Module pool program - populating values for columns in Table control

Hi all,
In my module pool program Table control i am having 10 columns fields.
in one of the column field i have used 'PROCESS ON VALUE-REQUEST' to get the material no.
in that F4 search help list is having releated information of the material like material group, company code, description etc.
user while searching for material they will use F4 search help and in that list they will select the material .
From the list I need releated information of the materials like material group, company code, description etc
to be populated in other columns while selecting the material .( User is not ready to enter all the values for the fileds)
I appended the releated values for the material in the Table control Internal table in the Process on value-request Module.
(after selecting material by the user from F4 search help)
even then I am not getting the data in the screen.
kindly help me how to proceed to get the data in other columns.
Thanks in advance,
sharma

Hi Himanshu Verma ,
Thanks for fast reply.
but i tried with field names available in F4 Internal table.
even then I am not getting.

ELSE .
    V_TAB-matnr = RETURN_VALUES-FIELDVAL.
endif.
I have used the above code. I am not getting the field values available in ITAB_DYNPFLD_MAPPING.
kindly help me how to get the exact row for the F4 table.
Thanks in advance.

Not setting selected value in column of table control

Hi,
I have MATNR field in table control.
In PAI code is as follow.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
MODULE VALIDATE.
LOOP WITH CONTROL TC_FORMV.
FIELD /SISLEMCU/CNVADTL-MATNR SELECT *

When i take the help in MATNR column the above query works fine but when i select the entry from help MATNR is not gets set in column in table control.
Plz help me regarding this.
Thankx in adv.

Deepak.

When you select a value, PBO as well as PAI gets triggered. When PAI gets triggered, your query gets executed which gives sy-subrc <> 0 and due to this it might not filling the data selected..

How to write module pool program

hai,
what is the module -pool program ?
what are the procedures to write the module-pool program.
plz give the simple program for module-pool programs?
regards
surender

