Debugging module pool program

hi guys,
how to debug module pool program.
I have written one user exit in this module pool program, i want to check the value.i don't know the screen number and program name where it is going to effect'?
actually i am validating in this userexit...
anybody knows this....
thanks in advance,
Yad

Hi Yad,
There is a very convenient way of debugging anything in SAP.In the SAP easy access screen choose the icon which denotes the 'Generated a Shortcut on the Desktop'.In the resulting window that appears choose the part where the 'Application' Details are present.Change the TYPE to SYSTEM COMMAND and enter the COMMAND as /H and give some title for e.g 'MYDEBUGGER'.Click on O.K and a shortcut will be placed on your desktop with the title that you have given.Anyplace and anywhere on the SAP screen if you wish to debug just drag the shortcut from ur desktop on to the screen.This is very helpful and would help u to understand the debugging process.
As far as your present scenario is considered put a breakpoint in the user-exit.If your user-exit is getting triggered then the breakpoint will automatically put you into the debugging screen.There is always a way to debug anything.Hope this helps.
Cheers

How to use module pool program in my custom report?

Hi,
I am developing a custom report in abap. I want to fetch data from a standard module pool program.I want output of this standard module pool program to be used in my standad report.Submit cannot be used with module pool programs. How can i do this?Can u please suggest?

HI friend,
For this you can directly use the table fields i.e. each and every module pool screen fields will be having the table name along with its fields (which you can see by double clicking the field and selecting technical settings button) and since it is a standard module pool program that will get populated directly. So you can get the screen field values directly from the table. I think this will help. Please try and let us know wheather it is solved.
Thanks and regards,

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.

Debugging a Module Pool Program(Object Oriented ABAP)

Hello Experts,
Could you please advise me on an efficient debugging technoque of Module Pool Program which is based on Object Oriented ABAP?

Hi
Debugging Module pool program using ABAP objects is same as debugging any other report/module pool program.
Click on the Create shortcut icon on the toolbar.
In the popup window choose "System command" and in the command enter "/h"
A shortcut on the desktop would be created
Drag and drop the shortcut to the modal window to set debugging on.
Approach 2:
Create a txt file on the desktop with the following lines:
[FUNCTION]
Command=/H
Title=Debugger
Type=SystemCommandDrag and drop this file to the modal window to set debugging on.
How do I switch between the Classic and New Debugger
From within the ABAP workbench, select the Utilities->Settings Menu
Select the ABAP Editor Tab
Select the Debugging tab within the ABAP Editor Tab
Select the Classic Debugger or New Debugger radio button

Call Module pool program in report

Dear guys,
i have Module pool program ZSDMODPOOL,which is transaction ZSDORD(ADDON SCREEN),Which creates sales order and shipment.
Now i want, one new screen to display before this ZSDORD Screen. In new screen i will have Table control having Internal table displaying in it.
Now, My requirement is how to pass this New screen internal table datas into Module pool program.
or i can put question as how to call module pool program
from other report program or screen.
Pls give me ideas.
ambichan

You can call the transaction using CALL TRANSACTION, or you can setup a DIALOG and call it using CALL DIALOG. Using CALL DIALOG you will be able to pass values. You create a DIALOG via transation SE35.

Call module pool program from report

Hi,
Iam calling module pool program from a report, while passing values to module pool program, one of the field doesn't have parameter id, how to pass value to it. and also please let me know how to call module pool program.
Appreciate your help.
Thanks in advance
jog

Hi Jog,
Module pool program can be run in background. Most of the BDC's are written on module pool programs and they run in the background.
Also regarrding copying the standard program, if you require to make the changes for every user then instead of copying the program make modification in standard program as copied program are much harder to maintain during support pack implementation or upgrade that modification to standard program.

How to degub the module pool program

Hi friends,
could anyone tell me "How to degub the module pool program"...!!
Thanks in advance..!!

Hi
Debugging of module pool is same as reports, use /h or put breakpoint
but u shud know what u want to check
there are generally two event used in module pool
PBO
This event is used before displaying the screen,It is used to clear fields table, show table control, tabstrip and most important conditionally modify the scrren .
PAI
is used to validate the fields which are entered on the screen with database values and then fetch records from table.
i mean all values to make available in internal table
now u would be sure which part u want to debug.

