Issue with FOR ALL ENTRIES

Hi All,
I have used FOR ALL ENTRIES statement in while selecting data based on some other internal table (to avoid select within loop).
While using FOR ALL ENTRIES, the target table (internal table in which data is getting stored) is getting affected.
The other fields are becoming zero and several rows gets delerted from the internal table after performing select query.
How to avoid this bug?
Kindly help me out....
Regards
Pavan

hi after the for all entries statement did you used the read statement .
if not you will not get any data ..check this program..
tables:mara,marc.
data:begin of itab occurs 0,
     matnr like mara-matnr,
     end of itab.
data:begin of itab1 occurs 0,
     matnr like marc-matnr,
     werks like marc-werks,
     end of itab1.
select   matnr
      from mara
      into corresponding fields of  table itab.
      if   itab is initial.
      select  matnr
              werks
             from marc
             into  table itab1
             for all entries in itab
             where matnr = itab-matnr.
             loop at itab1.
             read table itab with key matnr = itab-matnr.
             write:/ itab1-matnr,itab1-werks.
             endloop.
             endif.

  • Replacing a inner join with for all entries

    Hi Team,
       In a already developed program I am replacing a inner join with select query follow up with for-all-entris and passing the data to final internal table but in both the case the result should be same then only my replacement will be correct. But my no records in both cases differs. This happening because when i am selecting data from first data base table is 32 lines. then I am doing fo-all-entries moving all the duplicate entries then the no records are four. but in final internal table i am looping the first internal table. So in final internal table the no of records are 32. But in inner join query the records are 16.So please let me know how resolve this issue?
    Thanks and REgards

    Hi Thomas,
      Thanks for ur suggestion.
    The solved that in below.
    In select query I did not change anything The way I had written the code was correct.
    I think many of us know how to write that how to make the performance better in that way.
    I made the change when I transfered the to final internal table.
    The original Inner join code:
    select a~field1 a~field2 a~field3 b~field2 b~field3 b~field4
               from dbtab1 as a  inner join dbtab2 as b
              on a~field1 = b~field1 into it_final where
              a~field1 in s_field1. [Field1  in both the table are key field]
    Before code:
    Sort itab1 by key-fields.
    sort itab2 by keyfields.
    loop at itab1 into wa1.
    move: wa1-field1 to wa_final-field1,
               wa1-field2 to wa_final-field2,
               wa1-field3 to wa_final-field3.
    read table itab2 into wa2 witk key field1 = wa1-field1 binary search.
      if sy-subrc = 0.
      move : wa2-field2 to wa_final-field4,
                 wa2-field3 to wa_final-field5,
                 wa2-field4 to wa_final-field6.
    append wa_final to it_final.
    endif.
    Clear : wa1, wa2, wa_final.
    endloop.
    In this case if the one key fieild value is not present there in second internal table but its there in first internal table still it will read that row with 2nd internal values having zeroes. Normally what does not happen in inner join case if the key field value will same in both the case ,then that will fetch only those rows.
    Changed Code
    loop at itab1 into wa1.
    read table itab2 into wa2 witk key field1 = wa1-field1 binary search.
      if sy-subrc = 0.
    move: wa1-field1 to wa_final-field1,
               wa1-field2 to wa_final-field2,
               wa1-field3 to wa_final-field3.
      move : wa2-field2 to wa_final-field4,
                 wa2-field3 to wa_final-field5,
                 wa2-field4 to wa_final-field6.
    append wa_final to it_final.
    endif.
    Clear : wa1, wa2, wa_final.
    endloop.
    In this case the values will read to final internal table if both key field matches.

  • Can we use inner joins with for all entries?

    Hi,
        Can we use innerjoin on two tables MARA and MAKT against the materials in
        the  internal table.
        If so ,please let me know whether there is performance issue.Because if there is
        bad performance issue or something else like thise means,my project manager
        wont allow to include.
        So can one let me know about this.
    Thanks,
    Balaji

    Hi Arunkumar,
                               I think you are not clear.My question is can I use innerjoin with
    for all entries.For example below is my code.
    SELECT A~MATNR
             B~MAKTX
             A~MTART
             A~MATKL
             FROM MARA AS A INNER JOIN MAKT AS B
             ON AMATNR = BMATNR
             INTO TABLE IT_MARA_MAKT
             FOR ALL ENTRIES IN IT_MATNR
             WHERE A~MATNR = IT_MATNR-MATNR
             AND   A~EXTWG = P_EXTWG
             AND   A~SPART = P_SPART.
    Can we use like this for all entries along with innerjoins.
    Thanks,

  • Alternative for / Problems with: "For all entries in data_package"

    Hi Guys
    I doing some ABAP in a Start Rotine in BW and would like to do the following:
      select * from /BI0/PMATERIAL into table 0mat
      for all entries in DATA_PACKAGE
      where material = DATA_PACKAGE-/bic/zmaterial.
    But I get the following error:
    E:When using the addition "FOR ALL ENTRIES IN itab", the fields "MATERIAL" and "DATA_PACKAGE-/BIC/ZMATERIAL" must have the same type and length. and length.
    ZMATERIAL:
    - Length: 28

