Change Large Join to Selects (URGENT)

Question

Hi,
I need to change the following Join to a number of selects, since the Join isn't working as it should. Also, is "for all entries" obsolete or is it still relevant?
Here is the last part of the join, since I cannot list all of the fields:
  INTO TABLE itab_data
  from viqmelst as b
  inner join viqmfe   as c on bqmnum = cqmnum
  inner join viqmaml  as a on bqmnum = aqmnum and
                              cfenum = afenum
  inner join viqmur   as d on bqmnum = dqmnum and
                              cfenum = dfenum
  inner join viqmsm   as e on bqmnum = eqmnum and
                              cfenum = efenum
  inner join TJ02T    as f on bstat  = fistat
  WHERE a~qmnum in s_qmnum and
        a~qmdat in s_qmdat and
        a~qmart in s_QMART and
        a~matnr in s_matnr and
        b~stat  in s_stat and
        b~charg in s_charg and
        f~spras = 'EN'.
  sort itab_data by qmnum fenum.
  delete adjacent duplicates from itab_data.
Thanks,
John

Hi John,
The FOR ALL ENTIRES option is used to avoid the adverse impact on performence that the JOINS make..
Code like this:
SELECT xx yy zz...
INTO itab1
FROM tab1
WHERE.. Condtions of select options.
IF sy-subrc EQ 0
AND itab1[] IS NOT INITIAL.
SELECT aa bb cc
INTO itab2
FROM tab2
FOR ALL ENTRIES IN tab1
WHERE join codition with tab1
AND select conditions on fields of tab2 if any.
and so on for all other tables..
Thanks and Best Regards,
