Ouer join in RPD
Hi Gurus/Experts
I want to apply an outer join on a fact and dimension table. I am very new to OBI and have no idea of how to go about it. i had read a few links which says creating an opaque view etc but have not got a clear picture.
Quick response would be really appreciated.
Hi,
If you want to give the outer join with the fact and the dimension. Then give the join condition in the physical layer.
In the BMM layer, open the fact table general tab and you can find symbol to add new tables. It will list all the tables with which the fact table is joined in the physical layer. Then add the dimension table and in the'joins' section you can find the dimension and the fact table with a 'tick' symbol and inner join as default. You can apply outer joins(left,right,full) depending upon your requirements.
You need to create a opaque view when you need to retrieve data from dimension and dimension. In order to provide BI server one fact table common to both the dimensions. But if you have fact and dimensions already for you coming from the database, then its not required.
Hope this clears your doubts.

Hi All,
I want to document all Physical Joins present in RPD. Is there any way to do it instead of going through each and every join and documenting manually.
Thanks1.) Agreed.
2.) Not really. This is a physcial FKey in UDML:
DECLARE FOREIGN KEY "Writeback (MSSQL)".."PADISHA"."Writeback (Fact)"."Writeback (Fact)_FKey" AS "Writeback (Fact)_FKey" HAVING
"Writeback (MSSQL)".."PADISHA"."Writeback (Fact)"."COMMENT_ID" ) REFERENCES "Writeback (MSSQL)".."PADISHA"."Dim - Market (WRITEBACK_F)"."COMMENT_ID"
PRIVILEGES ( READ);Join expression:
"Writeback (MSSQL)".."PADISHA"."Writeback (Fact)"."COMMENT_ID" ) REFERENCES "Writeback (MSSQL)".."PADISHA"."Dim - Market (WRITEBACK_F)"."COMMENT_ID"Tables:
- "Writeback (MSSQL)".."PADISHA"."Writeback (Fact)"
- "Writeback (MSSQL)".."PADISHA"."Dim - Market (WRITEBACK_F)"
These tables are alias objects and point to the physical table.
So UDML has all you need. -
Complex Join in RPD with Subquery
Hi Experts,
We have a complex requirement in our RPD Development which needs to use a subquery in the complex join in Physical layer. Here are the tables:
Fact A
DIM B
Join is A.case_no = B.case_no
and ( a.active_date between b.start_date and b.end_date or
(a.active_date < b.start_date and
b.start_date = (select min(b2.start_date)
from DIM B2
where b.case_no = b2.case_no
group by b2.case_no
Is there a way other than creating opaque view or making ETL changes to having the min(start_date) as part of the table ?
Appreciate your inputs and responses.
Thanks
VKyou got 2 tables or 3?
I see 3 tables A, B and B2
you need to join B with B2 time being just ignore min value since its equi join you get matching only
and then B with A
in bmm map B2 to B -

Hi, I know that we create foreign key joins in the Physical Layer and complex joins in BMM layer. Can we create complex join in Physical Layer and foreign key joins in BMM layer? Under which circumstances should we do this? Is there any benefit/disadvantage in doing so?

Hi,
I got a requirement to design Infoset with OUTER JOIN between 2 ODS. Even after making the outer join query is displaying the output as INNER JOIN.
Contract ODS (0CRM_CNT2) [T00001]
Contract Number
Contract Item
Sales ODS (ZCRG_O16) [T00002]
Contract Number
Contract Item
Above 2 ODS are joined by Contract Number and Contract Item and marked Sales ODS as LEFT OUTER JOIN. I want to list all Contract line items in the query output even though there is no sales on that contract item.
SQL from the Query
CREATE VIEW [/BI0/0300094697] AS
SELECT
[T00002].[FISCVARNT] AS [K____1321],
[T00002].[FISCPER] AS [K____1322],

Unable to do Physical Join in rpd
Hi
I tried to join table Ra_Customer_trx_all and OE_order_header_all but the join condition is to_char(OE_order_header_all .order_number) = Ra_Customer_trx_all .Attribute6
can i use this join condition in physical layer..Because in physical join we staraightway give the join condition but here we are changing the column type and then using the join.
I am using OBIEE 11g
thanks in advance for the help

Bug in either ANSI Join or Oracle 10.2
I can't tell whose bug this is, but it's almost certainly a bug.
My co-worker Martin wrote a query (below) that returned zero rows, which he knew was wrong.
In exploring this further, he discovered that rewriting the join from ANSI 92 to the old WHERE clause join suddenly caused a "ORA-00918: column ambiguously defined" error to arise.
Then, when he added a table qualifier to one of the column names (effective_dt became fam.effective_dt), suddenly he began to get his data.
So, here's my question. Why does a query that uses ANSI-92 Join syntax not raise the "ORA-00918: column ambiguously defined" error, WHEN THERE WAS AN AMBIGUOUSLY DEFINED COLUMN? Does the ANSI-92 join syntax imply some sort of hierarchy of table precedence that resolves the ambiguity by implication?
Here's the query, FYI:
SELECT fam.asset_mix_percent_nbr

