Problem in getting selected row in table control

former_member1292715 — Wed, 13 Jan 2010 12:58:51 GMT

Hi guys,

I am really frustrated of getting the row, selected in table control. I can see hudreds of post in the same topic in SDN. But I can't figure out where I went wrong.

I have table control, in that I set the attribute w/Sel Column as MARK and I created the same field in my internal table.

And on the execution, I selected a row and that row is not getting the value as X for the field mark in my internal table. Please have a look at my code and guide me where I was going wrong.

Please note that GET CURSOR LINE doesn't suit for my requirement.

PROCESS BEFORE OUTPUT.
  MODULE status_2000.
  LOOP AT gt_main INTO gwa_main WITH CONTROL tc_main.
    MODULE fill_table_control.
  ENDLOOP.
*

PROCESS AFTER INPUT.
  LOOP AT gt_main.
    MODULE read_table_conrol.
  ENDLOOP.
  MODULE user_command_2000.

Before read control you need to modify the table control value with 'X'.

Hi,

i think its missing a modify inside a chain for each line.

Try following:


PROCESS AFTER INPUT.
  LOOP AT gt_main.
    CHAIN.
      gwa_main-mark.
      MODULE update_fields ON CHAIN-REQUEST.
    ENDCHAIN.
  ENDLOOP.
  MODULE read_table_conrol.
  MODULE user_command_2000.

MODULE update_fields INPUT.
  MODIFY gtmain
    FROM gwa_main
    INDEX tc_main-current_line.
ENDMODULE.


MODULE read_table_conrol INPUT.
  LOOP AT gt_main INTO gwa_main
    WHERE mark = 'X'.
    ...
  ENDLOOP.
ENDMODULE.

Regards,

Frisoni

In PAI

LOOP AT itab_table .

MODULE modify_int_table.

ENDLOOP.

In the MODULE call modify_int_table we can use

MODIFY int_table FROM workarea INDEX tab_con-CURRENT_LINE

i think this will solve your issue.

Hi Frisoni & Keshav,

I found out the problem. Instead of MARK, I made the field name as gwa_main-mark in the table control attributes and it is capturing now. And changed the code as below.

MODULE read_table_conrol INPUT.
  MODIFY gt_main FROM gwa_main INDEX tc_main-current_line.
ENDMODULE.

Thanks for your quick replies.

Yasin.
