Data changed and REUSE_ALV_GRID_DISPLAY

[Former Member]

Hi,

I have a problem for get the data which changed on my internal table : wlt_final

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_buffer_active         = space
      i_callback_program      = sy-repid
      I_CALLBACK_USER_COMMAND = c_user_command
      is_layout               = wa_alv_presentation
      i_structure_name        = 'ZTYPFAC'
      IT_FIELDCAT             = t_catalogue_pv[]
    TABLES
      T_OUTTAB                = wlt_final
    EXCEPTIONS
      PROGRAM_ERROR           = 1
      OTHERS                  = 2.

My Usercommand :

FORM USER_COMMAND USING F_UCOMM LIKE SY-UCOMM
                I_SELFIELD TYPE SLIS_SELFIELD.

  DATA: F_SUBRC LIKE SY-SUBRC,
        s_final like wls_final.

  READ TABLE wlt_final INDEX i_selfield-tabindex INTO s_final.
  break epetrini.
  CASE F_UCOMM.
    WHEN '&IC1'.
      CASE i_SELFIELD-SEL_TAB_FIELD.
        WHEN 'wlt_final-BELNR'.
          "CHECK NOT wlt_final-BELNR IS INITIAL.
          SET PARAMETER ID 'BLN' FIELD s_final-BELNR.

          CALL TRANSACTION 'FB03' AND SKIP FIRST SCREEN.

          "CHECK NOT wlt_final-BELNR IS INITIAL.
          SET PARAMETER ID 'VF' FIELD s_final-VBELN.
          CALL TRANSACTION 'VF03' AND SKIP FIRST SCREEN.
      ENDCASE.
    when '&DATA_SAVE'.
         data : wls_ZTYPFAC2 type ZTYPFAC2.
         break epetrini.
         loop at wlt_final into s_final where flag <> '' or MAJ = 'X'.
              clear wls_ZTYPFAC2.
              select single * from ZTYPFAC2 into wls_ZTYPFAC2 where VBELN = s_final-VBELN and BELNR = s_final-BELNR and MAJ = 'X'.
                if sy-subrc = 0.
                    update ZTYPFAC2
                    set FLAG  = s_final-FLAG
                        COMM  = s_final-COMM
                        uname = sy-uname
                        datem = sy-datum
                    where VBELN = s_final-VBELN and BELNR = s_final-BELNR.
                else.
                    wls_ZTYPFAC2-flag  = s_final-flag.
                    wls_ZTYPFAC2-VBELN = s_final-VBELN.
                    wls_ZTYPFAC2-BELNR = s_final-BELNR.
                    wls_ZTYPFAC2-COMM  = s_final-COMM.
                    wls_ZTYPFAC2-uname = sy-uname.
                    wls_ZTYPFAC2-datem = sy-datum.
                    wls_ZTYPFAC2-MAJ   = 'X'.
                    insert into ZTYPFAC2 values wls_ZTYPFAC2.
                endif.
         endloop.
  ENDCASE.
ENDFORM.                    "USER_COMMAND

Hi,

In your user command write the following code :

*&---------------------------------------------------------------------*
*&      Form  USER_COMMAND
*&---------------------------------------------------------------------*

FORM USER_COMMAND USING R_UCOMM LIKE SY-UCOMM
        RS_SELFIELD TYPE SLIS_SELFIELD.

  DATA : REF_GRID TYPE REF TO CL_GUI_ALV_GRID.

  DATA: L_VALID TYPE C.

*Code to reflect the changes done in the internal table

  IF REF_GRID IS INITIAL.
    CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
      IMPORTING
        E_GRID = REF_GRID.
  ENDIF.

  IF NOT REF_GRID IS INITIAL.

    CALL METHOD REF_GRID->CHECK_CHANGED_DATA
      IMPORTING
        E_VALID = L_VALID.

  ENDIF.
"After calling the above method and FM you will get the changed data from ALV
  CASE SY-UCOMM.

    WHEN 'FCODE'.
    "Write your code here
   ENDCASE.
ENDFORM.

Thanks & Regards,

Rock.

This was the answer I was searching for, yesterday I didn't found anything.

It works perfectly, I user  REUSE_ALV_GRID_DISPLAY as a popup (specifying coordinates) and when I finished (by pushing OK button and not INTRO before) data was unchanged at internal table. With your method it changes correctly.

Good work !!!!!!