JOIN rp_mip_rpd_fund mrf ON fam.rp_mip_rpd_fund_seq =

Joining bridge ,dim,fact table
Hi
I have scenario where I have a bridge table,dimension table,and 2 fact tables.
The dimension table is a common table for both fact tables.
The bridge table contains the dimension tables Primary key.
The bridge is also having an other dimension table PK, but that table is not joined to any fact table.
Now I have a req where I have to get a column from bridge table and fact2 tables.
Individually when I pull those columns I am getting data.
When I pull those 2 columns together , getting " the specified criteria dint result in any data".
Tried changing joins in RPD nothing worked.please help me , this is very urgent.
In SQL developer when I joined bridge and fact or dimension and bridge I am able to get expected results.
Thanks

Outer join style report - OBIEE 10g
Hi All,
I have a requirement to generate a report for product & sales. I have two dimensions and various fact data elements.
Some products may not be sold on a month but still i want to display them in the report with 0 value. I have tried this by creating a Left outer join in RPD, since we are using some other dimension in the fact calculation (calculated column) so that also comes in to the left outer join group and that mess with the results.
So am looking for the better approach to bring the results through answers. Here is the data and expected results
Data
Product | Month | Sale | Margin
Fridge | May | 100 | 20%
Coolers| May | 50 | 4%
Laptop| Jun| 300 | 15%
Now am filtering the report for the month of May, my results should be looks like
Product | Sale | Margin
Fridge | 100 | 20%
Coolers|50 | 4%
Laptop| 0 | 0%
Can anyone provide a solution for this ?
Thanks,
UgserOne possible solution is based on the fact, that OBIEE is combining (=outer joining) measures from two different fact tables by their commonly shared dimensions. What you have to do is:
Physical layer:
- create a new dummy fact table in the physical layer (e.g. using a view like Select 1 from dual;)
- join all required dimension tables to the dummiy fact table using a complex foreign key. Make sure it evaluates always to true, e.g. 1=1.
BMM:
- create a new logical fact table for the dummy fact and join all required logical dimension tables to it using complex joins. Set the levels in content tab of LTS same way as for your other fact.
Presentation layer:
- expose the dummy fact column
Answers:
- Drag the dummy fact into your report. You might want to hide it because for a normal user it is confusing and meaningless since it will always show 1.
- Filtering should work fine now.
The dummy fact column will cause OBIEE to create a cartesian join, i.e. all combinations of dimension attributes used in the report will be created. Then the result of the second fact (in your case sales) will be added. In your example it will create a record for each Month for each Product. Sales and Margin will be only added for those Month and Product combinations where there are data in the sales fact.
Hope this helps.
Cheers,

Hi All,
I am creating reports from two fact tables. However, in spite of using only inner joins in RPD, obiee is generating full outer joins between two WITH (sub-query factoring) . Is there a way to enforce inner joins.

i have doubt on ouer joins.
may i know the difference between query one and two.
1)
select count(test1.EMPNO)
from test1,
test2
where test1.empno = test2.empno(+)
AND test2.dept(+) = 'SALES'
2)
select count(test1.EMPNO)
from test1,
test2
where test1.empno = test2.empno(+)
AND test2.dept = 'SALES'In the first query outer join to test2 ( unmatched records from test2) also appears. so nulls ( additional rows) from test2 will come even there no matched department with 'Sales'..
In second. Even outer join happened to test2, there are only rows with sales department will appear.. no additinal rows can be seen -
Default Selection Issue in Dashboard Prompt
Hi All,
I am using the below logical SQL in SQL Results for Default Selection of a column in a dashboard prompt,
SELECT "Facts"."Service Provider", "Config"."Integration Id" FROM "IMONIT - Transaction Log" WHERE "Config"."Integration Id"='@{inttype}'
Here, I have used a presentation variable, which is set by another prompt. Also the Facts and Config table are joined in RPD. The issue is it does not selects the values returned by the logical SQL by default. But if i use the same logical SQL in SQL Results of Choice List Values for the same column in the prompt, the logical SQL does work and populates the prompt only with the values returned by the logical SQL.
Any help is much appreciated.
Regards,
MariaDeepak, actually the scenario is that I am navigating to the page with the dashboard prompt from another answers report located on another dashboard page. This SQL works perfectly when I press the GO button of prompt on the same page. But its not working when I am navigating to the same page with the prompt from any other report. Any ideas ?

Hi All,
I apologize to bring similar question. .
I am able to create the logical foreign key for logical table A with new joining condition (A.2=B.2) (2 is calculated logical column).
However there still exist Physical foreign key join with old condition (A1.=B.1). When I deploy this rpd, the report generates sql with (A1.=B.1) join condition.
Then,I removed this Physical foreign key join in rpd,and got a warning' logical dimension B has a source that does not join with any fact table' in consistency check.
Still after deploying this rpd , I am getting error [nQSError: 14025] No fact table exists at the requested level of detail: in report.
I am missing anything.The logical foreign key has correct join condition still it is not over riding the physical join.
Thanks for going through this question,
http://tinypic.com/r/2qiwmrr/6Based on your comments I'm looking at documentation:
I found a Note: A logical key for a fact table must be made up of the key columns that join to the attribute tables. Logical foreign key joins may be needed if the Oracle BI Server is to be used as an ODBC data source for certain third-party query and reporting tools.
I need to see why ODBC, and unlike the Logical Foreign key join is not overriding join Physical layer.
Btw: Since you want to go with a join using defined logical column, can you use the same expression in Physical join using expression builder?
This should work.
EX: T43770.DEPARTMENT_ID = case when T43764.DEPARTMENT_ID > 10 then T43764.DEPARTMENT_ID else 0 end