    ZMATERIAL:

    According to the error message "For all entries" cannot be used in this case since the lengths are not identical, but is there an alternative way to do what I would like to do?
    Thanks in advance, kind regards,
    Torben

    Hi
    one thing you can try like this define one variable in other itab of same type
    then loop at the first table and assign it to new field and modify the itab
    then use this field with for all entries

  • Using aggregate function along with for all entries: sugest alternative

    My requirement:
    For each record in i_vbap for which 'charg' is initial, need to determine batch using the following logic:
    For the material (MATNR) in i_vbap, select the batch (CHARG) which has the largest (MAX) unrestricted inventory quantity (CLABS) from MCHB table.
    How do I implement this logic without using select statement inside a loop as I cannot use MAX ( CLABS ) function along with FOR ALL ENTRIES in a SELECT?
    Suggest an alternative.

    For each record in i_vbap for which 'charg' is initial ,fetch all the existing 'clabs' value.
    [ Remember to include all the key fields in selct ]
    Sort the new table .
    Put a loop,use at end of 'charg' and append to another table. U get ur solution
    I think this should be the most economic way to do so.

  • How does select stmt with for all entries uses Indexes

    Hello all,
    I goes through a number of documents but still confused how does select for all entries uses indexes if fields are not in sequences. i got pretty much the same results if i take like two cases on Hr tables HRP1000 and HRP1001(with for all entries based upon hrp1000). Here is the sequence of index fields on hrp1001 (MANDT, OTYPE, OBJID, PLVAR, RSIGN, RELAT, ISTAT, PRIOX, BEGDA, ENDDA, VARYF, SEQNR). in second case objid field is in sequence as in defined Index but i dont see significant increase in field even though the number of records are around 30000. My question is does it make a differrence to use field sequence (same as in table indexes) in comparison to redundant field sequence (not same as defined in table indexes), secondly how we can ge tto know if table index is used in Select for entries query i tried Explain in ST05 but its not clear if it uses any index at all in hrp1001 read.
    here is the sample code i use to get test results.

    Thank you for your answer, its very helpful but i am still nor sure how does parameter rsdb/max_blocking_factor affect records size.
    Hi,
    The blocking affects the size of the statement and the memory structures for returning the result.
    So if your itab has 500 rows and your blocking is 5, the very same statement will be executed 100 times.
    Nothing good or bad about this so far.
    Assume, your average result for an inlist 5 statement is 25 records with an average size of 109 bytes.
    You average result size will be 2725 byte plus overhead which will nearly perfectly fit into two 1500 byte ethernet frames.
    Nothing to do in this case.
    Assume your average result for an inlist 5 statement is 7 records with an average size of 67 bytes.
    You average result size will be ~ 470 byte plus overhead which will only fill 1/3 of a 1500 byte ethernet frame.
    In this case, setting the blocking to 12 ... 15 will give you 66% network transfer performance gain,
    and reduces the number of calls to the DB by 50%, giving additional benefit.
    Now this is an extreme example. The longer the average row length is, the lower will be the average loss in the network.
    You have the same effects in memory structures, but on that layer you are fighting single micro seconds instead of
    hundreds of these, so in real life it is rarely measurable.
    Depending on table-statistics, oracle might decide for short inlists to use a concatanation instead of an inlist.
    This is supposed to be more costy, but I never had a case where I could proove a big difference.
    Values from 5 to 15 for blocking seem to be ok for me. If you have special statements in customer coding,
    it #might# be benefitial to do the mentioned calculations and do some network tracing to see if you can squeeze your
    network efficiency by tuning the blocking.
    If you have jumbo frames enabled, it might be worth to be analyzed as well.
    If you are only on a DB-CI system that is loopback connected to the DB, I doubt there might be a big outcome.
    Hope this helps

    I found this in the F1-Help for "FOR ALL ENTRIES":
    >"In Release 6.10 and higher, the same internal table can be specified after FOR ALL ENTRIES and after INTO."
    Check however if you can use a proper JOIN select. This will fill your internal table in one operation and is usually faster than a FOR ALL ENTRIES, contrary to some circulating comments here.

    best practise ... don't know ... it is allowed and o.k.
    If possible you should of coourse to have no FOR ALL ENTRIES at all !
    Joins, there is no general rule, check indexes etc.
    The first SORT, I don't that it help for anything, use it together with the delete adjacent duplicates if you expect duplicates in the driver table.
    o.k., it can help, if there is a loop afterwards and an append inside, because the new table itab1 is then sorted.

