How to use Field exit

Hi,
Our consultant wants to use field exit as a way to validate a certain field in a screen for tcode MB1B.
I tried to follow the steps below to create a field exit but it seems that I'm missing a step or two because it doesn't work.
1. Run program RSMODPRF in se38.
2. Enter the data element and the number of field exit
3. create and activate the function module
After this I run tcode MB1B but it seems that it did not pass through the field exit.
Do I need an extra step to make the field exit work? And how do I assign a field exit to a certain screen?
Hope to hear from you guys soon.
Thanks!

Hi Jackie,
1.Enter the tcode SE38
2.In the ABAP Editor enter the program name RSMODPRF
3.Execute
4.Then you will get a screen with Data Element and Number of Field Exit
Here enter the Data Element(for example MATNR for material no.) and
enter 0 to 9 or A to Z in the second field(I am taking 0 in my example)
5. Execute
6.Then you will be navigated to the Function Builder screen(se37) with FM name FIELD_EXIT_MATNR_0
The FM name contains the Data Element(MATNR) and No. of Field Exit (0) (in this case)
7.Then click on CREATE.
8.Give the Fun. Grp name and SAVE
9.It will take youn to the Source code wherein ypu have to write the code asb per your requirement
For Example:
FUNCTION FIELD_EXIT_MATNR.
IF INPUT BETWEEN 125 AND 150.
MESSAGE E000(ZMM) WITH "Material not allowed".
ENDIF.
ENDFUNCTION.
10.Then if you try to enter the values in MM01 for Material no.,this effect comes into picture
If you enter Material no between 125 and 150 you will get "Material not allowed".
Follow the above procedure with your requirements(data element,screen name)
And to assign a screen name and program to a Field Exit:
In the 'Field Exits for Data elements' screen, in the application tool bar you can assign the Program name and Screen no. by clicking Assign Prog. /Screen.
You will get the above screen by
1. goto tcode CMOD
2. Enter PRFB in the command prompt and press ENTER
Another procedure for implementing the Field Exit:
One more way to do this is goto tcode CMOD.
Enter PRFB in the command prompt and press ENTER
In the screen select the menu Field exit --> Create and follow the same procedure as above.

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,
Rajeev

Hi,
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.

How to use User Exit for SD...

Hi there,
My client's requirement is to block the overall status of the Sales Order header under status tab to be blocked when user r-enters a new scheduled date in the "First Date" column in the SO.
When they goto VA02, & put a new date it must automatically put a delivery block in the header as well as make the order header status to be blocked.
I see the First date field in the SO is in a Structure RV45A, the field name is ETDAT.
Can you let me know how to use User exit MV45AFZZ?

How to use rri exit IF_EX_SMOD_RSR00004

Hello Forum,
we need to use the rri exit to map source fields depending on their values to the fields of the receiving query.
Unfortunately, we've not found any kind of documentations or examples showing how to use the EXIT_SAPLRSBBS_001 and its parameters I_THX_RECEIVER, I_THX_SENDER, E_THX_MAPPING.
Has anyone an idea how to use this exit properly?
Many thanks in advance for any idea.

How to use field symbols

can anyone tell me how to use field symbols. What effect it has on performance of a program?
what r its avantages?
iam working on a report where iam facing a lot of problems in performance issue. can anyone tell how field symbols are useful in this regard?
thanx to all

