Link with derived tables

Hi,
I am trying to solve an issue I am having with reports created with free hand sql in BO 6.1 in BO Xi. I want to create a derived table that will contains the extra data that I need. after I create the derived table, do I need to create all the links from the original tables because I do want that new table to behave like to original ones.
Brian

Freehand SQL , you are making in BO XI as Derived Table, correct??
As I told you, if you want then you can join those to derived tables, no issues. I also did joining tables to Derived tables to work with Inline Views. My queries has Inner join on two tables based on one more inner join with in those.
I used Derived table for Inner INNER join and joined that derived table with other objects.
In Report, you can use both of them same time.
Is it clear or am I missing ??
Thank You!!

The links with VARID table

Dear All,
We have deleted variants in table VARID in order to solve error CKMLRUN112. Error ckmlrun112 in parameters for closing entry definition
But we still get this error in ckmlcp.
Could anyone tell the links with table VARID?
Where we should delete this variants somewhere else too?
With best regards,

With_item linking with fi tables

Hi guys, I am carrying out a requiremnt for Brazil.
I need to print base, rate , tax code and amount all of which have nine types viz inss,ir,pis,confis,csll,iss,funrural,sest,senat.
Now as far as I understand I will have to read bseg with belnr gjahr bukrs and buzei with the same primary keys of with item and then pick up for different tax types. I would like to know is there any way to avoid bseg? can I use bkpf instead ? as my req is for vendor only , but bkpf dosent have buzei. Can anyone explain me the connetion of with_item with fi tables better?
Thanks

BSIK is for Vendor open items, and BSAK for Vendor cleared items.

Stored procedure with database link with "from table(...)"

Hi guys,
I've been told I can't create views on a database by the design team and so have to use this stored procedure to obtain the values.
select HAN_ID, HAN_DS, GLOBAL_IN, LOCAL_IN
from table(cast(ODADMIN.ODP00002_QUERY.Execute001@DBLINK(11312,'EN') as
ODADMIN.ODP00002_001_Array@DBLINK)) WHERE LOCAL_IN = 'Y';I've been told that it works when you remove the database links (so on the actual database) when you remove the cast part. I've tried it with my link and with/without the cast part but it doesn't work. With the example above I get the error: ORA-00907: missing right parenthesis.
When I remove the CAST-AS and the additional parenthesis it brings i get the error: ORA-00904: "ODADMIN"."ODP00002_QUERY"."EXECUTE001": invalid identifier
When I do table( *"* ODADMIN.ODP00002_QUERY.Execute001@MWW_DEV(11312,'EN') *"* )... -- wrapping the call in speech marks I get: ORA-00972: identifier is too long
Anyone see what's wrong? Thanks for any help.

Hi Ben,
Asking now. By a view I mean one local to the database; I could create one on APEX but then I use the database link twice instead of just 1.
His reasoning Ben:
Firstly, Maintenance. We will have to maintain additional views (at additional code). Secondly, if the view has a JOIN, then you can't update through it (without complexities). If we have to get the View to pass the data to a Procedure (that's a pain). Also, standards..
All update occur via either a Procedure, or a Base view, across over 1000 tables
That's the standard, and doing things differently is costly long term
People will not know how it works, it will have to be explained, maintained..etc.
If the Application has the Business Rules, then updates via Base Views, that's a more standard way of developing. Also, if you update via this view, you'll update multiple rows in one call, which is in-effficient if only ONE row needs to change. Therefore, single row updates from the Application is more efficient
The procedure is as follows:
--SET SERVEROUTPUT ON

BI - ABAP To pick the field from One table and link with 2nd table

Hello, I am stuck to write the correct abap code. Requirement is that My Client BMW California require the below:
1. list of invoices (BELNR) that a has tcode = FB01 and FBVB" from Table BKPF. Account Number field (BELNR) is there in 0fiap_4 Data source
2. Now Link the above invoice Number (BELNR) that a has tcode = FB01 and FBVB" from Table BKPF to BMW Custom Table I_BMW_WI. - Field "PAT ID" which is the cocatenation of OBJNR (Object Number), Invoice Number and Purchase Year. where PICK only thos PAT ID where "TYPEID" Value = "BMW" in table I_BMW_WI.
To solve Number 1 Please fix my abap code and help me to write the Code to Solve Number 2 and Link #1 AND #2.
Please help me soon
Code # 1
case I_datasource.
WHEN '0FI_AP_4'.
loop at C_t_data into l_s_DTFIAP_3.
l_tabix = sy-tabix.
clear I_BMW_WI.

