Physical layer design in obiee 11g

Hi,
I need a clarification regarding physical layer degin in obiee 11g,I imported Oracle Apps reports ,but could not find any keys there at table level.So should i create keys on the imported table level or at the alias level of the imported tables.
Thanks-Bhaskar

If you import a transaction table you may have keys imported in physical layer but when you going with warehouse table you may not have keys at database level, you define them using join in physical layer.
We have surrogate keys in dwh.
Hope this clear your doubt, if helps pls mark

Re: View physical query issued by Obiee 11g

Guys,
I want to view the physical query generated by the report in OBIEE 11g, but in the logs, i can only see these queries: (Just writing the first line to illustrate)
SELECT
0 s_0,
"Marketing Contact List"."- Account Address"."Billing Abode Name" s_1,
And this query:
RqList distinct
0 as c1 GB,
Account.Billing Abode Name as c2 GB,
Both these queries are NOT the physical ones.
I have the appropriate log level, and even set it manually from the front end, but I'm unable to view the physical query. Please help!

A.Budd,
After running a report in OBIEE, click the Administration Link in the top right corner. New window appears and select "Manage Sessions". Look for the latest time executed that applies to the time you executed your report and click View Logs. Scroll almost to the bottom of the log.
What you are looking for is the generated logic that starts with "*With*"
WITH
SAWITH0 AS (select sum(T443244.AGING030) as c1,
sum(T443244.AGING6190) as c2,
sum(case when T443244.CURRENCYCODE = 'C
Copy the whole logic from WITH to the end of the logic (typically ends with Order By) (not the log) and paste it in your query tool. This is based on the physical layer.

OBIEE | Using Dynamic Session Variable in Physical Layer

Hi All,
Any idea if we can use Dynamic Session Variables (I think they are also called Repository Variables) in our physical layer. I basically need to set the value of this variable from dashboard when a link is clicked, and then use this in my SELECT query at physical layer so that OBIEE does not pull all the data from the database tables.

Christian,
Thanks for the quick response, ok we have actually moved to a different solution now, we are actually using Direct Database Request because one of our reports is supposed to be accessing direct transactional system i.e. for this report we are using OBIEE as a reporting tool. We are able to do that and even create links between different reports i.e. based on prompt in Report A filter Report B, but the scenario now is that we need to set a presentation variable from Report A when a navigation link gets clicked, because so far according to our knowledge direct SQL only allows presentation variables in its WHERE clause. So, any ideas how can we set a presentation variable when a navigation link is clicked. Thanks.

Snowflake design in OBIEE

Hi All.
I have a query here w.r.t snowflake dim in OBIEE
I have a Fact table and 3 dimension tables
The joins are something like this
DimB --> Fact A
Dim C --> Fact A
Dim D -->Dim B
here Dim B is snowflake to Dim D
In physical layer we have joins this way
In BMM layer we have all the 4 tables and have complex joins from DIMB to FactA and DimC to FactA and DimD to Dim B.
We have a hierarchy on Dim D
And mapped to lowest level of Dim D hierarchy to Fact A, it shows me a message "Logical dimension table TABLE X has a source TABLE X that does not join to any fact source" error..
Can anybody help me resolve this pls.
Thanks in advance...

Hi,
I have similar requirement.
My Physical layer design is like-
DimC --> Fact A
Dim D --> Fact B
Dim E -->Dim C
Dim E -->Dim D
Dim E is not join to any fact in physical layer. Dim E is joining always through DimC or DimD to fact tables. I have created 2 aliases for DimE to join to 2 different dimensions in physical layer.
How to design the BMM for Dim E
I have separate logical tables for DimC and DimD
Thanks in advance

How to Hide a column in OBIEE 11g

Hi,
I am trying to hide a column of presantation layer table in OBIEE 11g. But it is not working.
I am doing the follwoing.
Open the permission tab of the column.
Given no access to Everyone.
Given No access the user/Application Role.
When i go to web, the column is getting displayed in the table list. But, when i select the column and press the result button, it is not giving the result.
It means, by doing the above steps it is restricting the data but visibility of column is already there.
Same way it works for OBIEE 10g. Could you please let me know this feature has been removed from 11g or if it is still there then how we can achieved that.
Thanks in Advance
Niraj

Hi Niraj,
It's a bug in OBIEE 11.1.1.5.
Bug 12352010: RESTRICTED COLUMNS SHOULD NOT SHOW IN SUBJECT AREA
It is fixed in the version 11.1.1.6.

