Hi Ravi,
1. To check performance of a report we use the perfromance trace. The transaction code is ST05.
You can also refer the link :
http://help.sap.com/saphelp_erp2005/helpdata/en/8a/3b834014d26f1de10000000a1550b0/content.htm
2. Also we can do the run time analysis of the code uising transaction code SE30.
3. To do a general check on the code , you can use the SAP Code Inspector. The transaction code for this is SCI. This will defentely give you a detailed analysis of the program.
4 . To have a general idea about the performance tuning of a report , you should refer the link :
http://www.sapgenie.com/abap/performance.htm.
Hope this solves yopur query.

Kunal.

How to Join two tables using the Inner Join

Hi All,
I have two tables i.e table1 and table2 as i have created two otds and my present requirement is to join this two tables and get the results and using this i need to do some logic and update another table3.
can some one help me out how to go for the above req.
Thanks in Advance
Srikanth

The best efficient way to use inner join is create two input otds,use there otd's in create a collaboration usinf etl.
after selecting two input otd's create a inner join statement and map it to out put otd.
while using the etl the performance of the over all integration is increased 20 time of the normal integration.
Hopes this will helps,,
Thanks,

Issue with the inner join on EKKO and EKPO.

Dear All,
The report using this join takes a long time to execute.
Does this inner join have an issue?
Do i need to code this in a different way for lesser execution time?
Please give me your inputs.

Index EKKO~D consists top-down of BSTYP and BEDAT. BSTYP is already an EQ-condition in your selection, but not very selective (many rows with the same value). So including BEDAT should help in efficiently reducing the data that needs to be scanned for finding the relevant rows. However, just a new optional S_BEDAT select option that can be left empty by the user would not help, you must force a narrow selection (one month, one week, even one day? the less the better).
This is just a quick guess from my side, there might be other options that occur to you once you have analysed the available indexes. Sometimes alternative tables could be the solution, and even less sometimes introducing a new secondary index for a standard table might be the last option (takes up space and adds processing time to insert/update/delete operations).

Please tell me the Three table INNER JOIN Sql statement

Hi experts,
I got requirement like by using INNER JOIN i have to write the code in MY program i.e using 3 tables VBAK VBAP and VBUK.And the common field is VBELN .SO please give the INNER JOIN SQL statement for above three tables...

Inner Join of 3 tables is correct or not?

Hi Guys ,
             I have a requirement where i have to join 3 tables i dont know whether the inner Join which i wrote for 3 tables is correct or not.I am not getting any Syntax error but whether the logci below which i wrote gets all the records or not.
The Requirement is
"c.     Select the BOL Number entered in the screen and query the table LIKP with the BOL number in the field LIKP-BOLNR. Gather the list of ALL delivery documents (LIKP-VBELN) that is outputted.
d.     Query the list of the delivery documents obtained into the table VBFA in the field VBFA- VBELV. From the output that is displayed, select the Follow-On Document Field (VBFA-VBELN) for that item whose Subsequent Document Category (VBFA- VBTYP_N) is R and the Movement Type (VBFA- BWART) is 641. Get the Follow-On document number for each of the above Delivery Document number.
e.     Query the table EKBE with the Follow On document obtained above in the field Material Document (EKBE- BELNR). Perform this activity for each of the follow on document obtained above. Get the resultant Purchase Order (EKBE-EBELN) and Item Number (EKBE-EBELP) from the query. After querying will all the Follow-On Documents, get the unique list of PO number and Item Number.
The logic which i wrote is
                Begin of t_PoolSTO_out,
              BOLNR type LIKP-BOLNR,
              EBELN type EKBE-EBELN,
              EBELP type EKBE-EBELP,
              VBELN type LIKP-VBELN,
              VBELNV type VBFA-VBELN,
         End of t_PoolSTO_out.
      Data: i_PoolSTO type Standard table of t_PoolSTO_out.
Select
        a~BOLNR
        c~EBELN
        c~EBELP
        a~VBELN
        b~VBELN
        from LIKP as a
        Inner Join VBFA as b on aVBELN = bVBELV
        Inner Join EKBE as c on bVBELN = cBELNR
        into Table i_PoolSTO
        Where a~BOLNR in S_LBLNE and
              b~VBTYP_N = 'R' and
              b~BWART = '641'.
          My doubt is whether the logic works or not i Mean does i getall the rrecords based on the requirement.?
                  If not please tell any alternative logic?
Thanks,
Gopi Anne.

