following is my code to display Total no.of lines in internal tables.

* total no. of records selected

   DESCRIBE TABLE <table> LINES ld_lines.

   ld_linesc = ld_lines.

   CONCATENATE text-004 ld_linesc

                     INTO t_line SEPARATED BY space.

   wa_header-typ  = 'A'.

   wa_header-info = t_line.

   APPEND wa_header TO t_header.
