Former Member — Thu, 30 Jan 2014 06:30:48 GMT

Hi All,

i am working in module pool, now i gets a problem at one point.

When i fills my data in table control in module pool and presses

enter, it disappears. i have searched various threads on scn

but still not able to solve my problem, here is my code

please sujjest me the solution.

PROCESS BEFORE OUTPUT.
MODULE DISPLAY.
MODULE SELECT_RECORDS.
*&SPWIZARD: PBO FLOW LOGIC FOR TABLECONTROL 'TBC_ESC'
   MODULE TBC_ESC_CHANGE_TC_ATTR.
*&SPWIZARD: MODULE TBC_ESC_CHANGE_COL_ATTR.
   LOOP AT   IT_FINAL
        INTO WA_FINAL
        WITH CONTROL TBC_ESC
        CURSOR TBC_ESC-CURRENT_LINE.
     MODULE TBC_ESC_GET_LINES.
*&SPWIZARD:   MODULE TBC_ESC_CHANGE_FIELD_ATTR
   ENDLOOP.

MODULE STATUS_9000.

PROCESS AFTER INPUT.

CHAIN.
MODULE EXIT.

Hello Shweta.

Why have you commented this? This module updates the table control data into internal table which will ultimately displayed back via table control.


*      MODULE TBC_ESC_MODIFY ON CHAIN-REQUEST.

Best way for solving this kind of problem is Put a break point in your PAI and debug, check where your internal table is getting cleared..

Hi Arun,

i have already put it into chain..endchain

so commented outside it.

Is it wrong ?

sivaganesh_krishnan — Thu, 30 Jan 2014 07:07:45 GMT

Hi shweta,

Best way is to debug the program.. Try to keep break points inside PAI and PBO. In some place you would have cleared the data.

You would arrive at the solutions once you debug thoroughly.

Sivaganesh

hi,

Inside module TBC_ESC_MODIFY add below code,

describe table it_final lines w_lines.

if tbc-current_line > w_lines.
append wa_final to it_final.
else.
modify it_final from wa_final index tbc-current_line.
endif.

Hi,

It seems you are not filling the internal table in PBO. ( Use append statement to fill the itab ; loop at statement in PBO, processes each line displayed- one by one; you need to use append statement to store the displayed line in the internal table ). After filling the itab - ( Loop at itab statement in PAI does validation on individual fields of the records sequentially ).

Also, before appending make sure that entry does not exist in itab. Otherwise it will see duplicate records.

DPM

sivaganesh_krishnan — Thu, 30 Jan 2014 08:04:19 GMT

save and activate your program and then place a break point..

Arun_Prabhu_K — Thu, 30 Jan 2014 08:12:30 GMT

Ok. Didn't see it properly.

* Have you set Input field attribute for that field?

* Have you declared that field name correctly?

* If that data which you are entering is new data to be inserted into internal table,

then you have write code inside the module MODULE TBC_ESC_MODIFY ON CHAIN-REQUEST to APPEND data.

For instance,

MODULE TBC_ESC_MODIFY ON CHAIN-REQUEST.

MODIFY IT_FINAL from WA_FINAL INDEX TBC_ESC-CURRENT_LINE.

if sy-subrc <> 0.

"Write the logic to APPEND DATA to internal table IT_FINAL.

endif.

ENDMODULE.

Regards.

Hi Praveen,

i have written these code as sujjested by you, but getting error that "Statement "DESCRIBE" is not defined. Check your spelling."

MODULE TBC_ESC_MODIFY ON CHAIN-REQUEST.

         DESCRIBE TABLE IT_FINAL LINES W_LINES.
         IF TBC-CURRENT_LINE > W_LINES.
           APPEND WA_FINAL TO IT_FINAL.
           ELSE .
             MODIFY IT_FINAL FROM WA_FINAL INDEX TBC-CURRENT_LINE.
           ENDIF.

     endchain.
     FIELD WA_FINAL-SEL

Hi Shweta,

Please check I think you have not declared w_lines variable.

Hi Shweta,

put module within CHAIN AND ENDCHAIN.

MODULE VALIDATE_DATA_1021 ON CHAIN-INPUT.
MODULE RGPTBLCTRL_MODIFY_1021.

sample code is

PROCESS BEFORE OUTPUT.
   MODULE RGPTBL1021_CHANGE_TC_ATTR.
   LOOP AT   ITRGPDET
        INTO WARGPDET
        WITH CONTROL RGPTBL1021
        CURSOR RGPTBL1021-CURRENT_LINE.
   ENDLOOP.

MODULE STATUS_1021.
PROCESS AFTER INPUT.
   LOOP AT ITRGPDET.
     CHAIN.
       FIELD WARGPDET-ITEMNO.
       FIELD WARGPDET-MATNR.
       FIELD WARGPDET-MAKTX.
       FIELD WARGPDET-MEINS.
       FIELD WARGPDET-QUANTITY.
       FIELD WARGPDET-WERKS.
       FIELD WARGPDET-SELECT.
       MODULE RGPTBLCTRL_MODIFY_1021.
     ENDCHAIN.
   ENDLOOP.
MODULE USER_COMMAND_1021.

code of module RGPTBLCTRL_MODIFY_1021.

MODULE RGPTBLCTRL_MODIFY_1021 INPUT.
   MODIFY ITRGPDET
     FROM WARGPDET
     INDEX RGPTBL1021-CURRENT_LINE.
   IF SY-SUBRC <> 0.
     APPEND ITRGPDET.
   ENDIF.
ENDMODULE.                 " RGPTBLCTRL_MODIFY_1021 INPUT

Hi All,

one problem i am facing also, i have created a USER_COMMAND in PAI,

but in the main program when i am using this code, my debugger didn't

get at perform disp_data on hitting enter, what may be the reason.

This is my code

CASE SY-UCOMM.

     WHEN 'BACK' OR 'CANCEL' OR 'EXIT'.
       LEAVE TO SCREEN 0..
     WHEN 'ENTER'.
       PERFORM DISP_DATA.
     WHEN 'SAVE'.
       PERFORM MATERIAL_SAVE..

   ENDCASE.
CLEAR : SY-UCOMM.

Re: Data disappears on enter in table control

Former Member — Thu, 30 Jan 2014 14:57:14 GMT

Shweta,,

There is no function code as "ENTER, "

Hence the perform is also not executed.

If you need the correct fcode,try to see the sy-ucomm value in debugger

Hi Praveen,

i am declaring w_lines as shown below, but it is giving me error as "

Please tell me how could i solve this

   LOOP AT IT_FINAL.
     CHAIN.
       FIELD WA_FINAL-SNO.
       FIELD WA_FINAL-DESCRIPTION.

         DESCRIBE TABLE IT_FINAL LINES W_LINES.
         IF TBC-CURRENT_LINE > W_LINES.
           APPEND WA_FINAL TO IT_FINAL.
           ELSE .
             MODIFY IT_FINAL FROM WA_FINAL INDEX TBC-CURRENT_LINE.

Hi,

On screen logic flow , you can't use data statement. Double click on a module. Inside the module, put data statement.

Kindly take the help of your colleagues to sort out the issue. Otherwise see the logic in Program 'DEMO_DYNPRO_TABLE_CONTROL_1' & 'DEMO_DYNPRO_TABLE_CONTROL_2' .

Also, on net you will find lot of information on module pool table control.

Hi Shweta Chouhan,

You cannot declare variable like the above.. Please do declare it in top include .

Hi,

i don't have any colleagues to talk, so i am worried about it.

And i have seen many threads, but not able to solve it.