endif.
endloop.
endcase
Code # 2 -
Please help with templates.
Thanks
Soniya Kapoor

Hi,
Ad Code #1
First of all the key for BKPF consists of:
BUKRS, BELNR and GJAHR so I think you should use all key fields in your SELECT statement:
select single * from BKPF into I_BKPF
where BUKRS = l_s_DTFIAP_3-BUKRS and
 BELNR = l_s_DTFIAP_3-BELNR and
 GJAHR = l_s_DTFIAP_3-GJAHR.
And why do you test SY-SUBRC after CLEAR ?
Your IF statement should be after SELECT...
And last but not least when you are using SELECT SINGLE you always get only one record so what is the purpose of LOOP statement ?
Try following code:
case I_datasource.
WHEN '0FI_AP_4'.
loop at C_t_data into l_s_DTFIAP_3.
 l_tabix = sy-tabix.
 select single * from BKPF into I_BKPF
 where BUKRS = l_s_DTFIAP_3-BUKRS and
 BELNR = l_s_DTFIAP_3-BELNR and
 GJAHR = l_s_DTFIAP_3-GJAHR.
 if sy-subrc = 0.
 if (I_BKPF-TCODE = FV50) OR
 (I_BKPF-TCODE = FB01).
 I_FINAL-BELNR = I_BKPF-BELNR
 modify I_FINAL.
 endif.
 modify C_t_data from l_s_DTFIAP_3 index l_tabix.
 endif.
endloop.
endcase.

Source(oracle 11g) with oracle 8i using db link with full table scan

Hi,
I'm using oracle 8i version and i'm facing some issue while using DBlinks.
SourceDB1 I'm using oracle 8i(Source)
select * from tab1
tabl where id in
(select id from stab1@SourceDB1 where updt_seq_num > 167720 and work_grp_id in (2900,2901))
For this, I could able to retrive the data.
but, today we have migrated one of our source from oracle 8i to oracle 11G
when I'm executing
select * from tab2
tabl where id in
(select id from stab2@SourceDB2 where updt_seq_num > 167720 and work_grp_id in (2900,2901))
we couldn't able to retrive data as it's scaning full table scan.
when oracle 8i source it's scanning using INDEX scan but if the source oracle 11 h it's scanning full table scan.
Could you please advise how to resolve this issue for source oracle 11i ?
Please let us know, if you need any information.

Blocks that are read via full table scans are stored in the buffer cache, but putting them at the MRU end ensures that they don't push the rest of the useful blocks out of the buffer cache. In your example, if you're full scanning a 2 GB table (T) with a 500 MB buffer cache, the first block that is read from T is put at the MRU end of the buffer cache, displacing the previous block that was at the MRU end of the cache. The next block that is read from T is also put at the MRU end of the buffer cache, displacing the previous block that was at the MRU end of the cache, so block #2 from T displaces block #1 from T. So, you're reading 2 GB of data, but you're constantly purging the older blocks, so you're only really using that last block of the buffer cache.

Find the idoc segment link with Sap Table

Dear Abaers,
I am new to Idoc. i have one Idoc (Orders01) for creating sales order.
I had seen the t-codes WE 30 and WE 60 to know the field description.
The fielddescription shows names like name1 name2 ort01 etc.
i want to know what are the db tables involved for that particular idoc segment.
Thanks in Advance,
Arati

Hi Arati,
to get the description name:
WE30 transaction and check the segments name available.
With the segment name, go to WE31 and check the fields used and column 'Data element'.
Double-click in data element (or inform in se11), you have the description value of the field.
About the tables involved:
Click in 'Where use list' os this data element.

To find the tables which is having link with particular table.

My task is to delete the data in the job_header table.
Before doing this task, i want to know which are the tables referencing this particular table.
in other words i have to delelete child records first then i have to delete the above said table.
is there any way to know the child table existance for this particular parent table?
Thanks..

Linking Tables & Derived Tables.

