Hi SAPAll.
here i have got one alv report ,when executing this alv report it displays in correct way but the only problem is when i click on the icon(local file) which exists at standard tool bar at the top to dowbload into local excel file it is raising the runtime error as
  The current statement requires a character-type data object.
at happened?
  Error in the ABAP Application Program
  The current ABAP program "SAPLKKBL" had to be terminated because it has
  come across a statement that unfortunately cannot be executed.
ror analysis
  At the statment
       "STRLEN( obj )..."
  , only character-type data objects are supported at the argument
  position "obj".
  In this particular case, the operand "obj" has the non-charcter-type type
  "P".

hi suhas .
the folliwing below is the code for alv and i had used 2 different structures for populating the data into alv
FORM fieldcat_init  USING    p_fieldcat TYPE slis_t_fieldcat_alv.
  DATA: ls_fieldcat TYPE slis_fieldcat_alv.
  CLEAR ls_fieldcat.
  ls_fieldcat-fieldname   = 'ORDER'.
  ls_fieldcat-ref_tabname = 'st_proc_out'.

  ls_fieldcat-seltext_s   = 'ORDER NUMBER'.
  ls_fieldcat-seltext_m   = 'ORDER NUMBER'.
  ls_fieldcat-seltext_l   = 'ORDER NUMBER'.
  APPEND ls_fieldcat TO p_fieldcat.