Hi
This component though is not attached to the screen painter, plays important role in transaction. Normally, for reports, on line executable programs are written but for transaction, Module Pool Programs are written. The module pool program contains only modules to handle various events associated with screen and data declaration statements.
System divides the module pool program into several include program. These are global field, PBO modules, and PAI modules. It is entirely users decision whether to use these modules or write directly into main program.
Creation of Module Pool Program
You can create module pool program either through
Object browser
System automatically creates the module pool program and for these program which are created through object browser, system creates the include modules.
Or
ABAP/4 editor
It is similar to normal program creation. Type of program should be given M and is not created by system.
Communication between Dynpro and Module Program
For each screen, the system executes the flow logic, which contains corresponding events. The control is passed to Module Pool Program. Module Pool Program handles the code for these events and again passes back control to the flow logic and finally to screen. Unlike on line program, in this case, the control remains with flow logic. The switching of control between flow logic and module pool program and back is common process when user executes transaction.
Creation of a Complete Transaction
Steps involved to create a complete transaction
     Create module pool program.
     From screen painter create screens.
     Write flow logic for each screen.
     Write code for all the events in module pool program.
     Check for any error in screen and flow logic.
     Generate each and every component of screen i.e. flow logic and screen.
     Single screen can be tested using Screen Painter.
     Create transaction code through object browser.
     Generate the transaction code.
     User can execute the transaction by entering the transaction code in the command field.
Handling Function Code
The function code or OKCODE is the last field of Field list. Function code can be handled as follows:
During the Designing of the screen, a function code is assigned to pushbutton.
     In field list, developer needs to specify OKCODE as last field.
     In module program it is a global field and can be evaluated in the PAI event.
     A function code is treated in the same way, regardless it comes from pushbutton, menu item or any other GUI element.
When the user clicks on the Display button, you want to display details of sflight, with corresponding carrid and connid (which is entered by the user).
Module pool program to handle this particular screen is as follows:
Program YVTEST7.
TABLES: SFLIGHT.
DATA: OKCODE (4).
MODULE INPUT1 INPUT,
CASE OKCODE.
   WHEN DISP.
     SELECT * FROM SFLIGHT
            WHERE CARRID = SFLIGHT CARRID AND
                           CONNID = SFLIGHT CONNID.
     ENDSELECT.
     LEAVE TO SCREEN 200.
   WHEN EXIT. LEAVE TO SCREEN 0.
ENDCASE.
ENDMODULE.               INPUT1 INPUT
MODULE USER_COMMAND_0200 INPUT.
CASE OKCODE.
WHEN BACK. LEAVE TO SCREEN 100.
ENDCASE.
ENDMODULE.                    USER_COMMAND_0200 INPUT
When the user clicks on display, control is transferred to screen no. 200 on which you display sflight details & on the same screen, when user clicks on BACK button, he comes back to main screen.
Flow logic for screen 100 is as follows:
PROCESS AFTER INPUT.
MODULE INPUT.
Flow logic for screen 200
PROCESS AFTER INPUT.
USER_COMMAND_0200.
MODULES: Modules are handled in module pool program.
You need to write flow logic for screen 200 and design screen 200.
In case of transaction transfer of data from program to screen is automatic i.e. you need not transfer the data from program to screen explicitly. The fields, which you define in the screen receives the data from program and displays the same.
The Field Checks
As already mentioned Transaction is the only method, which SAP recommends to update the database tables. Data entered in the database table should be valid and correct. Data entered is validated at each and every point. ABAP/4 offers various methods to validate data and those are as follows:
     Automatic field checks
     Checks performed in the flow logic
     Checks performed in the ABAP/4 module pool program
Automatic Field Checks
These checks are based on the field information stored in the dictionary. These checks are performed by the system automatically when the user enters the data for the screen field. System performs these checks before PAI event is triggered. Types of field checks performed by system are as follows:
     Required input
While designing the screen, for particular screen field if you click the Req. Entry checkbox, the field becomes mandatory. When the transaction is executed if user leaves this particular field blank, the system displays error message. User cannot proceed until the user enters some data.
     Proper Data Format
Each field has its own data format whether it is table field or screen field. Whenever data is entered, system checks for the proper format of the data. For example date. Each user has its own format for date, which is defined in the user master record. If the date defined in the user master record is in the format DD/MM/YYYY, if the user enters the date, say, in YY/DD/MM, the user displays the error message. System also checks for the value of month or days. For example if month entered is greater than twelve then the error message is displayed.
     Valid Value for the Field
In data dictionary two tables are related by Primary key-Foreign key relationship. Whenever the user enters the data, the system checks for the check table values.   Also in Domain, if you have fixed values, then the system checks for these values.
Automatic field checks are repeated each time the user enters the data.
About at Exit Command
Automatic field checks can be avoided by AT EXIT-COMMAND, which works exactly the same way as Cancel works on application tools bar. In the R/3 screen, if you want to quit the processing of that particular screen without entering the mandatory fields, user can click the Cancel button. Same functionality can be incorporated in the user-defined transaction by using AT EXIT-COMMAND. This module can be called before the system executes the automatic field checks and it goes without saying that before PAI event. Code for AT EXIT-COMMAND in flow logic and in module pool program can be written as follows:
