exit wht is the procedure?
ThksHi Venkateswar,
First you check this link once.,
http://www.****************/Tutorials/ExitsBADIs/MK01/FieldExit.htm
Field exits are frozen on the 4.6C maintenance level and are not further developed. This means that the existing functionality is kept with all restrictions (see also the last item below). Existing exits can be further used and are called at runtime as usual.
Existing exits can be maintained using program RSMODPRF (run the program using transaction SE38). Activation of the field exits and assignment of the dynpros can also be carried out using program RSMODPRF. For this purpose, the program must be started without parameters (input fields remain blank).
If required, new field exits can be created using program
RSMODPRF (see the program documentation).
Please find below the step by step procedure for field exit :-
There are eight steps to creating a field exit:
Step 1: Determine Data Element
Step 2: Go To Field Exit Transaction
Step 3: Create Field Exit
Step 4: Create Function Module
Step 5: Code Function Module
Step 6: Activate Function Module
Step 7: Assign Program/Screen
Step 8: Activate Field Exit
Step 1: Determine Data Element
Before you can begin adding the functionality for a field exit, you must know the corresponding data element.
An easy way to determine the data element associated to a particular screen field is to:
Go the appropriate screen.
Position the cursor in the appropriate field.
Press F1 for field-level help.
Click on the Technical info pushbutton (or press F9) on the help dialog box.
On this Technical Information dialog box, the data element will be specified if the field is 'painted' from the ABAP/4 Dictionary.
Step 2: Go To Field Exit Transaction
The transaction to create field exits is CMOD.
You can use the menu path Tools -> ABAP/4 Workbench -> Utilities -> Enhancements -> Project management.
From the initial screen of transaction CMOD, choose the Text enhancements -> Field exits menu path.
After choosing this menu path, you will be taken to the field exits screen. From here, you can create a field exit.
NOTE : Even though you use transaction CMOD to maintain field exits, you do not need to create a project to activate field exits.
Step 3: Create Field Exit
From the field exit screen of transaction CMOD, choose the Field exit -> Create menu path.
After choosing this menu path, a dialog box will prompt you for the appropriate data element .
Enter the data element name and click the Continue pushbutton.
Now, you will be able to create the function module associated to the data elements field exit.
Step 4: Create Function Module
You will automatically be taken to the Function Library (SE37) after entering a data element name and clicking the Continue pushbutton.
In the Function module field, a function module name will be defaulted by the system based on the data element specified. This name will have the following convention:
FIELD_EXIT_<data element>
You can add an identifier (an underscore followed by a single character ).
The first function module for a data elements field exit must be created without an identifier.
To create the function module, click on the Create pushbutton, choose menu path Function module -> Create, or press F5.
After choosing to create the function module, you will get the warning: "Function module name is reserved for SAP". This message is just a warning so a developer does not accidentally create a function module in the field exit name range. By pressing Enter, you will be able to go ahead and create the function module.
Before coding the function module, you will have to specify the function modules attributes -- function group, application, and short text.
Step 5: Code Function Module
From the function modules attributes screen, click on the Source code pushbutton or choose the Goto -> Function module menu path to the code of the function module.
Here you will add your desired functionality for the field exit.
Remember that field exits function module will have two parameters -- one importing parameter called "INPUT" and one exporting parameter called "OUTPUT". These parameters will be set up automatically by the system.
You must remember to assign a value to the OUTPUT field. Even if the value does not change, it must be moved from the INPUT field to the OUTPUT field.
Step 6: Activate Function Module
After coding the function module, you must remember to activate it.
Use the Function module -> Activate menu path to activate the function module.
At this point, you can return to the field exit transaction.
You should be able to 'green arrow' back to this transaction.
When you return to the field exit transaction, you will see an entry for the newly created field exit.
At this point, the field exit is global. That is, it applies to all screens that use a particular data element. On any screen that uses the data element, the corresponding field exit function module will be triggered, once it is active.
Also, the field exit will not be triggered yet because it is inactive.
Step 7: Assign Program/Screen
This step is only needed if you want to make a field exit local.
To make a field exit local, select the field exit and click on the Assign prog./screen pushbutton.
In the dialog box , indicate the appropriate program name and screen number.
This information indicates that the field exit is local to the specified screen in the specified program.
In the dialog box, you determine which function module gets executed for the field exit by specifying the identifier in the Fld. Exit field.
If this field is left blank, the function module triggered will be 'FIELD_EXIT_<data element>'.
If a single-character identifier is entered into the field, the function module triggered will be 'FIELD_EXIT_<data element>_<identifier>'.
Step 8: Activate Field Exit
The field exit must be active for it to be triggered by the system.
Activate the field exit by choosing the Field exit -> Activate menu path.
After assigning the field exit to a change request, its status will change to Active and it will be triggered automatically on the appropriate screen(s).
NOTE : In order to activate the field exit the profile parameter abap/fieldexit = YES must be set on all application servers