How to create Long Text in Module Pool Program

Hi all,
I want to develop a new module pool program and I want to use Long text screen in this program and also want this text will store in table.I never develop such type of module pool before.This long text will like sales order long text.Please let me know the steps how I can develop such type of program and how I save long text huge data in table.
Thanks & Regards

Hai ,
here you have to use custom control, for this
DATA: line(256) TYPE c,
      text_tab LIKE STANDARD TABLE OF line,
      field LIKE line.
1) Create custom control in your screen
2)   CREATE OBJECT: container EXPORTING container_name = 'TEXTEDIT',   "--> (this is custom control name in screen)
                   editor    EXPORTING parent = container.
3) CALL METHOD editor->get_text_as_stream "This method reads data from custom control , inserts into itab 'text_tab'
         IMPORTING
          text = text_tab.                                       "
      READ TABLE text_tab INTO line INDEX 1. read the text into wa 'line'

Hi,
May be just for viewing, try downloading from SE80 transaction from the others option.
Here just try issuing the print, it will generate the spool.
Now using the spool, download to your desktop as required. It will have all the information regarding the attributes, fields, elements everything.
The only issue is, may be you need to take all the screens separately.

I have an Input/Output field for that i need to give f4 help, based on that field the related data should sit in to my table control. The thing is there is no relation between the input/output field and the table control fields.
Is this possible? If so how can i do this.

