Comparing screen input in program in module pool programming(table control)

Experts,
I am a newbie in ABAP. I am working dialog programming where I am replicating PR creation. I am asking user to enter item number, material number and plant. I am validating material number and plant using chain and endchain. This validation is working fine and it throws error message if user enters invalid input. I am able to see corresponding details (corresponding details like unit of measure, delivery date and short text etc. if values entered are correct.) when user clicks on ADD button. Now I have one problem. If user enters same item number twice it should throw error message. I am not able to figure out how it should be done. I thought to set flag = 'X' after user enters item number.
I am using table control. The validation part for material number(matnr) and plant (werks) work fine. I am getting problem while checking entered item number to check duplication.
User should not enter the same item number again.
In my structure i have defined a variable called checkflag(1) type c. and i am doing it now following way. Right now my checkflag code is commented.
Following is my snippet for the same.
Please let me know your ideas/suggestions and advices.
DATA : counter TYPE i,
         itmno1 TYPE i.
SELECT SINGLE matnr
       FROM mara INTO matno WHERE matnr = it_pr-matnr.
SELECT SINGLE werks
         FROM t001w INTO plant WHERE werks = it_pr-werks.
SELECT SINGLE matnr werks
         FROM marc INTO (matno,plant)
    WHERE matnr = it_pr-matnr AND werks = it_pr-werks.
itmno1 = it_pr-bnfpo.
IF ok_code = 'ADD'.
    IF it_pr-matnr <> matno OR it_pr-werks <> plant AND it_pr-bnfpo = ''.
      MESSAGE 'Not a Valid material number or plant. Please enter valid values.' TYPE 'E'.
    ELSEIF it_pr-matnr = matno AND it_pr-werks = plant AND it_pr-bnfpo <> ''.
      SELECT SINGLE maktx FROM makt INTO stext WHERE matnr = it_pr-matnr.
      SELECT SINGLE meins FROM mara INTO tmeins WHERE matnr = it_pr-matnr.
      SELECT SINGLE lpein FROM eban INTO tlpein WHERE matnr = it_pr-matnr.
*      if it_pr-bnfpo = itmno1.
*        it_pr-checkflag = 'X'.
*      endif.
      READ TABLE it_pr WITH TABLE KEY
      checkflag = it_pr-checkflag
      bnfpo = it_pr-bnfpo
      maktx = it_pr-maktx
      matnr = it_pr-matnr
      eindt = it_pr-eindt
      meins = it_pr-meins
      werks = it_pr-werks
      lpein = it_pr-lpein.
*      if it_pr-checkflag = 'X'.
*          message 'Please enter another item number.' TYPE 'E'.
*          endif.
      IF sy-subrc <> 0.
        it_pr-bnfpo = itmno1.
        it_pr-maktx = stext.
        it_pr-lpein = tlpein.
        it_pr-meins = tmeins.
        APPEND it_pr.
      ENDIF.
      IF sy-subrc = 0.
        MESSAGE 'Please enter another item number.' TYPE 'E'.
      ENDIF.
    ENDIF.
ENDIF.

Indeed thank you very much @medha24 and @gargi sarkar.
If I use current-line, I will have to skip first entry as first entry should be appended. Then only I would be able to compare it with newly entered value. I will have to use loop end loop within the PAI. I have already written this code in the validation PAI itself.
I am not getting how I should use loop endloop effectively so that control will go to the next iteration effectively. Right now with this code, I am getting partial success if I enter item number in bulk (more than one item number as input at same time). later, even though I enter correct values I get error message as it doesn't find next entry in the table. It only appends first records only. Therefore, I am looking to enter first entry without any check and later entries should be compared and appended. I would appreciate your ideas/suggestions.
Thank you.
Best reagrds.

Module Pool Progrmaing Table Control

Hi Experts,
I Have Created a Module pool Program, In that I have add a table Control.
i have write all logic and i have to update to the database also. Now my Requirement is when i am enter the data in the table control in first field after that i press enter it will go to the next field this is my requirement..

matnr maktx meins
i have enter the value of matnr after i press tab button it will go to the next field like that i need in replacing of tab button i press enter it will go to the next field.
Thanks
Sankar

Hi ,
Initialy you have to set the cursor inside the table control required filed using SET cursor statement inside the PBO , each user interaction in PAI you have to capture the line of table control where cursor is currently set using GET CURSOR and again in PBO SET the cursor for your required filed .

Problem in module pool with table control scrolling

hi,
i am using the table control in module pool,in the table control i have radion button for all the rows.
After i got the data into the table control ,if i select radio button and if i press vertical scroll bar button, that radio button is deselecting,how to solve this issue.
Please help me.

Hi
Generally we don't keep radiobuttons in table control for selecting the records
We keep check boxes for selecting the records
Radio button is used to select a single from a group of records and at a time only one is selected, where as checkboxes at a time you can select a single or multiple.
So use checkboxes and code correctly see the doc for Table control
syntax:
CONTROLS .
if you only want to determine the row of the table control. SY´-SUBRC allows you to check if the cursor is placed in a row of a table control.
u need to comment the performs of table control fields and write ur own perform statements. And u have to declare the table control fields as separate internal tables.

Module Pool with Table Control.

Hi,
I have developed two screens .
in the first screen the user enters the data and press the Next Push button then
in the second screen it should display data in the table control.
For that purpose I have written code.
when the user press Next Button then I wrote like this.
case ok_code.
when 'NEXT'.
CALL SCREEN '9001'.
ENDCASE.
AND In the PBO Event of the Screen 9001 I have written a Function Module to Popup the data
in the table control.
But the problem is when the user press the Next Button it is displaying table control without
data. But when the press the Back button and again he press the Next Button then it is displaying.
So, Where is the Problem ?
How can I correct it ?
Bye,
Satya.

Hi
IN PAI
case ok_code.
when 'NEXT'.
select the data into an internal table using the entered fields in the first screen.
so data is there in ITAB.
CALL SCREEN '9001'.
ENDCASE.
in PBO.
between loop..
MOVE the internal table data to the table control fields
endloop.
see the help for TC
syntax:
CONTROLS .

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.

How to get center alignment of Input/Output field in Module Pool

Hi Friends,
I am using Input/Output field in my Module pool program. Dynamically i am submitting the text to Input/Output field. What i want is i want to display the submitted text as center. By default It is displaying left aligned.
Thank U in advance.
Mahender.

Hi,
Use syntax "Centered".
take one variable push into the field
write w_variable1 to w_variable2 centered.
next push the varaible to Destination screen input/output Field .
Make sure the Field the Character Type.
