My changes edited on editable ALV report are not transferring back to itab?

Question

Hello
I was developed a heirarchila editable ALV by using FM 'REUSE_ALV_HIERSEQ_LIST_DISPLAY'. The user will do some changes in the ITEMs (Z_VBAP_TABLE) on this heirarchila ALV report and presses the SAVE button.
In my program am handling this SAVE command and even my break point is also triggering at SAVE, but my ITAB is not having the CHANGED/new data!! still it has the old data in it! How to capture the user changes done on the report? those changes are not tranferring back to my itab/prog! because, ineed to update Z_VBAP_TABLE with those changes
Thank you

Hi Raju,
it is possible . But i know about your code.
   WHEN 'SAVE'(003).
    Lock the table
      CALL FUNCTION 'ENQUEUE_E_TABLE'
        EXPORTING
          mode_rstable   = 'E'
          tabname        = viewname
        EXCEPTIONS
          foreign_lock   = 1
          system_failure = 2
          OTHERS         = 3.
      IF sy-subrc <> 0.
        MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
                WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
      ENDIF.
      IF NOT grid1 IS INITIAL .
        CALL METHOD grid1->check_changed_data .
      ENDIF .
      SORT i_mod BY row.
      DELETE ADJACENT DUPLICATES  FROM i_mod COMPARING row.
      lh_norec = LINES( i_mod ).
      lh_total = lh_norec.
      SHIFT lh_total LEFT DELETING LEADING space.
Standard Table Update
      IF i_mod[] IS NOT INITIAL.
        LOOP AT i_mod INTO lwa_mod.
          READ TABLE <i_itab> INTO <wa_tab> INDEX lwa_mod-row.
          IF sy-subrc = 0 .
            IF lh_flag NE 'X'.
              MODIFY (viewname) FROM <wa_tab>.
            ELSE.
              INSERT (viewname) FROM <wa_tab>.
              IF sy-subrc NE 0.
                MESSAGE 'DATA NOT SAVED' type 'I'.
              ENDIF.
            ENDIF.
          ENDIF.
        ENDLOOP.
        CONCATENATE lh_total '  ' text-s01 INTO lh_succ SEPARATED BY space.
        MESSAGE 'Data Saved' TYPE 'I'.
This i did a long back. Check your code . I created an alv that will display data from my table . In this the user can click in any line item and he can change any value and press save  that will save the value .