      SELECT avbeln aposnr amatnr apstyv a~werks
        FROM vbap AS a INNER JOIN marc AS b
                               ON amatnr = bmatnr AND
                                  awerks = bwerks
        INTO TABLE vbap_itab
       WHERE a~vbeln = i_vbeln-vbeln
         AND a~uepos = 0
         AND b~umrsl = 'VBOM'.
    and please tell me which table we need to select first in vbap and marc and why

    hi check this one
    data:
           begin of  vbap_itab,
           vbeln  type vbap_-vbeln,
           posnr type vbap_posnr,
           matnr type vbap_matnr,
           pstyv  type vbap_pstvy,
           werks type vbap_werks,        
           end of itab,
           begin of marc_itab,
              matnr type marc-matnr,
              werks type marc-werks,
          end of marc_itab.
    select matnr
              werks
       from marc
       into table marc-itab
    where umrsl = 'VBOM'.
    if marc_itab is initial.
    exit.
    else.
    select vbeln
              posnr
             matnr
             pstvy
             werks
      from vbap
      into  table vbap_itab
    for all entries in marc_itab
    where matnr = marc_itab-matnr
          and    werks = marc_itab-werks
          and  vbeln = i_vbeln-vbeln
          and uepos = 0.
    endif.

    Hi Karthik,
         Thanx  a   ton....
          How  about   the  below   approach  .....its   allowed  &   working  fine ....also  simplifying  my  work..
              SELECT  matnr  menge  rsnum  rspos
                      INTO  (ws-matnr, ws-menge, ws-rsnum, ws-rspos)
                      FROM   mseg

                        AND  bwart = mvtyp1
                        AND  rsnum = iresb-rsnum
                        AND  rspos = iresb-rspos.
                      imseg2-matnr =  ws-matnr.
                      imseg2-menge =  ws-menge.
                      imseg2-rsnum =  ws-rsnum.

  • Performance issue fetching huge number of record with "FOR ALL ENTRIES"

    Hello,
    We need to extract an huge amount of data (about 1.000.000 records) from VBEP table, which overall dimension is about 120 milions records.
    We actually use this statements:
    CHECK NOT ( it_massive_vbep[] IS INITIAL ) .
    SELECT (list of fields) FROM vbep JOIN vbap
                 ON vbepvbeln = vbapvbeln AND
                  vbepposnr = vbapposnr
                 INTO CORRESPONDING FIELDS OF  w_sched
                 FOR ALL ENTRIES IN it_massive_vbep
                 WHERE    vbep~vbeln   = it_massive_vbep-tabkey-vbeln
                    AND    vbep~posnr   = it_massive_vbep-tabkey-posnr
                    AND    vbep~etenr   = it_massive_vbep-tabkey-etenr.
    notice that internal table it_massive_vbep contains always records with fully specified key.
    Do you think this query could be further optimized?
    many thanks,
    -Enrico

    the are 2 option to improve performance:
    + you should work in blocks of 10.000 to 50.000
    + you should check archiving options, does this really make sense
    > VBEP table, which overall dimension is about 120 milions records.
    it_massive_vbep  into it_vbep_notsomassive (it_vbep_2)
    CHECK NOT ( it_vbep_2[] IS INITIAL ) .
      get runtime field start.
    SELECT (+list of fields+)
                  INTO CORRESPONDING FIELDS OF TABLE w_sched
                  FROM vbep JOIN vbap
                  ON vbep~vbeln = vbap~vbeln AND
                       vbep~posnr = vbap~posnr
                  FOR ALL ENTRIES IN it_vbep_2
                  WHERE vbep~vbeln = it_vbep_2-vbeln
                  AND      vbep~posnr = it_vbep_2-posnr
                  AND      vbep~etenr  = it_vbep_2-etenr.
      get runtime field stop.
    t = stop - start.
    write: / t.
    Be aware that even 10.000 will take some time.
    Other question, how did you get the 1.000.000 records in it_massive_vbep. They are not typed in, but somehow select.
    Change the FAE into a JOIN and it will be much faster.

  • Performance issue in 'Selelect statement with for all entries'

    Hi,
      The following SELECT statement is taking too much time.
             SELECT * FROM /rb04/yc5_mver
             INTO TABLE g_it_mver
             FOR ALL ENTRIES IN l_it_inva
             WHERE matnr EQ l_it_inva-matnr  AND
                          werks EQ l_it_inva-werks  AND
                          indei EQ l_it_inva-indei  AND
                          gjahr IN g_r_gjahr.
         Internal table l_it_inva is having too many records.
        Is there any way to optimize it.
    Regards,
    Tintu

    Hi Tintu,
    check table  l_it_inva for initial.
    sort internal table  l_it_inva with key  matnr werks indei gjahr.
    delete adjacent duplicates from  l_it_inva comparing   matnr werks indei gjahr.
    Then use following select query.
    SELECT * FROM /rb04/yc5_mver
    INTO TABLE g_it_mver
    FOR ALL ENTRIES IN l_it_inva
    WHERE matnr EQ l_it_inva-matnr AND
    werks EQ l_it_inva-werks AND
    indei EQ l_it_inva-indei AND
    gjahr IN g_r_gjahr.