Hi Gopi,
Your code is Good.
But try to avoid Inner join with more number of Tables ...because this is a performance issue..
try to use..
select (primary key fields mainly,other fields) from LIKP into itab where bolnr in p_bolnr(paramater).
next try to use for all entries option..
select (primary key fields mainly,other fields) from VBFA for all entries in itab where (give the condition)....
simillarly do for the other select ....ok this will try to reduce the performance issue....

How to inner join attribuet from user with system resource on sccm 2012 query

Hi , I am using SCCM 2012. Trying to create a WQL query to get list of computers with department name and netbios names,etc. these are in USER and SYSTEM RESOURCE object type seperately. The query wizard doesn't allow me to choose sytem
resource and USER attribute at same time. In JOIN, the inner join also doesn't have SYSTEM RESOURCE attribute class for me to join it with USER attribute class. Any way to resolve this issue so that I can get a query as mentioned?
I tried the wql below and pasted to my test query, it gave an error. I guess it's because that wql is on sccm2007.
Please advise,thanks!

Inner join on four tables

hi all,
i am facing the problem with the inner join in the select query for 4 tables.
can i use the inner join for tables in SAP 6.0 version,
it is going to dump.
here is my code
SELECT DISTINCT apernr abegda aendda awagetype aamount acurrency
        altrctry brufnm banred bvorna bnachn cgroupcode d~vdsk1
FROM pa9011 AS a INNER JOIN pa0002 AS b ON bpernr = apernr
                  INNER JOIN pa9013 AS c ON cpernr = bpernr
                  inner join pa0001 as d on dpernr = cpernr
                  INTO CORRESPONDING FIELDS OF TABLE it_bonus
WHERE a~pernr IN s_pernr AND
       a~begda IN s_date AND
       a~subty EQ s_subty AND
       a~wagetype EQ wa_perbonus AND
       a~ltrctry = gc_ind AND
       a~amount > 0 AND
       b~endda = '99991231' AND

       c~endda = '99991231' and
       d~endda = '99991231'
    ORDER BY a~pernr.

hi this is the dump ,
In a SELECT access, the read file could not be placed in the target
field provided.
Either the conversion is not supported for the type of the target field,
the target field is too small to include the value, or the data does not
have the format required for the target field.

Confusion in Select query having a inner join on single table

Hi,
I was going through coding and came a accross a select query which has a inner join on a single table. I am getting confused while analysing this . Please someone can help me analysing this query.
select
        m~MATERIAL
        s~NUMERATOR s~DENOMINTR
        m~GROSS_WT m~UNIT_OF_WT
      into table itab
      from ( table1as s
       inner join table1 as m
       on m~MATERIAL = s~MATERIAL
      and m~MAT_UNIT = 'CS'
      and m~SOURSYSTEM = s~SOURSYSTEM )
      where s~MAT_UNIT = 'EA'
         and s~SOURSYSTEM = 'LD'
         and s~OBJVERS = 'A'
         and s~MATERIAL IN ( Select mat_sales
            from Table2 group by mat_sales ).
Thank you
Kusuma

I don't see any use of the INNER JOIN here.
But what's the meaning of the last selection clause?
s~MATERIAL IN ( Select mat_sales
            from Table2 group by mat_sales ).
Is that native SQL or something?

Are inner join and equijoin are same....?

are inner join and equijoin are same....?

WhiteHat wrote:
interesting it says that - an equi join is a type of inner join but you can't really say they are the same thing.Simply said it it like this:
Equi join means compare two tables where a value is in each table using an equal sign.
An inner join means: We use the INNER JOIN keyword and have a join condition between the two tables.
example1
select *
from emp
inner join dept on emp.dept_no = dept.dept_no;This example is an inner join and also an equi join.
example2
select *
from emp
inner join dept on emp.dept_no >= dept.dept_no;This example is an inner join which is NOT an equi join.
How to interpret the outcome is a different story (in this case it doesn't make much sense). However the syntax is correct and it is an inner join. But since it doesn't use the equal operator it is an non-equi join.