Now a simple question of Field exit.
well, im really very glad because my last post was a success and i can solve de problem!!!!thank you all...
this time i need in the VF01 on one field ('Reference'/Xblnr), when the user press save, to show some popup allowing entry data, so the user may choose some keys from a Ztable that i have to create, and then continue saving.
May i use a field exit for this?what steps shall i follow to activate a field exit and put my code?
Note: there isn't an User exit that appear in the moment i need, the one i asked in my last post doesn't work for this and any of the others finded in ZFindexit. when i'm debugging <b>'perform userexit_pricing_prepare_tkomk' </b>
appeared, is this an User exit? inside this perform i have changed manually while debugging the field i need and the proccess ended OK. how can i activate this exit?
well, i'm sure that someone know the asnwer....
i'll be very glad with the ones who can help me!!!!
and i'll give points in rewards for those who help me as a gratefulness of my part...
i'm waiting your help, thank in advance....Hi andrew,
you will have a standard program RSMODPRF for field exits.
Execute that program and create a a field exit(function module) for 'XBLNR' giving the data element of XBLNR and number of the field exit as inputs.
There you can write the related code...
Hope this helps you.

Reason and Prerequisites
Note
Field exits are frozen on the 4.6C maintenance level and are not further developed. This means that the existing functionality is kept with all restrictions (see also the last item below). Existing exits can be further used and are called at runtime as usual.
Existing exits can be maintained using program RSMODPRF (run the
program using transaction SE38). Activation of the field exits and
assignment of the dynpros can also be carried out using program
RSMODPRF. For this purpose, the program must be started without
parameters (input fields remain blank).
If required, new field exits can be created using program
RSMODPRF (see the program documentation).
Solution
1. Field exit was created with CMOD, but is not processed when calling the screen.
Since the field exit is not processed until PAI, an action must be triggered on the screen (Return, Save, ...).
Set profile parameter abap/fieldexit to YES and restart the system.
After activating the function module FIELD_EXIT... and the field exit, leave the transaction on whose screen the field exit is to be executed. The screen is not generated until the transaction is started.
Do not work on different application servers since there may be some delay before the field exit is activated.
The profile parameter must be set on all or none of the application servers.
If the field exit is to only be active on specific screens, check whether you chose the correct program and the correct screen number (take care with subscreens).
Generate the screen on which the exit should be active using SE51. It is possible that it was not correctly generated. If you want to be sure that all screens that use the data element are regenerated, you can transfer Report rsmodfdg from the correction instructions and start it with SE38. The Report uses the affected data element as the input parameter and regenerates all screens that use the data element.
Using SE51 -> Field list, check that the screen field does have a reference to a data element. In the name of the field exit, use the name of the data element and not the field name.
After transport, field exits are marked as active but will not be processed. Tip: First try deactivating the field exit once more and then activate it again.
2. How is performance affected by setting abap/fieldexit?
If a screen is generated and the profile parameter is set, a check is run on 2 tables (TDDIR, TDDIRS) to see whether a field exit must be generated for the respective field. In practice, the screen load is not generated until the screen is selected after an update. The user should not notice any difference because screen generation is very fast.
3. Can you read the contents of other screen fields in the field exit?
In principle, every field exit can store its value in the global variables of the function group (TOP) and hence make them available to other field exits. Note here that field exits are always called, not only if an entry is made in the field or if the field is empty. In addition, it is not possible to make any assumptions about the order in which the field exits will be called in the future.
4. How does the field exit behave on step loop fields ?
After the user has entered data, the field exit is called in PAI as often as there are visible fields in the step loop. The system variable SY-STEPL is incremented each time. If a new value is assigned to the field, it is displayed in the module between LOOP and ENDLOOP. This module is also called once for each visible step loop line.
5. Can field exits be debugged ?
No. Field exits must be tested separately in the ABAP/4 Development Workbench. For errors which only occur in the screen environment, it is helpful to write interesting variables to the file system using TRANSFER... . These can then be analysed there.