FIELD-SYMBOLS
Basic form
FIELD-SYMBOLS <fs>.
Additions
1. ... STRUCTURE s DEFAULT wa
2. ... TYPE t
3. ... TYPE LINE OF t
4. ... LIKE s
5. ... LIKE LINE OF s
Effect
This statement declares a symbolic field called <fs>. At runtime, you can assign a concrete field to the field symbol using ASSIGN . All operations performed with the field symbol then directly affect the field assigned to it.
You can only use one of the additions.
Example
Output aircraft type from the table SFLIGHT using a field symbol:
FIELD-SYMBOLS <PT>.
TABLES SFLIGHT.
ASSIGN SFLIGHT-PLANETYPE TO <PT>.
WRITE <PT>.
Addition 1
... STRUCTURE s DEFAULT wa
Effect
Assigns any (internal) field string or structure to the field symbol from the ABAP/4 Dictionary ( s ). All fields of the structure can be addressed by name: <fs>-fieldname . The structured field symbol points initially to the work area wa specified after DEFAULT .
The work area wa must be at least as long as the structure s . If s contains fields of the type I or F, wa should have the structure s or at least begin in that way, since otherwise alignment problems may occur.
Example
Address components of the flight bookings table SBOOK using a field symbol:
DATA SBOOK_WA LIKE SBOOK.
FIELD-SYMBOLS <SB> STRUCTURE SBOOK
DEFAULT SBOOK_WA.
WRITE: <SB>-BOOKID, <SB>-FLDATE.
Addition 2
... TYPE t
Addition 3
... TYPE LINE OF t
Addition 4
... LIKE s
Addition 5
... LIKE LINE OF s
Effect
You can use additions 2 to 5 to type field symbols in the same way as FORM parameters (see also Type assignment of subroutine parameters). ASSIGN performs the same type checks as with USING parameters of FORM s.

How to use field symbols in program

how to use field symbols can any one explain with example please..
Regards,
venki...

Hi
Field Symbols
Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned to it after it has been declared in the program.
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to each field symbol before you can address the latter in programs.
Field symbols are similar to dereferenced pointers in C (that is, pointers to which the content operator * is applied). However, the only real equivalent of pointers in ABAP, that is, variables that contain a memory address (reference) and that can be used without the contents operator, are reference variables in ABAP Objects.
All operations programmed with field symbols are applied to the field assigned to it. For example, a MOVE statement between two field symbols moves the contents of the field assigned to the first field symbol to the field assigned to the second field symbol. The field symbols themselves point to the same fields after the MOVE statement as they did before.
You can create field symbols either without or with type specifications. If you do not specify a type, the field symbol inherits all of the technical attributes of the field assigned to it. If you do specify a type, the system checks the compatibility of the field symbol and the field you are assigning to it during the ASSIGN statement.
Field symbols provide greater flexibility when you address data objects:
If you want to process sections of fields, you can specify the offset and length of the field dynamically.
You can assign one field symbol to another, which allows you to address parts of fields.
Assignments to field symbols may extend beyond field boundaries. This allows you to address regular sequences of fields in memory efficiently.
You can also force a field symbol to take different technical attributes from those of the field assigned to it.
The flexibility of field symbols provides elegant solutions to certain problems. On the other hand, it does mean that errors can easily occur. Since fields are not assigned to field symbols until runtime, the effectiveness of syntax and security checks is very limited for operations involving field symbols. This can lead to runtime errors or incorrect data assignments.
While runtime errors indicate an obvious problem, incorrect data assignments are dangerous because they can be very difficult to detect. For this reason, you should only use field symbols if you cannot achieve the same result using other ABAP statements.
For example, you may want to process part of a string where the offset and length depend on the contents of the field. You could use field symbols in this case. However, since the MOVE statement also supports variable offset and length specifications, you should use it instead. The MOVE statement (with your own auxiliary variables if required) is much safer than using field symbols, since it cannot address memory beyond the boundary of a field. However, field symbols may improve performance in some cases.

The syntax check performed in an ABAP Objects context is stricter than in other ABAP areas. See Cannot Use Untyped Field Symbols ad Cannot Use Field Symbols as Components of Classes.
Effect
This statement declares a symbolic field called <fs>. At runtime, you can assign a concrete field to the field symbol using ASSIGN. All operations performed with the field symbol then directly affect the field assigned to it.

