TABLES spfli. DATA: lt_data TYPE STANDARD TABLE OF spfli, lwa_ref TYPE REF TO data, lt_fields TYPE stringtab, desc_struc TYPE REF TO cl_abap_structdescr, desc_fields TYPE ddfields. FIELD-SYMBOLS: <fs_data> TYPE any, <p_str> TYPE string, <p_component> TYPE dfies. CREATE DATA lwa_ref LIKE LINE OF lt_data.