6. What can you do if the field contents are no longer transported to ABAP/4?
Check whether a value is assigned to the field OUTPUT.
7. When is the field exit called if a conversion exit is attached to the data element?
The field exit is called after the conversion exit. This means that the INPUT field receives the data in the same format as the ABAP/4 program receives it.
8. Although a global field exit is inactive, a function module is called which does not exist (for example FIELD_EXIT_PROGRAMM_@). This can lead to an ABAP dump error when function module FIELD_EXIT_<data element name> is called.
This is an error in the kernel which no longer occurs as of Release 3.0C. As a temporary measure, it is useful to assign a program and a screen which do not exist to the field exit and then activate the field exit.
Due to performance reasons, the active/inactive indicator is stored in the screenload. This can cause inconsistencies between Source and Load. Generate the affected screen with se51. If you want to be sure that all screens that use the data element are regenerated, you can transfer Report rsmodfdg from the correction instructions and start it with se38. The Report uses the affected data element as the input parameter and regenerates all screens that use the data element.
9. Field exit is not visible in CMOD, although created.
If you want to create a field exit for a data element, a function module is proposed with the name FIELD_EXIT_<data_element>. This function module must exist for the field exit to work. If you do not create this function module, but do create one with a suffix, the data element is not displayed in CMOD.
10. Field exit is not executed although it is active.
Fields which do not have the 'Input field' attribute usually do not trigger a field exit. The field exit is designed to allow an extended input check. It is therefore only called for input fields - even if they are not ready for input at runtime of the application by LOOP AT SCREEN.
This rule does not apply, however, if the field is located within a steploop. Here the field will be always activated, even if it is invisible.
Field exits can only be executed for fields that are directly related to the dictionary. If the relation is indirect, i.e. via an ABAP declaration (<fieldname> LIKE <dictionary element>), no field exit can be executed.
11. Field exits do not work on selection screens.
Results from the previous item since ABAP-internal fields and never the original Dictionary fields are used on selection screens.
12. Field exists do not work on check buttons.
Field exits are only intended for input fields. As check buttons count as graphical elements, you cannot install field exits on them.
13. How can all screens that use a data element be generated?
If you want to be sure that all screens that use a specific data element are regenerated, you can transfer Report rsmodfdg from the correction instructions into a customer report (e.g. zsmodfdg). The Report regenerates all screens. In this way, you can ensure that active field exits refer to screens and that inactive exits cannot be called on any screen. The Report uses the affected data element as the input parameter. The affected data element is in the name of the exit: FIELD_EXIT_<data element name>.
14. Restriction of usage
Field exit technology was developed for input fields on dynpros and cannot be used for other/new dynpro elements. This means that this technology does not offer support for the new ScreenPainter elements such as graphical elements (e.g. checkbuttons, radiobuttons, dropdown listboxes), controls (except for table controls which are supported like a step loop), or selection screens.

Hi Gurus,
i have a problem, in MM01(Basic data1) there is field called Prod.hierarchy(dataelement is prodh_d), for this data element how to create Field Exits and how to assign to MM01 Tcode.
the code part i have to write is
1. To validate MARA-PRDHA field length (field exit can handle this). the field length should be 18 char.
2.Copy the value of MARA-PRDHA to MVKE-PRODH (the code of the field exit above, you can do field-symbol technique to transfer value from mara-prhda to mvke-prodh).
plz. do the needfull information with all the steps ASAP.
Thanks & Regards,
Sudheer.You can create a field exit to the data element by running the report RSMODPRF.
You will then have to assign the the program name & screen No. (In this case the program name & screen No. in MM01 transaction.)
You will have to write a field exit for MARA-PRDHA and within that ensure that the field length is 18char.( The input value you read should be of 18 char).
You can read the screen field value by using the fn. module to read the screen values & put that value inside MVKE-PRODH. This can be written in another exit.
Important Things to Note.
1.You cannot debug a field exit.
2. Assign the correct program name & screen no. to activate the field exit.
3. This is written at data element level.
Hope this helps...
Let me know if you need any further details.