Addition 3
... TYPE REF TO DATA
Addition 4
... TYPE LINE OF type
Addition 5
... LIKE s
Addition 6

Addition 7
... TYPE tabkind
Effect
You can define the type of the field symbol using additions 2 to 7 (just as you can for FORM parameters (compare Defining the Type of Subroutine Parameters). When you use the ASSIGN statement, the system carries out the same type checks as for USING parameters of FORMs.
This addition is not allowed in an ABAP Objects context. See Cannot Use Obsolete Casting for FIELD SYMBOLS.
In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. See Defining Types Using STRUCTURE.
Effect
Assigns any (internal) field string or structure to the field symbol from the ABAP Dictionary (s). All fields of the structure can be addressed by name: <fs>-fieldname. The structured field symbol points initially to the work area wa specified after DEFAULT.
The work area wa must be at least as long as the structure s. If s contains fields of the type I or F, wa should have the structure s or at least begin in that way, since otherwise alignment problems may occur.
Example
Address components of the flight bookings table SBOOK using a field symbol:
DATA SBOOK_WA LIKE SBOOK.
FIELD-SYMBOLS <SB> STRUCTURE SBOOK
DEFAULT SBOOK_WA.
WRITE: <SB>-BOOKID, <SB>-FLDATE.

How to use Field-symbol with dynamic select query

Can anybody tell me, how to use field-symbols in the dynamic select query.

FIELD-SYMBOLS <fs> { typing | STRUCTURE struc DEFAULT dobj }.
1. ... typing
2. ... STRUCTURE struc DEFAULT dobj
The FIELD-SYMBOLS statement declares a field symbol <fs>. The name conventions apply to the name fs. The angle brackets of the field symbols indicate the difference to data objects and are obligatory. You can declare field symbols in any procedure and in the global declaration section of an ABAP program, but not in the declaration section of a class or an interface. You can use a field symbol in any operand position in which it is visible and which match the typing defined using typing.
After its declaration, a field symbol is initial - that is, it does not reference a memory area. You have to assign a memory area to it (normally using the ASSIGN statement) before you can use it as an operand. Otherwise an exception will be triggered.
eg.
FIELD-SYMBOLS <fs> TYPE ANY.
DATA: BEGIN OF line,
 string1(10) VALUE '0123456789',
 string2(10) VALUE 'abcdefghij',
 END OF line.
WRITE / line-string1+5.
ASSIGN line-string1+5(*) TO <fs>.
WRITE / <fs>.
output:
56789

How to Creating Field EXIT

Hi,
Please tell me the step by step procedure for creating Filed Exit

Hi 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

How to use field "responsible Cost center" in Report Painter

Hi
I create report painter by using standard LIbrary and want to use field "Responsible Cost Center" as a parameter in order to display report in hierachy.But the standard Library "6O1" doesn't provide this field .
So I try to create new library by copy the standard "6O1" and using the structure "CCSS".But it doesn't show this "Responsible Cost Center" Field as a parameter .
Please give me an advice step by step the way to get this field as parameter in report painter
regards
Chompleon

Hi,
I have a similar requirement. I have followed OSS note 358251 as an example to add the 'Responsible Cost Center', however it doesn't display in the report even after I choose the field for display. The steps I have followed are -
1) Added the field ZZ_KOSTV in the include structure CI_CC1S.
2) Using transaction GRCT, table CCSS, I added a characteristic KOSTV with Def field OBJNR, and filler routinue EZZ_FILL_KOSTV. I then wrote code in this routinue to populate the value KOSTV from AUFK table in the include program FK21REZZ. In debug mode, I can see correct values are populated in this field.
3) I created a copy of an existing report in the library 6O1, changed it and in the Total line, added the field Responsible Cost Center to the Selected Characteristics. When I save, regenerate and execute the report, the value for Responsible Cost Center doesn't get displayed though the displayed orders have a value populated in this field and when I debug I can see the value is passed ut correctly form the filler routinue to the field KOSTV.
Please help and let me know what I need to do to be able to see this field in the output result.
