SELECT, NOT IN ?

Question

Hi,
is it OK to use NOT IN within SELECT statement?
data: lt_mara type STANDARD TABLE OF mara,
      wa_mara type mara.
select * from mara INTO TABLE lt_mara
         where matnr NOT IN ('F000018000', 'F000018100')
          AND mtart = 'FOLD'.
  loop AT lt_mara into wa_mara.
    write:/ wa_mara-matnr.
  endloop.
tnx, Adibo.

Answer 1

data: lt_mara type STANDARD TABLE OF mara,
      wa_mara type mara.
select-options:s_matnr for mara-matnr.
ranges : r_ranges for mara-matnr .
r_matnr-low  = 'F000018000'.
r_matnr-sign = 'E'.
r_matnr-options = EQ'.
append r_matnr.
r_matnr-low  = 'F000018100'.
r_matnr-sign = 'E'.
r_matnr-options = EQ'.
append r_matnr.
loop at s_matnr.
r_matnr-low  = s_matnr-low.
r_matnr-sign = 'E'.
r_matnr-options = EQ'.
append r_matnr.
endloop.
select * from mara INTO TABLE lt_mara
         where matnr in r_matnr
          AND mtart = 'FOLD'.
  loop AT lt_mara into wa_mara.
    write:/ wa_mara-matnr.
  endloop.