Deepu.

The profile parameter abap/fieldexit is set to YES during screen generation. A screen load is generated that allows you to branch to field exits.
This parameter may only be set in the customer system.
Note: If the parameter has been set, you must check that, for each field, the system branches to the correct corresponding function module during screen generation. For performance reasons, you should not set this parameter during generation unless field exits have actually been created for your system.
Procedure
Set the abap/fieldexit parameter to YES in the system profile and restart your SAP system.
How to solve this problem....

Field Exits for Data Elements
Description
Maintenance transaction for creating and activating field exits
As part of the extension concept, SAP allows you to install a field exit for each screen field. Similar to the conversion exit, the system branches at the field exit at DCI (DATA COMMUNICATIONS INPUT) to a function module, if the field is an input field and a function code was triggered. The function module must adhere to the following naming convention:
Prefix: FIELD_EXIT_
Infix: <Data element name>
Suffix: _0 to _9 (optional), _A to _Z
The interface is automatically generated during the creation of the function module, and has 2 parameters:
Import parameter: INPUT
Export parameter: OUTPUT
After a function code has been triggered the contents of the field are made available to the FB via the "INPUT" import parameter. You can edit this and, when changed, make it available to the ABAP/4 processor in "OUTPUT". The input field contents are usually passed on: you can simply write OUTPUT = INPUT.
If, e.g., you have activated the field exit for the data element 'PROGRAM', then the fields of all the screens, which refer to the data element 'PROGRAM', branch to the function module FIELD_EXIT_PROGRAM. This includes the field 'Program' of the initial screen SAPMS38M0100 in transaction SE38, for example.
If you do not want the function module to be accessed from all screens, assign particular screens to the data element PROGRAM. By allocating an exit number, it is also possible to branch to other function modules with the corresponding suffix _0 ... _Z.
Example: You have assigned screen SAPMS38M0100 and exit number 5 to data element 'PROGRAM'. The corresponding field on SAPMS38M0100 branches to FIELD_EXIT_PROGRAMM_5.
As soon as you activate an exit, the corresponding screens are invalidated.
Note: Field exits are only taken into account during screen generation if the parameter abap/fieldexit = 'YES' is set in the system profile.
Requirements
Set the profile parameter abap/fieldexit = 'YES' before system start.
Limitations
The following ABAP statements are not allowed in the function modules of field exits:
BREAK-POINT,
CALL SCREEN, CALL DIALOG, CALL TRANSACTION, SUBMIT,
COMMIT WORK, ROLLBACK WORK,
COMMUNICATION RECEIVE,
EXIT FROM STEP-LOOP,
MESSAGE I, MESSAGE W.
Note:
Field exits cannot be edited with the debugger.
You should not use any external Performs in field exits. The ABAP processor shares the table work areas of externally called programs with those of the first caller. This could lead to errors at field exits that can hardly be analyzed, as field exits are sometimes slipped into the flow of the program at unforeseen events.
Questions and answers on field exits
1. A field exit was created with the CMOD and activated, but it does not get executed when the screen is called.
Since the field exit is not executed until DCI, some action must occur in the screen (e.g. press Return, saving....).
Set the abap/fieldexit profile parameter to YES and start the system again.
After the FIELD_EXIT... function module has been activated and the field exit has been activated, the transaction in whose screen the field exit is to be executed must be terminated. The screen is not generated until it is called.
Do not work on different application servers, otherwise there may be a delay before the field exit becomes active.
The profile parameter must be set either on all application servers or on none.
If the field exit is to be active in certain screens only, then you should check whether you have selected the correct program and the correct screen number (Careful with SUBSCREENS Do not rely on the F1 information for the field!
2. How does setting abap/fieldexit affect the performance?
If a screen is generated and the profile parameter is set, then the system checks in 2 tables (TDDIR, TDDIRS) to see whether a field exit has to be generated for the field. In practice the screen load after a Put is not generated until the screen is called. The user will not experience a noticeable delay, since screen generation is extremely fast.
3. Can the contents of other screen fields be read in a field exit?
In principle all fields can be copied to global variables in the TOP or the function group. However, since the order in which the field exits are called is not guaranteed, this possibility should not be used.
4. How does the field exit work in step-loop fields?
After data input to DCI the field exit will be called as many times as fields are visible on the step-loop. The SY-STEPL system variable is incremented each time. If a new value is assigned to be field, then it will be visible in the module between LOOP. ENDLOOP. This module will also be called as many times as there are visible step-loop lines.
5. Can field exits be debugged?
No. Field exits have to be tested in isolation in the development environment. To analyze problems that occur only in the screen environment, the relevant variables can be written to the file system using TRANSFER... and can be analyzed there.
6. What should one do if the field contents are not getting transported to ABAP/4?
Check whether you have assigned a value to the OUTPUT field.
7. When does the field exit get called in the case that there is a conversion exit attached to the data element?
The field exit will be called after the conversion exit. This means that the INPUT field contains the data in the same form as that in which the ABAP/4 program also gets them.

