ALV Column Titles

Hi all,

Help me out pls.

i am displaying alv with correcy field and i need my own fieldlable instead dictionary fieldlable

  wa_fieldcat-fieldname = 'PSWBT_BAL'. " itab fieldname
  wa_fieldcat-tabname   = 'I_OUTPUT2'. " itab
  wa_fieldcat-ref_fieldname = 'PSWBT'.  "ref field
  wa_fieldcat-ref_tabname = 'BSID'.     "ref table
  wa_fieldcat-col_pos = 10.
  wa_fieldcat-do_sum = 'X'.
  wa_fieldcat-seltext_m = 'Balance'.  "my own fildlable
  append wa_fieldcat to i_fieldcat.
  clear wa_fieldcat.

note:

1) if i dont specify ref_fieldname ref_tabname, I can not get grand total at the end of column\

2) if i specify ref_fieldname ref_tabname, I can not get my own fieldlable 'Balance'.

<b>Question</b>

i need both grand total as well as my own fieldname.