In Flow Logic
Process After Input.
Module exit AT EXIT-COMMAND.
         In module pool program.
Module exit.
Case okcode.
When Exit.
Leave to screen 0.
To achieve this kind of functionality a pushbutton or menu item should be assigned a function type E. It tells the system to process this particular module before carrying out any field checks.
Flow Logic Validations
Consider the case where you want user to enter only LH and SQ for sflight-carrid. In this case, you are restricting value of a screen field. This cannot be achieved by automatic field check. Hence there is a need of additional validation. It can be done in flow logic by using following statement:
Field -
Values
Syntax
PAI.
Field sflight-carrid values (LH).
For multiple values
PAI.
Field sflight-carrid values (LH SQ).
Field sflight-price values (between 1000 and 2000).
In this case when the user enters the value, PAI is triggered and field is checked for that particular value. If the value entered happens to be wrong, that field is enabled for user to enter. If you have multiple Field statements in your flow logic, it is sequential execution.
Consider the following case:
PAI.
Module assign.
Field sflight-carrid values (LH SQ).
In ABAP/4
Module assign.
Data: carrid1 like sflight-carrid.
Carrid1 = sflight-carrid.
Endmodule.
In this case, Sflight-carrid is used in the flow logic before the field statement. The system will give invalid value or some previous value as the field sflight-carrid is used in module before it is checked i.e., field statement is after the module in which sflight-carrid is being used. The field is not available to the system unless it executes the field statement. Field statement transfers the values to the program and is done only once. If you dont have Field statement in your flow logic, transfer of values takes place in PAI event.
Consider one more case where you have multiple field statement
PAI.
Field Sflight-carrid values (LH).
Field Sflight-connid values (0400 0500).
In this case if the user enters only carrid wrong, then this particular field is enabled and rest of the fields are disabled for user to input. Many times if the user enters wrong value for one field, then you might want to give option to user to enter all the fields, which is not possible by using Field statement only. This functionality can be achieved by CHAIN ENDCHAIN.
Syntax
Chain.
Field sflight-carrid value (LH).
     Field sflight-connid values (between 200 and 500).
Endchain.
Field sflight-price values (100 1000).
In this case, if the user enters wrong value only for carrid, both the fields i.e. carrid and connid are enabled as they are grouped together in the Chain statement. The field price will be disabled for input. Usually, logically related fields are grouped together with Chain-Endchain statement.
Module Pool Program Validations
Checking fields ABAP/4 program includes
     Field statement in flow logic.
     Module statement in ABAP/4 module pool Program.
Syntax
PAI.
Field sflight-carrid module <name>.
This module can be handled in the main program i.e. module pool program.
In ABAP/4 program
Module Check.
Select single * from sflight where carrid = sflight-carrid.
If sy-subrc ne 0.
     Message e001.
Endif.
In this case, field sflight-carrid is checked in the table for its existence.
Dynamically Calling the Screens
About Displaying Next Screen
Transaction is a sequence of screens, which are displayed one after the other. The next screen displayed depends upon the attributes of first screen. In attributes you need to give Next Screen number i.e. if next screen displayed should be 200 screen, then this number should be given in next Screen attributes. These are static attributes of the screen. By default, if nothing is specified in the program, the system branches out to the screen number, which is specified in the attribute screen.
In this case, if user selects MARA pushbutton, then fields from Mara table are displayed. When the user clicks on the MARD, then the fields from MARD table are displayed. Depending upon users selection, the screen is branched out and this has to be done during runtime. This functionality can be achieved by dynamically calling the screen in module pool program.
The screen can branch out to new screen depending upon user selection. Following command in module pool program can do this:
     SET SCREEM
     CALL SCREEN
     LEAVE TO SCREEN <NUMBER>
All these commands override the specifications given in the attributes. This overriding is temporary. The values stored in the attribute are not changed.
Set Screen
Syntax
Set screen <number>.
In module pool program
Case okcode.
     When DISP.
          Set screen 200.
     When LIST.
          Set screen 300.
Endcase.
In this case, the entire processing of current screen takes place and then the system branches out to next screen. If you want to branch out to the next screen without processing the current screen, LEAVE SCREEN should be used along with the SET SCREEN.
For Example:
Case okcode..
     When DISP.
          Set screen 200.
          Leave Screen.
     When LIST.
          Set screen 300.
          Leave Screen.
Endcase.
When SET SCREEN is used, control cannot be transferred to the main screen or previous screen, unless you write code for the same.
Call Screen
Usually used for pop up screens. Many times, there is a need for user to enter additional information or secondary information on another screen or pop up screen. Once the user enters the data, he should be able to go back to main screen or to the screen where he started. This is not possible by using SET SCREEN. CALL SCREEN achieves this functionality.
Syntax
Call Screen 200.
Will simply call a screen number 200 from a main screen. Once the screen is displayed the user can enter all the data and return to the main screen by clicking BACK button.
To call screen as pop up screen the syntax is
Call screen starting at <col.no.> <line no>
                     Ending at <col no> <line no>.
In this case window will be popped as window and user can close it by using BACK button.
Leave to screen
To SET a new screen without processing current screen, you need to use the following two statements together:
SET SCREEN 200.
LEAVE SCREEN.
Or a Single statement
LEAVE TO SCREEN 200.