What is Field Exit--Step By Step procedure..
Hi,
What is Field Exit.
And How to validate a field on any screen using field exit.
what is the Procedure.
Please give me Step by Step Procedure.
Points will be given for straight answers..
Regards,
KiranPlease find below the step by step procedure for field exit :-
There are eight steps to creating a field exit:
Step 1: Determine Data Element
Step 2: Go To Field Exit Transaction
Step 3: Create Field Exit
Step 4: Create Function Module
Step 5: Code Function Module
Step 6: Activate Function Module
Step 7: Assign Program/Screen
Step 8: Activate Field Exit
Step 1: Determine Data Element
Before you can begin adding the functionality for a field exit, you must know the corresponding data element.
An easy way to determine the data element associated to a particular screen field is to:
Go the appropriate screen.
Position the cursor in the appropriate field.
Press F1 for field-level help.
Click on the Technical info pushbutton (or press F9) on the help dialog box.
On this Technical Information dialog box, the data element will be specified if the field is 'painted' from the ABAP/4 Dictionary.
Step 2: Go To Field Exit Transaction
The transaction to create field exits is CMOD.
You can use the menu path Tools -> ABAP/4 Workbench -> Utilities -> Enhancements -> Project management.
From the initial screen of transaction CMOD, choose the Text enhancements -> Field exits menu path.
After choosing this menu path, you will be taken to the field exits screen. From here, you can create a field exit.
NOTE : Even though you use transaction CMOD to maintain field exits, you do not need to create a project to activate field exits.
Step 3: Create Field Exit
From the field exit screen of transaction CMOD, choose the Field exit -> Create menu path.
After choosing this menu path, a dialog box will prompt you for the appropriate data element .
Enter the data element name and click the Continue pushbutton.
Now, you will be able to create the function module associated to the data elements field exit.
Step 4: Create Function Module
You will automatically be taken to the Function Library (SE37) after entering a data element name and clicking the Continue pushbutton.
In the Function module field, a function module name will be defaulted by the system based on the data element specified. This name will have the following convention:
FIELD_EXIT_<data element>
You can add an identifier (an underscore followed by a single character ).
The first function module for a data elements field exit must be created without an identifier.
To create the function module, click on the Create pushbutton, choose menu path Function module -> Create, or press F5.
After choosing to create the function module, you will get the warning: "Function module name is reserved for SAP". This message is just a warning so a developer does not accidentally create a function module in the field exit name range. By pressing Enter, you will be able to go ahead and create the function module.
Before coding the function module, you will have to specify the function modules attributes -- function group, application, and short text.
Step 5: Code Function Module
From the function modules attributes screen, click on the Source code pushbutton or choose the Goto -> Function module menu path to the code of the function module.
Here you will add your desired functionality for the field exit.
Remember that field exits function module will have two parameters -- one importing parameter called "INPUT" and one exporting parameter called "OUTPUT". These parameters will be set up automatically by the system.
You must remember to assign a value to the OUTPUT field. Even if the value does not change, it must be moved from the INPUT field to the OUTPUT field.
Step 6: Activate Function Module
After coding the function module, you must remember to activate it.
Use the Function module -> Activate menu path to activate the function module.
At this point, you can return to the field exit transaction.
You should be able to 'green arrow' back to this transaction.
When you return to the field exit transaction, you will see an entry for the newly created field exit.
At this point, the field exit is global. That is, it applies to all screens that use a particular data element. On any screen that uses the data element, the corresponding field exit function module will be triggered, once it is active.
Also, the field exit will not be triggered yet because it is inactive.
Step 7: Assign Program/Screen
This step is only needed if you want to make a field exit local.
To make a field exit local, select the field exit and click on the Assign prog./screen pushbutton.
In the dialog box , indicate the appropriate program name and screen number.
This information indicates that the field exit is local to the specified screen in the specified program.
In the dialog box, you determine which function module gets executed for the field exit by specifying the identifier in the Fld. Exit field.
If this field is left blank, the function module triggered will be 'FIELD_EXIT_<data element>'.
If a single-character identifier is entered into the field, the function module triggered will be 'FIELD_EXIT_<data element>_<identifier>'.
Step 8: Activate Field Exit
The field exit must be active for it to be triggered by the system.
Activate the field exit by choosing the Field exit -> Activate menu path.
After assigning the field exit to a change request, its status will change to Active and it will be triggered automatically on the appropriate screen(s).
NOTE : In order to activate the field exit the profile parameter abap/fieldexit = YES must be set on all application servers