Inner join query used with 7 Database tables

HI All,
In a report they used the Inner join Query with 6 Data base table..now there is a performance issue with at query.
its taking so much of time to trigger that query. Please help how to avoid that performance issue for that.
In that 2 database tables containing lakhs of records..
According to my knowledge it can be avoided by using secondary indexs for those 2 database tables..
and by replacing the Inner join Query with FOR ALL ENTRIES statement.
i want how to use the logic by using FORALL ENTRIES statement for this..
So, please give you proper suggestion to avoid this issue..
Thanking you.

Hi,
And what do you mean with "they used"? If "SAP used" then yo will need to ask a SAP for note
FOR ALL ENTRIES is quite good described in help. Please search forum also.
Without query it won't be possible to tell how it can be optimized, however you can try to use SE30/SAT and ST05. Maybe it will help you.

Need help with inner join and distinct rows

Hey Guys,
i have
1) BaseEnv Table
2) Link Table
3) BaseData Table
Link table has three columns Id,BaseEnvId,BaseDataId
the BaseEnvID is unique in the table where as BaseDataId can be repeated i.e multile rows of BaseEnv Table can point to same BaseData table row
Now i want to do BaseEnvTable inner join Link Table inner join BaseData Table and select 5 columsn ; Name,SyncName,Version,PPO,DOM from the BaseData table.. the problem is that after i do the inner join I get duplciate records..
i want to eliminate the duplicate records , can any one help me here

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums. Now we have to guess and type, guess and type, etc. because of your bad manners.
CREATE TABLE Base_Env
(base_env_id CHAR(10) NOT NULL PRIMARY KEY,
Think about the name Base_Data; do you have lots of tables without data? Silly, unh?
CREATE TABLE Base_Data
(base_data_id CHAR(10) NOT NULL PRIMARY KEY,
Your Links table is wrong in concept and implementation. The term “link” refers to a pointer chain structure used in network databases and makes no sense in RDBMS. There is no generic, magic, universal “id” in RDBMS! People that do this are called “id-iots”
in SQL slang.
We can model a particular relationship in a table by referencing the keys in other tables. But we need to know if the relationship is 1:1, 1:m, or n:m. This is the membership of the relationship. Your narrative implies this:
CREATE TABLE Links
(base_env_id CHAR(10) NOT NULL UNIQUE
REFERENCES Base_Env (base_env_id),
base_data_id CHAR(10) NOT NULL
REFERENCES Base_Data (base_data_id));
>> The base_env_id is unique in the table where as base_data_id can be repeated I.e multiple rows of Base_Env Table can point [sic] to same Base_Data table row. <<
Again, RDBMS has no pointers! We have referenced an referencing tables. This is a fundamental concept.
That narrative you posted has no ON clauses! And the narrative is also wrong. There is no generic “name”, etc. What tables were used in your non-query? Replace the ?? in this skeleton:
SELECT ??.something_name, ??.sync_name, ??.something_version,
??.ppo, ??.dom
FROM Base_Env AS E, Links AS L, Base_Data AS D
WHERE ?????????;
>> I want to eliminate the duplicate records [sic], can any one help me here?<<
Where is the sample data? Where is the results? Please read a book on RDBMS so you can post correct SQL and try again.

Help with Inner join problem

The following query works fine as long as there is a value in the subID field, which is at the end of the inner join statement. If the subID is blank then no data is output, even though it is there. Try as I may, I can not get the right solution in the where statement to get the data to show without the subID. What am I missing?
<cfquery name="getInfo" datasource="#application.database#">
select page_id, pageName, pages.content, pages.cat_id, pages.seo_title,pages.seo_desc,pages.seo_words,pages.h1_title,pages.pic,pages.brochure,pa ges.video,catagories.catagory,subcat.subID,subcat.sub_category
from (pages INNER JOIN catagories ON pages.cat_id = catagories.cat_id) INNER JOIN subcat ON pages.subID = subcat.subID
where pages.page_id = #page_id#
</cfquery>

Rick,
Looks like you need a LEFT OUTER join to the "subcat" table, so that all records for "pages" and "catagories" are returned even if no matching "subcat" records exist. INNER joins will only return selected records when the tables on both sides of the join statement have matching values, while a LEFT OUTER (sometimes also known simply as a LEFT join) join will return *all* selected records from the table(s) on the left side of the join statement regardless of whether there are matching records from the table on the right side of the join statement. When there are no matching records from the table on the right side of the join statement, any columns in your SELECT clause that are from the table on the right side of the join statement will contain NULLs.
HTH,
-Carl V.

