Disable / enable table control field at runtime

Question

hi ,
i am working on a custom transaction in which i have a table control...depending on a table value i have to disable an input field inside the table control...
i know in a normal field we use
loop at screen.
if screen- name = 'XXX' or screen-group = 'XXX'
screen-output = 0.
endif.
but inside a table control field how to modify it.

All you need to do is put some code in a module of your PBO.     This will change the cell attribute of a single row.
PROCESS BEFORE OUTPUT.
* PBO FLOW LOGIC FOR TABLECONTROL 'I_INTRCON'
* MODULE I_INTRCON_CHANGE_TC_ATTR.
* MODULE I_INTRCON_CHANGE_COL_ATTR.
  LOOP AT   I_INTR
       WITH CONTROL I_INTRCON
       CURSOR I_INTRCON-CURRENT_LINE.
<b>    MODULE I_INTRCON_CHANGE_FIELD_ATTR.</b>
  ENDLOOP.
  MODULE SET_CURSOR_FIELD.
  MODULE STATUS_0200.
module i_intrcon_change_field_attr output.                                                                               
modify i_intr index i_intrcon-current_line.                                                                               
if i_intr-check = 'X'.                                    
    loop at screen.                                         
      if screen-name = 'I_INTR-RCVQTY'.                     
        screen-input = '1'.                                 
      endif.                                                
      modify screen.                                        
    endloop.                                                
  endif.                                                                               
endmodule.