Hi Jagadeesh,
For F4 Values on Screen:
PROCESS ON VALUE_REQUEST
using module call starting with FIELD i.e FIELD field MODULE module
There are number of function modules that can be used for the purpose, but these
can fullfill the task easily or combination of them.
DYNP_VALUE_READ
F4IF_FIELD_VALUE_REQUEST
F4IF_INT_TABLE_VALUE_REQUEST
POPUP_WITH_TABLE_DISPLAY
DYNP_VALUE_READ
This function module is used to read values in the screen fields. Use of this
FM causes forced transfer of data from screen fields to ABAP fields.
There are 3 exporting parameters
DYNAME = program name = SY-CPROG
DYNUMB = Screen number = SY-DYNNR
TRANSLATE_TO_UPPER = 'X'
and one importing TABLE parameter
DYNPFIELDS = Table of TYPE DYNPREAD
The DYNPFIELDS parameter is used to pass internal table of type DYNPREAD
to this FM and the values read from the screen will be stored in this table.This
table consists of two fields:
FIELDNAME : Used to pass the name of screen field for which the value is to
be read.
FIELDVALUE : Used to read the value of the field in the screen.
e.g.
DATA: SCREEN_VALUES TYPE TABLE OF DYNPREAD ,
SCREEN_VALUE LIKE LINE OF SCREEN_VALUES.
SCREEN_VALUE-FIELDNAME = 'KUNNR' . * Field to be read
APPEND SCREEN_VALUE TO SCREEN_VALUES. * Fill the table
CALL FUNCTION 'DYNP_VALUES_READ'
EXPORTING
DYNAME = SY-CPROG
DYNUMB = SY-DYNNR
TRANSLATE_TO_UPPER = 'X'
TABLES
DYNPFIELDS = SCREEN_VALUES.
READ TABLE SCREEN_VALUES INDEX 1 INTO SCREEN_VALUE.Now the screen value for field KUNNR is in the SCREEN_VALUE-FIELDVALUE and can be used for further processing like using it to fill the internal table to be used as parameter in F4IF_INT_TABLE_VALUE_REQUEST ETC.
F4IF_FIELD_VALUE_REQUEST
This FM is used to display value help or input from ABAP dictionary.We have to pass the name of the structure or table(TABNAME) along with the field name(FIELDNAME) . The selection can be returned to the specified screen field if three
parameters DYNPNR,DYNPPROG,DYNPROFIELD are also specified or to a table if RETRN_TAB is specified.
CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'
EXPORTING
TABNAME = table/structure
FIELDNAME = 'field name'
DYNPPROG = SY-CPROG
DYNPNR = SY-DYNR
DYNPROFIELD = 'screen field'
IMPORTING
RETURN_TAB = table of type DYNPREAD
F4IF_INT_TABLE_VALUE_REQUEST
This FM is used to dsiplay values stored in an internal table as input
help.This FM is used to program our own custom help if no such input help
exists in ABAP dictionary for a particular field. The parameter VALUE_TAB is used to pass the internal table containing input values.The parameter RETFIELD
is used to specify the internal table field whose value will be returned to the screen field or RETURN_TAB.
If DYNPNR,DYNPPROG and DYNPROFIELD are specified than the user selection is passed to the screen field specified in the DYNPROFIELD. If RETURN_TAB is specified the selectionis returned in a table.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
EXPORTING
RETFIELD = field from int table whose value will be returned
DYNPPROG = SY-CPROG
DYNPNR = SY-DYNNR
DYNPROFIELD = 'screen field'
VALUE_ORG = 'S'
TABLES
VALUE_TAB = internal table whose values will be shown.
RETURN_TAB = internal table of type DDSHRETVAL
EXCEPTIONS
parameter_error = 1
no_values_found = 2
others = 3.
POPUP_WITH_TABLE_DISPLAY
This FM is used to display the contents of an internal table in a popup window.The user can select a row and the index of that is returned in the CHOISE
parameter.The VALUETAB is used to pass the internal table.
A suitable title can be set using TITLETEXT parameter. The starting and end position of the popup can be specified by the parameters STARTPOS_COL / ROW and ENDPOS_ROW / COL .
CALL FUNCTION 'POPUP_WITH_TABLE_DISPLAY'
EXPORTING
ENDPOS_COL =
ENDPOS_ROW =
STARTPOS_COL =
STARTPOS_ROW =
TITLETEXT = 'title text'
IMPORTING
CHOISE =
TABLES
VALUETAB =
EXCEPTIONS
BREAK_OFF = 1
OTHERS = 2.
e.g.
DATA: w_choice TYPE SY-TABIX.
DATA: BEGIN OF i_values OCCURS 0 WITH HEADER LINE,
values TYPE I,
END OF i_values.
PARAMETRS : id TYPE I.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR id
i_values-values = '0001'.
APPEND i_values.
i_values-values = '0002'.
APPEND i_values.
i_values-values = '0003'.
APPEND i_values.
i_values-values = '0004'.
APPEND i_values.
CALL FUNCTION 'POPUP_WITH_TABLE_DISPLAY'
EXPORTING
ENDPOS_COL = 40
ENDPOS_ROW = 12
STARTPOS_COL = 20
STARTPOS_ROW = 5
TITLETEXT = 'Select an ID'
IMPORTING
CHOISE = w_choice
TABLES
VALUETAB = i_values
EXCEPTIONS
BREAK_OFF = 1
OTHERS = 2.
CHECK w_choice > 0.
READ TABLE i_values INDEX w_choice....now we can process the selection as it is contained
...in the structure i_values.
Other FM that may be used to provide input help is HELP_START .

Dj

How to give the application server file path in the module pool programming

Hi,
     Could somebody help me how to provide the application server file path in module pool programming once the logo is uploaded to sap system.
For eg I have imported a logo name owens into sap system by using transaction se78; now I need to call the path in the below url,
if container2 is initial.
CREATE OBJECT CONTAINER2
EXPORTING
    CONTAINER_NAME              = 'PICTURE_CONTAINER2'.
CREATE OBJECT PICTURE2
EXPORTING
    PARENT = CONTAINER2.
CALL METHOD PICTURE2->SET_DISPLAY_MODE
EXPORTING
    DISPLAY_MODE = CL_GUI_PICTURE=>display_mode_fit_center
EXCEPTIONS
    ERROR        = 1.
CALL METHOD PICTURE2->LOAD_PICTURE_FROM_URL
EXPORTING
    URL    = " ? "
EXCEPTIONS
    ERROR = 1
    Others = 2.
endif.
Thanks in advance

hi Deepu,
Use FM '/SAPDMC/LSM_F4_FRONTEND_FILE' for fetching the data from the application server path/presentation server path