Help with inner join PLEASE IGNORE

Hi I was doing a select with a subquery but I need that the where clause check to values so I couldn't get it so I decided to create a INNER JOIN
Before
insert into BPMTEMP (select * from ODS_VIEWER.BAN_EVENTOS_CONFIRMACION@DBLINK1 where id_solicitud and accion not in (select (id_solicitud, accion) from ODS_VIEWER.BAN_CONFIRMA_RESPUESTA@DBLINK1) and rownum <=200);but the problem with the inner join is that it doesn't accept me the external database source
insert into BPMTEMP (select ODS_VIEWER.BAN_EVENTOS_CONFIRMACION@DBLINK1.*, ODS_VIEWER.BAN_CONFIRMA_RESPUESTA@DBLINK1.*
from ODS_VIEWER.BAN_EVENTOS_CONFIRMACION@DBLINK1
INNER JOIN ODS_VIEWER.BAN_CONFIRMA_RESPUESTA@DBLINK1
ON [email protected]_solicitud = [email protected]_solicitud
ON [email protected] = [email protected]
AND rownum <=200); it shows an:
ORA-02084:
     database name is missing a component
Cause:      supplied database name cannot contain a leading '.', trailing '.' or '@', or two '.' or '@' in a row.
how can I solve this????
thanks for your help

Hi
Please remove the @dblink stuff in the column descrptions or use a table alias. This should help.
drop database link lokal;
create database link lokal
   CONNECT TO whateveruserineed IDENTIFIED BY whateverthing
   USING 'lokal11g';
select HR.COUNTRIES.* from HR.COUNTRIES@lokal;
select x.* from HR.COUNTRIES@lokal x;And as Dan Morgans says, pls. post you ? in the right forum next time :-))

Inner join query

Hi all,
I want to query a inner join via some tools in sap GUI. till now, i could not query a inner join between two tables via SE11. can someone tell are there some other ways to achieve this?
any response will be awarded!
thanks and regards,
samson

hi samson,
Proper use of Inner Join
When multiple SAP tables are logically joined, it is always advisable to use inner join to read the data from them. This certainly reduces the load on the network.
Let us take an example of 2 tables, zairln and zflight. The table zairln has the field airln, which is the airline code and the field lnnam, which is the name of the airline. The table zflight has the field airln, the airline code and other fields which hold the details of the flights that an airline operates.
Since these 2 tables a re logically joined by the airln field, it is advisable to use the inner join.
Select aairln alnnam bfligh bcntry into table int_airdet
example 2:--
Inner join: If you have common fields between 2 or more tables, its betterto use Inner join.
Check the below example:
VBAK & VBAP table has common fields, hence we can use inner join.
SELECT akunnr avbeln anetwr abnddt a~knumv
avkbur aerdat avdatu aaugru
aktext bmatnr barktx bkwmeng b~kzwi6
bvolum bposnr b~kdmat
INTO CORRESPONDING FIELDS OF TABLE g_t_quot
FROM vbak AS a INNER JOIN vbap AS b
ON avbeln = bvbeln
WHERE a~vbeln IN so_vbeln
AND a~trvog ='2'
AND a~vkorg IN so_vkorg
AND a~vtweg IN so_vtweg
AND a~vkbur IN so_vkbur
AND a~audat IN so_audat
AND a~kunnr IN so_kunag.
FOR ALL ENTRIES:
If you get some data into one internal table and if you want to fetch data from other table based on it, use FOR ALL ENTRIES.
g_t_quot is an internal table.
SELECT spras augru bezei FROM tvaut INTO TABLE g_t_tvaut
FOR ALL ENTRIES IN g_t_quot
WHERE augru = g_t_quot-augru AND spras = sy-langu.
From zairln as a inner join zflight as b on aairln = bairln.
In order to restrict the data as per the selection criteria, a where clause can be added to the above inner join.
