Hi,
TYPES:
  BEGIN OF my_struct,
    comp_a type i,
    comp_b type f,
  END OF my_struct.
DATA:
  my_data   TYPE my_struct,
  descr_ref TYPE ref to cl_abap_structdescr.
FIELD-SYMBOLS:
  <comp_wa> TYPE abap_compdescr.
START-OF-SELECTION.
  descr_ref ?= cl_abap_typedescr=>describe_by_data( my_data ).
  WRITE: / 'Typename     :', descr_ref->absolute_name.
  WRITE: / 'Kind         :', descr_ref->type_kind.
  WRITE: / 'Length       :', descr_ref->length.
  WRITE: / 'Decimals     :', descr_ref->decimals.
  WRITE: / 'Struct Kind  :', descr_ref->struct_kind.
  WRITE: / 'Components'.
  WRITE: / 'Name              Kind   Length   Decimals'.
  LOOP AT descr_ref->components ASSIGNING <comp_wa>.
    WRITE: / <comp_wa>-name, <comp_wa>-type_kind,
             <comp_wa>-length, <comp_wa>-decimals.
  ENDLOOP.
