Answer 1

One program i wrote sometime ago had the following logic :
  select * from mbew into table t_mbew
    for all entries in t_mara
    where matnr = t_mara-matnr
      and bwkey in s-bwkey
      and bwtar in p-bwtar
      and ( bwtty = space or ( bwtty <> space and bwtar <> space ) ).
  sort t_mbew by matnr.
  select * from mseg
           join mkpf on mkpfmblnr = msegmblnr and
                        mkpfmjahr = msegmjahr
           into table t_mseg_mkpf
           for all entries in t_mbew
           where mkpf~budat >= p-budat-low
             and mseg~werks in s-werks
             and mseg~bwtar = t_mbew-bwtar
             and mseg~matnr = t_mbew-matnr.
  select * from bsim
           into table t_bsim
           for all entries in t_mbew
           where budat >= p-budat-low
             and bwkey in s-bwkey
             and bwtar = t_mbew-bwtar
             and matnr = t_mbew-matnr.
  loop at t_mbew into mbew.
    loop at t_bsim into bsim
         where matnr = mbew-matnr
           and bwkey = mbew-bwkey
           and bwtar = mbew-bwtar.
    endloop.
    loop at t_t001w into t001w
         where bwkey = mbew-bwkey.
      loop at t_mseg_mkpf
           where mseg-matnr = mbew-matnr
             and mseg-werks = t001w-werks
             and mseg-bwtar = mbew-bwtar.
      endloop.
    endloop.
  endloop.
Hope this may help you.