Disable columns in table control based on condition

Hello Gurus,
     I am having a table control in my module pool program.Out of 25 columns , I am having 12 columns on months wise like (jan, feb, march....).Now my concern is based on current month I want to enable the column of month rest all months will be in disable mode.So that the user can enter his/her time of work.Could you please tell me any way.I tired to read tc-cols and stored in col with index but its not working I wrote this code for first month without any condition
READ TABLE tC-COLS INTO col INDEX 22.
   col-SCREEN-INPUT = 0.
   MODIFY tC-COLS FROM col INDEX 22.
but its not working.I wrote this code in PBO as well as i tried in PAI as wellstill my columns is in enable mode.Also when user clicks on button then only the table control required fields should start working like months enable/disable process.for eg. I am having 2 button one is Create and other is Search on both these buttons after click the condition for enable/disable months should work.
Thanks
Gaurav

Hi,
In my scenario, I have used months as radio buttons. A month is selected and "enable" button must be clicked so that only the corresponding column of the month turns into an editable mode.
I have attached the output.
The field can be disabled or enabled by using the line type of <table_control_name>-cols.
It contains the screen elements. For disabling / enabling, use active element in screen.
This must be written in PBO event of the corresponding screen containing the table control.

Reg : Variant saving for Module Pool Programming

Hey Friends,
Plz help me in how to create variant for Module Pool Programming as in normal reports.Thanx in advance.

Hi,
You can create variants for Module pool program using the transaction SHD0. You can create Screen variants for your screens using this Tcode.
Go to SHD0 -> Give the Transaction code(ZTRAN) for which you want to create a variant -> name of some variant (ZVAR) -> create -> takes you to your transaction -> Give the values that you want to be displayed as variants -> Click on Save -> Opens a pop up to confirm the screen entries -> Check the check boxes of those fields that you have entered the data with (the column with check boxes that says W.Content) -> Exit and Save -> Save the variant -> You can see a screen variant created (ZVAR_0100)
Now Goto -> Create variant transaction -> Give your transaction variant name (ZVAR) -> Select Transaction with variant -> Takes you to SE93 transaction -> Give the transaction variant name -> save. Run with the created transaction.

How to validate the field values in module pool program?

Hi Guys
     I am working with module pool programming.
     Here I want to validate the fields like below.
     with out filling all the fields if I click SAVE option it has to show a message that all fields has to be filled. This can be done by checking all the fields individually.
     I think it can be done through <b>LOOP AT SCREEN ......ENDLOOP</b>. sequence.
     If it is possible, can anyone help me?

You need to write the Module in between the CHAIN and ENDCHAIN statment in SE51
If you send a warning or error message from a module <mod> that you called using a FIELD statement as follows:
CHAIN.
FIELD: <f1>, <f 2>,...
MODULE <mod1>.
FIELD: <g1>, <g 2>,...
MODULE <mod2>.
ENDCHAIN.
all of the fields on the screen that belong to the processing chain (all of the fields listed in the field statements) are made ready for input again. Other fields are not ready for input. Whenever the MODULE statement appears within a processing chain, even if there is only one FIELD attached to it, all of the fields in the chain (not only the affected field) are made ready for input again, allowing the user to enter new values. If the fields in the processing chain are only checked once, the PAI processing continues directly after the FIELD statement, and the preceding modules are not called again.
Look at the DEMO program DEMO_DYNPRO_FIELD_CHAIN.

Online Background job for Module pool program

Hi,
I need to process the dialog program in background. Normally for any executable report programs by default we will have that functionality. But i need the same functionality for my module pool program. User needs 2 execute buttons - one is for direct excute (foreground execute) and the other one is for back ground processing.
I tried with the 3 function modules job_open, job_submit & job_close. But i am keep on getting some issues and i am not sure how those will work because i wrote all the validations in direct exucte user command, now if user clicks on Background how that logic will be called and how it will be processed.
Can any one give your valuable suggestions.
regards
Jaya

How to access screen field value in a module pool programming?

Hi Experts,
   I have create a module pool program SAPMYDLG. It contains two screens 100 and 200.
   The first screen contains Employee_ID field. This field is not a dictionary field.
   In the second screen 200, I want to access the value of Employee_ID field from first screen.
   For this I created a global variable v_empid in TOP include.
   Then in the PAI of the screen 100 I have assigned the screen field value to global variable.
   v_empid = Employee_ID.
   But this gives an error saying " Field Employee_ID not defined".
   What am I doing wrong? How can I access the screen field value?
Thanks
Gopal

Hi,
Employee_ID field also must u define in the top include when u define that 100 screen and 200 screen will access.

Entering values in MARA table using module pool programming

Hi All,
I need a help from you all. I want to enter the values in the MARA table using module pool programming.
Can you please give me the detailed approach and if possible then code also as i am new to ABAP.
Thanks in Advance

Create the screen fields with ref to field in MARA table, once data is entered on screen by user then fill appropriate structure of FM BAPI_MATERIAL_SAVEDATA. If call to Fm BAPI_MATERIAL_SAVEDATA is successful then call FM BAPI_TRANSACTION_COMMIT to make changes permanent in database .

BADI's being used in MP000100 (module pool program for Infotype 1)

Hi,
In module pool program MP000100( for Infotype 1 i.e. HR related), what are the BADI's being used in PBO module of screen no- 2000 ?
I need to add some codes, if there is no BADI then where i can add codes as i need to default organizational field according to position ID field ?
Thanking you in anticipation.

Why do you need a BAdI for that? Your Business/Functional Analyst should be able to handle it using a feature via the Tcode PE03.
BTW, HRPAD00INFTY is one that can be useful.
