alv

[Former Member]

Hi all,

i have alv with fields . ID IDdescription .... etc.

now my ID field is editable but the IDdescription is ony display. but this field should be internaly editable .... ie. when i select ID value ... it should automatically populate the IDdescription with text.

in my prog i have modified the fieldcatalog to for the EDIT field to no edit(space) value. and have internally handeled the events to populate the IDdescription with long text.

*problem : although the internal table for the alv is populated with the IDdescription value ... it dose not display it in the alv.*

can someone help.

thanks.

sounds like you need to refresh.

Hi,

Create a SAVE button in pf status and when user clicks this button then save data in internal table as well as modify alv output.

Refer this program:-

  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
   EXPORTING
     i_callback_program                = v_rep_id       " report id
     i_callback_pf_status_set          = 'PF'           " for PF-STATUS
     i_callback_user_command           = 'USER_COMMAND' " for User-Command
     is_layout                         = wa_layout      " for layout
     it_fieldcat                       = it_field       " field catalog
     it_sort                           = it_sort        " sort info
    TABLES
      t_outtab                          = it_final      " internal table
   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.

  CASE lv_okcode.

* when the function code is SAVE then save records into internal table
    WHEN 'SAVE'.

      ENDIF.

  ENDCASE.