PR creation for 'F" in ME51N, ME52n, the cost center field exit getactivate
Dear Gurus,
We have a Cost center Field exit activation, meaning when a PR is generated, the system will validate only for his department cost center. Its working fine
The issue, when we create PR through ME51n or me52n for Acct Assign "F" here we are going to enter only Work order number and GL number, not cost center. Still this field exit has activation, here the same error message popup, which suppose not to be.
So in MM configuration, i have disabled Cost center field for acct assignment "F".
Now when i create a PR for F, for single account assignment, the system will alllow, but if i want to distribute the qty to different work order, the system goes for validation for cost center field exit.
How to resolve for multiple assignment, how to deactivate the Cost center field exit for this case, its woking fine of Single account assignment (after disable the cost center field for Account Assignment "F")
Please help me out or any way to do this?
Regards
RS
Edited by: RS on Sep 14, 2009 7:40 AMHi,
Cross check you have Cost Center field is Hidden for Account Assignment Category A (Asset) in t.code:OME9. Now change Cost Center field as Display for Account Assignment Category A and save.
Now create a new PO with Account Assignment Category A and find the difference how Cost Center appearing in your PO in “Account Assignment” TAB.

hi friends,
i am new to field exit.i want to write field exit for ebeln.
when user tries to change po number error message should get display.
what logic i have to write in function module.
can any any one help me plz .
sonuin se38 execute report RSMOPRF ...
there you give element name of EBELN field...
and execute..
you'l get field exit created for EBELN...
in this field exit do your coding....

Using Field Exit for a field in table KNA1
Hi everyone,
I am working on a ticket, the problem is we have a field called STRAS in table KNA1 which holds the address of the customer but now we want to increase the length of this field from 35 charachters to 55 due to some business requirement. SO my question is if this can be done using Field Exit and if yes.. can you please tell me how as I have never used Field exits.
Thanks,
RajeevHi,
Using field exit, you can only validate the data entry for the field (either globally or on a particular screen field)
This is usually done by implementing the field exit for the data element corresponding to the field(in your case STRAS_GP)
Hence you cannot increase the length of the field using the concept of the field exits...
Please note that after SAP R/3 4.6c, SAP has stopped the creation of field exits and there will be no support for any new ones created.

Documentation about Screen, Menu and Field Exits
Hi all!!
I need some documentation about Screen, Menu and Field Exits.
I´m very interested specially on steps by steps.
My mail is [email protected]
Helpful posts will be rewarded.
Thanks in advance and regards,
Manuel.<b>Types of Exits </b>
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.
<b>Menu Exits</b>
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.
<b>Screen Exits</b>
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.
<b>Function Module Exits </b>
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.
In 4.6c, you can use "RSMODPRF" program to create field exits.
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.
reward points if it is usefull..
