Double Click on ALV Grid

Question

Hi,
I have this doubt regarding ALV grid display.
I am displaying a list using REUSE_ALV_GRID_DISPLAY.
I need to go to a transaction when i double click on a particular line on the output list based on the content of the 1st cell of that line. (ie if i have 4 columns and 5 records and click on the 3rd column of 2nd record then i need to know the value of the 1st field of the 2nd record)
I am using a call back user command subroutine to capture the index and the field which has been clicked upon. This index is giving perfect result by which I am reading the output table and doing the later operations.
But what if i sort the list in ALV by any column? Then the index that I will get on double clicking will correspond to the index on the screen but not to the index on my internal output table. In that case I will get a wrong value of the 1st field.
I do not want to use OO alv. Is there a way to handle this situation?
Regards,

Hello Shinjan,
When i display an output table say t_out on ALV GRID, the records in the table shown on the grid is identical to what i have in t_out. Hence the tabindex will correspond to that very record in t_out.
But when i sort the table on the grid, the order of the rows changes... so for example a row which had index 2 will now have an index 6 (say). So on clicking this record, the tabindex will be 6 where as the same record exist in 2nd position in t_out. How to handle this?

Did you try this scenario? Your output table t_out also gets refarranged after SORT. Good thing is you DONOT have to code anything for this )
As per your example the table t_out will be rearranged so that the initial 2nd record will be at 6th posn.
FORM f_user_command  USING   fp_v_ucomm   TYPE syucomm
                             fp_selfield  TYPE slis_selfield."#EC CALLED
  CONSTANTS:
          l_c_ic1           TYPE char4 VALUE '&IC1',
          l_c_vl            TYPE char2 VALUE 'VL',
          l_c_vl03n         TYPE char5 VALUE 'VL03N'.
  CASE fp_v_ucomm.
* Ok code for double code
    WHEN l_c_ic1.
      IF fp_selfield-tabindex NE space.
        READ TABLE it_final INTO wa_final           "it_final gets rearranged as per the SORT condition
                               INDEX fp_selfield-tabindex. "tabindex keeps the correct index after SORT
        SET PARAMETER ID l_c_vl FIELD wa_final-vbeln.
        CALL TRANSACTION l_c_vl03n AND SKIP FIRST SCREEN.
      ENDIF.
  ENDCASE.
ENDFORM.                    "f_user_command
