Correspondence - problem in sort variant

Question

I run program RFFOAVIS_FPAYM for Correspondence .
I define in spro sort variant for the program and specific payment method without any sort ! ! ! !
I choose specific sort variant.
but the program always get the sort from REGUH-SRTF2.
there's the code from include RFFORI99:
IF NOT REGUH-SRTF2 IS INITIAL.
HLP_SORTH1 = REGUH-SRTF2(16).
HLP_SORTH2 = REGUH-SRTF2+16(16).
HLP_SORTH3 = REGUH-SRTF2+32(16).
ELSE.
T021M = HLP_T021M_H.
DO 3 TIMES.
CASE SY-INDEX.
WHEN 1.
PERFORM SORTIERUNG_ASSIGN USING
T021M-TNAM1 T021M-FELD1 T021M-OFFS1 T021M-LENG1 HLP_SORTH1.
WHEN 2.
PERFORM SORTIERUNG_ASSIGN USING
T021M-TNAM2 T021M-FELD2 T021M-OFFS2 T021M-LENG2 HLP_SORTH2.
WHEN 3.
PERFORM SORTIERUNG_ASSIGN USING
T021M-TNAM3 T021M-FELD3 T021M-OFFS3 T021M-LENG3 HLP_SORTH3.
ENDCASE.
ENDDO.
ENDIF.
the field REGUH-SRTF2 is always not initial.
and the program get the sort from this field and
not from the sort variant parameter from the program.
how can make to the field to be initial ? ? ? ? ? ?

Hi
as per my knowledge there is slight diff between type and like keywords
type key refer the data type of a field where as like key refer the reference of existing  internal table in this just refer the data types not content(data)
example:
types:BEGIN OF ty_itab,
      matnr type mara-matnr,
      matkl type mara-matkl,
      mbrsh type mara-mbrsh,
      ersda type mara-ersda,
  END OF ty_itab.
  data:itab type STANDARD TABLE OF ty_itab.
  data:wa_itab type ty_itab.
we want to create one more internal table with the existing structure  at this time  we will go through the like keyword.
jtab like itab occurs 10.
and also check the following code.
REPORT  sort.
types:BEGIN OF ty_itab,
      matnr type mara-matnr,
      matkl type mara-matkl,
      mbrsh type mara-mbrsh,
      ersda type mara-ersda,
  END OF ty_itab.
data:itab type STANDARD TABLE OF ty_itab.
  data:wa_itab type ty_itab.
  select matnr matkl mbrsh ersda from mara into wa_itab.
    APPEND wa_itab to itab.
ENDSELECT.
SORT itab by mbrsh.
write:/ 'matno',' mat group','industry sector','created on'.
loop at itab into wa_itab.
  write:/ wa_itab-matnr,wa_itab-matkl,wa_itab-mbrsh,wa_itab-ersda.
  endloop.