Hi,
I am having a problem performing an inner join on a standard table and a derived table. I have been trying syntax along the lines of :
select test.person_id from person inner join (select person_id from person where person_id = 1000) Test on person.person_id = Test.person_id
This is obviously a simplified (and useless) example of what I am trying to achieve . I keep getting an 00933 error Sql command not properly ended.
I am trying to transfer logic from SQL Server where the above syntax would work.
Any help greatly appreciated.
Dave

Thanks Tony, you're right.
I was using Oracle 8. Having now checked on an Oracle 9 system I get the desired result. Do you know of any way round the issue?
The problem in a little more detail: I have a Person, an Address and a Person_Address table. In the Person_Address table there are numerous addresses associated with the person. There is a START_DATE field for each record.
By creating a derived table, as below, I can identify the latest address associated with a person and then by linking this derived table with the Person and Address table complete the required query. Without the derived table I am a little confused.
SELECT PERSON_ID, MAX(ADDRESS_START_DATE) AS ADDRESS_START_DATE
FROM PUPIL_ADDRESS
GROUP BY PERSON_ID
Any Ideas?

@aggregate aware or Derived Tables ..

Hello,
the original data in my Universe has about 2 Mio. i have 2 questions ..
is there any reference values for best performance of a universe (e.g 1. Mio rows .. what ever)
how can i get best performance: @aggregate aware or with derived tables .. (other Alternatives)
Production DB: Oracle
BOXIR2 SP 4

Hi,
You can get better performance with aggregate awareness, but you need the aggregate tables in the db.
As a brief overview consider a table prod_cust_order (1million rows)
Product, Customer, Order Amount
This could be aggregated to product_order Product, Order Amount (500 rows)
If the user wants to see order amount by customer then they are going to have to query the original table, but if they are interested in product only they they can go to Product_order table.
The aggegrate awareness allows you to create a measure object with both tables as the source, and will then select the approriate one when building the query based on the dimension you have selected. So if the user selects customer then it will go to the top prod_cust_order but if they don't it will source it from the much smaller Product_order table. The user does not see the change in WebI unless they look at the underlying SQL.
Derived tables are not so good for performance as the enter derived query is included in the SQL built.

Alan

Slow Query over Database Link with Bind Variable

I have a query over a DB link, with all tables on the remote database.
If I use a bind variable (from Toad), the query takes 4 minutes. If I replace the bind variable with a constant or substitution variable, it takes 1 second.
The query runs fine when run directly on the remote database using bind variable.
9.2.0.7

Look up "Bind variable peeking"
What's happened is you have an execution plan that differs from the one with the constant. Why? My bet is that Oracle "peeked" at the bind variable to help it decide which execution plan to build. It then cached it. It probably cached an execution with an index when it should be doing a full table scan or a hash join instead of a nested loop. It's hard to say specifically what it is.
Try this, flush your shared pool and rerun the query with the bind and let us know if it takes 1 second or 4 minutes. If it takes 1 second, then that was probably it.
Read part 2 of Tom Kyte's blog post on what it is and it's behavior.

Can I Select from table skipping extents linked with lost datafiles?

Hi~,
I need your help to recover my database.
I'm using oracle 9.2.0.8 at Fedora 3 with no-archive mode.
and I don't have any backup.
Last night, I experenced hard disk failure.
I tried OS-level recovery, but I lost some datafiles of tablespace.
anyway, I wanted to recover my database without data of lost datafiles.
so, I issued "alter database datafile offline drop" and
start oracle instance.
But, datafiles were not removed from dba_data_files view and
extents linked with lost datafiles were not removed from dba_extents view!
Selecting query of some table containing extents linked with lost data files,
I got "ORA-00376: file xxx cannot be read at this time" message.
So, my question is that..
HOW CAN I SELECT FROM THAT TABLE WITHOUT SCANNING EXTENTS LINKED WITH LOST DATA FILES?
Thanks.

Hi,
Without being in archivelog and without backup, one can't do any sort of recovery. That's why backups and archivelog are so so important.
The offline data file command never does actually drop the datafile. It merely indicates to the control file that now the said tablespace will also be dropped. This won't update any view that the files are not supposed to be used or shown to you anymore.
This is what documentation says about the recovery of the database in the NoARch mode,
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14191/osrecov.htm#i1007937
You do need a backup in order to get those tables being read. Oracle doesn't have any feature which can offline/skip the missing extents for you and let you read the data without them.
HTH
