Hi ,

The values are not geting transferred from the internal table .

Can you paste your code so that the error can be detected.

Else you can debug your program and see why the values are not getting transferred to the internal table .

you can also refer to the Alvaro's blog on List display.....

/people/alvaro.tejadagalindo/blog/2006/11/27/dynamic-alv-list-display

Hope this helps you .

Thanks and Regards

hii swarnil,

it seems that yoou didn't pass the sy-repid value in the variable V_REPID.just chk it

form DISPLAY_DATA .

V_REPID = SY-REPID.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

I_CALLBACK_PROGRAM = V_REPID

....

rgrds,

Hi,

take the sample code... its tested and is working perfectly fine.... you can use this example in your code solve your issue... it replicates your issue to some extent...

DO 10 TIMES.
  wg_field_form-field1 = sy-index.
  wg_field_form-field2 = 2 * sy-index.
  wg_field_form-field3 = 3 * sy-index.
  APPEND wg_field_form to i_field_form.
ENDDO.

wa_fieldcat1_slis-col_pos = '1'.

Re: problem in ALV_BLOCK_LIST_APPEND

SwarnaliBasu — Mon, 24 Aug 2009 07:39:56 GMT

I HAVE USED THE SAME LOGIC , EXCEPT THE PART DO 10 TIMES. wg_field_form-field1 = sy-index. wg_field_form-field2 = 2 * sy-index. wg_field_form-field3 = 3 * sy-index. APPEND wg_field_form to i_field_form. ENDDO.

but just to see it even if i put it same way in my code its creating in output so many lines but output is not coming.

please help

Re: problem in ALV_BLOCK_LIST_APPEND

Former Member — Mon, 24 Aug 2009 07:44:14 GMT

there were certain lines which I had changed and those lines you had commented actually... just copy and paste the complete code removing the do 10 times......enddo.....

copy and paste the code with the call function part also......

and then see if it works or not... if it does not....

copy the complete code in a new program and then check if it works... if it works then compare both the prog line by line....

Hi, Try to change your code like below.


  CALL FUNCTION 'REUSE_ALV_BLOCK_LIST_APPEND'
    EXPORTING
      is_layout                        = ls_layout1
 
      it_fieldcat                      = lt_fieldcat1_slis
      i_tabname                        = 'I_FIELD_FORM'  "Instead of 'i_field_form'. Capital letters in quotes not small letters
      it_events                        = t_events
*   IT_SORT                          =
*   I_TEXT                           = ' '
    TABLES
      t_outtab                         = i_field_form
   EXCEPTIONS
     program_error                    = 1
     maximum_of_appends_reached       = 2
     OTHERS                           = 3.

I hope that it solves. Thanks Venkat.O

Re: problem in ALV_BLOCK_LIST_APPEND

SwarnaliBasu — Mon, 24 Aug 2009 08:05:44 GMT

see the basic idea of cretaing i_field_form is it should have data, i am seeing data inside it but its not getting populated, i copied your program in a new one and saw its wroking but when i implement it in my program i_field_form contains values but it cannot connect with fieldcatlaog i suppose.

did you paste the code which i had given in my previous ex. if not... just paste this and comment your code of appending fieldcatalog....

wa_fieldcat1_slis-tabname = 'I_FIELD_FORM'.
wa_fieldcat1_slis-seltext_l = 'FIELD1'.

wa_fieldcat1_slis-tabname = 'I_FIELD_FORM'.
wa_fieldcat1_slis-seltext_l = 'FIELD2'.

thats ok, but the 1st row of itab i_field_form should come as a header of ALV, and from the second row the content should follow with correspondence with the 1st row.
