* using function module below are the inputs i am passing.

CALLFUNCTION'TEXT_CONVERT_CSV_TO_SAP'

       i_field_seperator    = ','

       i_line_header        = 'X'

      i_tab_raw_data       = pa_file3

    TABLES

       i_tab_converted_data = gt_fgfile

     EXCEPTIONS

       conversion_failed    = 1

       OTHERS               = 2.

     IF sy-subrc <> 0.
