Group by with for all entries
Hi,
SELECT max( VBELN ) VGBEL VGPOS POSNR FKIMG VRKME NTGEW MATNR ARKTX WERKS MVGR3
FROM VBRP
INTO TABLE T_INVIT
FOR ALL ENTRIES IN T_INVHD
WHERE VBELN = T_INVHD-VBELN
AND SPART = T_INVHD-SPART
AND werks IN swerks
AND mvgr3 IN smvgr3
group by VBELN VGBEL VGPOS POSNR FKIMG VRKME NTGEW MATNR ARKTX WERKS MVGR3.
i want to (max) invoice no against a delivery i.e vgbel but in this query i am getting error that with for all entries only count * is allowed.
regards
Fozia
Hi Do this way..
IF NOT T_INVHD[] is initial.
LOOP AT T_INVHD
SELECT max( VBELN ) VGBEL VGPOS POSNR FKIMG VRKME NTGEW MATNR ARKTX WERKS MVGR3
FROM VBRP
INTO T_INVIT
WHERE VBELN = T_INVHD-VBELN
AND SPART = T_INVHD-SPART
AND werks IN swerks
AND mvgr3 IN smvgr3
group by VGBEL VGPOS POSNR FKIMG VRKME NTGEW MATNR ARKTX WERKS MVGR3.
IF SY-SUBRC = 0.
APPEND T_INVIT.
CLEAR T_INVIT
ENDIF.
endselect.
endloop.
endif.
EVEN NO EFFECT ON PERFORMANCE

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
- Type: CHAR - Character String
ZMATERIAL:
- Length: 18
- Type: CHAR - Character String
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,
TorbenHi
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

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
DeepaHi 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.
With Regards

INNER JOIN with FOR ALL ENTRIES IN Performance ?

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

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,
BalajiHi 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,

Edited by: ABAP Techie on Sep 11, 2008 8:25 AMI 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.

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.

You can't expect miracles. With over a million entries in your itab any select is going to take a bit of time. Do you really need all these records in the itab? How many records is the select bringing back? I'm assuming that you have got and are using indexes on your ZEEDMT_ZMON table.
In this situation, I'd first of all try to think of another way of running the query and restricting the amount of data, but if this were not possible I'd just run it in the background and accept that it is going to take a long time.
