Double click event in ALV

[Former Member]

Hello everybody,

I have an ALV report that uses the function module REUSE_ALV_GRID_DISPAY

to display the screen. I was wondering if there is a way to implementthe

double click event when using this FM. What I want the user to be abl to

do is to double click on a line in the ALV and have another ALV grid

display with a more detailed list. I know that the double click eventcan

be implemented using the object oriented approach using a container bu I

would like to avoid redoing the report to use the object oriented apprach.

Any help would be greatly appreciated.

you can code for it at user command, right ?

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

I_CALLBACK_PROGRAM = G_REPID

I_CALLBACK_USER_COMMAND = 'ZCALLBACK_USER_COMMAND'

........

now write a form for 'ZCALLBACK_USER_COMMAND'

FORM ZCALLBACK_USER_COMMAND USING UCOMM LIKE SY-UCOMM

RS_SELFIELD TYPE SLIS_SELFIELD.

(assuming t_output is your internal table with data.

case sy-ucomm.

when '&IC1'.

IF RS_SELFIELD-TABNAME EQ 'T_OUTPUT'.

READ TABLE T_OUTPUT INDEX RS_SELFIELD-TABINDEX.

Yes there is a way.

You have to call your function like this:

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

...

I_CALLBACK_PROGRAM = z_variant-report

(or your program name, not sy-repid because this will

change during the use of ALV Grid)

I_CALLBACK_USER_COMMAND = 'USER_COMMAND2'

(or some other name)

...

then you define your form:

form user_command2 using r_ucomm like sy-ucomm

rs_selfield type slis_selfield.

case r_ucomm.

when '&IC1'. (doubleclick)

if rs_selfield-tabindex > 0 and

rs_selfield-sumindex le 0.

read table itab into wa index

rs_selfield-tabindex.

perform second_grid.

endif.

endcase.

then your form for the second grid:

form second_grid.

(here you can make your selections for the second grid

based on the row you selected into workarea wa from the

first grid, and then call REUSE_ALV_GRID_DISPLAY again,

with another field catalog, internal table etc...)

endform.

good luck,

Hi Ashish, Here is the procedure to handle Interactive ALV. 1. declare events table like this.

data :
      i_events  type slis_t_event,
      w_events  like line of i_events.

2. Build events table .

w_events-name = 'USER_COMMAND' .
w_events-form = 'USER_COMMAND' .
append w_events to i_events.
clear w_events.

3. pass this events table through REUSE_ALV_GRID_DISPLAY. 4. USER_COMMAND call back subroutine should be like this in your case. This is nowhere called using PERFORM statement in ur program. 5. USER_COMMAND subroutine should be like this.

*&---------------------------------------------------------------------*
*&      Form  user_command
*&---------------------------------------------------------------------*
form user_command using ucomm like sy-ucomm
                  *selfield* type slis_selfield.
  case ucomm .
    when '&IC1'. This is for double click on ALV output.
      skip 10.
      position 10.
      write 'Double click was executed'.
  endcase.
 
endform.                    "user_command

selfield structure You can also handle Interactive ALV using this structure.

types: begin of slis_selfield,
         tabname              type slis_tabname,
         tabindex             like sy-tabix,
         sumindex             like sy-tabix,
         endsum(1)            type c,
         sel_tab_field        type slis_sel_tab_field,
         value                type slis_entry,
         before_action(1)     type c,
         after_action(1)      type c,
         refresh(1)           type c,
         col_stable(1)        type c,
         row_stable(1)        type c,
*        colwidth_optimize(1) type c,
         exit(1)              type c,
         fieldname            type slis_fieldname,
         grouplevel           type i,
         collect_from         type i,
         collect_to           type i,
       end of slis_selfield.

You have to check the above structure in debug when u double click what the above contains. very helpful structure fo ur case. I will come up with example. I hope that it helps u . Regards, Venkat.O
