Change and Save records on ALV List

Question

Hi,
i made alv list with fieldcatalog-edit to change records on alv list. But i want to save it to my dictionary table after changed. I think i should use dialog program to do that. The problem is how i can use dialog program.(i dont have an idea which user-command perform fields on alv list) I have used dialog programs before but i am new on this so i am not sure how i can do that. I will be pleased if you can help me.

Hello Masuke,
You have to code that in the AT- USER COMMAND event.
Follow the below sample code.
If the record is changed then track its index no.
        and populate it in an internal table for future
        action
          IF sy-subrc = 0 AND <dyn_wa> <> <l_wa>.
            <dyn_wa> = <l_wa>.
            i_index = rs_selfield-tabindex.
            APPEND i_index.
          ENDIF.
        ENDIF.      ENDIF.*   When save button is pressed
    WHEN 'SAVE'.*     Sort the index table
      SORT i_index.*     Delete all duplicate records
      DELETE ADJACENT DUPLICATES FROM i_index.      LOOP AT i_index.*       Find out the changes in the internal table
      and populate these changes in another internal table
        READ TABLE <dyn_table> ASSIGNING <dyn_wa> INDEX i_index.
        IF sy-subrc = 0.
          APPEND <dyn_wa> TO <dyn_tab_temp>.
        ENDIF.      ENDLOOP.*     Lock the table
      CALL FUNCTION 'ENQUEUE_E_TABLE'
        EXPORTING
          mode_rstable   = 'E'
          tabname        = p_table
        EXCEPTIONS
          foreign_lock   = 1
          system_failure = 2
          OTHERS         = 3.      IF sy-subrc = 0.*       Modify the database table with these changes
        MODIFY (p_table) FROM TABLE <dyn_tab_temp>.        REFRESH <dyn_tab_temp>.*       Unlock the table
        CALL FUNCTION 'DEQUEUE_E_TABLE'
          EXPORTING
            mode_rstable = 'E'
            tabname      = p_table.      ENDIF.
  ENDCASE.  rs_selfield-refresh = 'X'.
Hope it helps you.
Best Regards
