ALV Variant chosen in grid

Question

Hi.
I have to following issue.
I have a program that through the use of additional buttons I added to my ALV grid can jump between different ALV grids.
The problem I'm having is that when you change the variant for ALV grid1 while viewing it and than change to grid 2, when you go back to grid1 the selected variant isn't used anymore.
So what I need is a way see check which variant is active when I get to the USER_COMMAND function of the ALV grid.
If someone has the answer to this I'd be very happy.
Regards,
Arthur

A. Parisius,
Do the following step so that you cant loose variant u set when u come to primary alv from secondary ALV.
1.
When you export I_SAVE = 'X' or 'A'  through REUSE_ALV_GEID_DISPLAY, you can save variant on ALV output.you can save different variants for one output.
2.
Define one parameter to select variant on selection-screen itself instead of selecting on Output.
parameters :p_layout like disvariant-variant.
3.
F4 help to get variants set for the report.
at selection-screen on value-request for p_layout.
  perform get_variant.
subroutine code and define w_variant structure type disvariant.
*&      Form  get_variant
form get_variant.
  data: lw_variant type disvariant,
          l_exit     type char1.
  lw_variant-report = sy-repid.
  call function 'REUSE_ALV_VARIANT_F4'
       exporting
            is_variant = lw_variant
            i_save     = 'A'
       importing
            e_exit     = l_exit
            es_variant = lw_variant
       exceptions
            not_found  = 2.
  if sy-subrc = 2.
    message id sy-msgid type 'S' number sy-msgno
            with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  else.
    if l_exit eq space.
      p_layout = lw_variant-variant.
      if not p_layout is initial.
        perform get_w_variant.
      endif.
    endif.
  endif.
endform.                    " get_variant
*&      Form  get_w_variant
form get_w_variant.
  w_variant-report      = sy-repid.
  w_variant-handle      = space.
  w_variant-log_group   = space.
  w_variant-username    = space.
  w_variant-variant     = p_layout.
  w_variant-text        = space.
  w_variant-dependvars  = space.
endform.                    " get_w_variant
4.
Pass w_variant structure through REUSE_ALV_GRID_DISPLAY FM .
CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'
  EXPORTING
    I_CALLBACK_PROGRAM      = 'ZVENKAT_TEST1' "Program name
    I_CALLBACK_USER_COMMAND = 'USER_COMMAND'
    IT_FIELDCAT             = i_field
    IT_SORT                 = i_sort
    I_SAVE                  = 'X'
    IS_VARIANT              = w_variant "If you pass variant selected on selection-screen
                                        "on F4 help,corresponding output is displayed
  TABLES
    T_OUTTAB                = <i_tab>
  EXCEPTIONS
    PROGRAM_ERROR           = 1
    OTHERS                  = 2.
IF SY-SUBRC <> 0.
  MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
          WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
5.
If you select variant and pass through FM it will be remained when u come back from secondary ALV..
I hope that it helps u .