Fact columns Datatype is changing from char to int in OBIEE 11g

Hi ,
I am taking measure columns - "product description","tot cost" against a dimension "project name" .
I am generating this report in a planing form and OBIEE .
in planing form :
product description tot cost
project name
P1 A 1500
p2 B 1700
p3 C 1800
in obiee report :
product description
project name
P1 16 1500
p2 17 1700
p3 19 1800
Somehow , measure's datatype are getting changed from char to number , in OBIEE report.
By default , the data type for all fact's is Double .I tried changing that to varchar , but result is same .
Do I need to change anything in physical layer / RPD .
OBIEE version : 11.1.1.6
Essbase version : 11.1.2

Hi ,
Thanks for your reply . To confirm , the data type of product description column is "double" in essbase .
I found out ,thers's a RDBMS table , consisting of two columns - ID, text value . where product description's are in text value's with the corresponding ID's(integer values) .
Now , when I am creating a form in planning , its fetching the text values of product description (there's some inbulit setting's available for this in plannng) .
However , in obiee its fetching the ID values of product description .
So ,
1. Is there any similer setting I can do for OBIEE , so that it's fetches only text value's of product description .
2. If not , then I have to join the essbase fact table with this RDBMS table . I am not sure how to do it .

Diffence between physical layer and BMM layer

Hi all,
Please let me know the difference between Physical layer design and BMM layer design. Please write your views in your reply instead of links.

Use in the layers
The physical layer is the layer of the Logical Business Model where you define the physical data model of your data source. It contains information about the physical data sources.
The most common way to create the schema in the Physical layer is by importing metadata (table, view, …) from databases and other data sources. If you import metadata, many of the properties are configured automatically based on the information gathered during the import process. You can also define other attributes of the physical data source, such as join relationships, that might not exist in the data source metadata.
In the Business Model
In the business model, OBI recommends using complex logical joins instead of foreign key logical joins.
When Complex joins are used in the business layer then they are really acting as placeholders. They allow the OBI Server to decide on which are the best joins define in the Physical Layer to satisfy the request.
In a Dimension, you may have multiple Logical Table sources that all join to one fact table. The OBI Server will then decide the best joins to use to meet the requirements.

Sum Aggregation Error in Physical & BMM Layer in OBIEE 11g with Essbase 11

Hi everyone,
I'm using OBIEE 11g with Essbase 11 as the data source. I'm using Sample Basic database from the Essbase as my data source. If I'm using the hierarchy for the measures (so I don't flatten the measures), and when I changed the aggregation in both physical and BMM layer from Aggregate_External to Sum, I can't create a report at all from the Answers.
Does anyone encounter the same thing? Any ideas/solution about this? Please help.
Thanks a lot!

Hi Deepak,
When I picked the "Basic - measure" alone, I got this error.
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 43119] Query Failed: [nQSError: 96002] Essbase Error: Unknown Member Basic - measure used in query (HY000)
SQL Issued: SELECT 0 s_0, "Sample Basic"."Basic"."Basic - measure" s_1 FROM "Sample Basic".
When I picked the "Gen1,Measures" alone from the measure dimension, I got this error:
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS.

SQL Issued: SELECT 0 s_0, "Sample Basic"."Measures"."Gen1,Measures" s_1, SORTKEY("Sample Basic"."Measures"."Gen1,Measures") s_2 FROM "Sample Basic"
But when I queried the dimensions one by one (only single dimension each), no error was shown.
This only happens if I use Sum in the physical and BMM layer. If I use External_Aggregation, these errors do not happen. And if I flatten the measures, these errors also do not happen.

Not able to update row count in Physical Layer..connection failed in OBIEE 11g

Hi Guys,
I am not able to do Update Row count in the Physical Layer, i am getting an error The Connection has failed. This is in OBIEE 11g Linux env.
I have put the tnsnames.ora file in the below path:
/*****/pkgs/linux/intel/OBIEE_DIT/MW_HOME/Oracle_BI1/network/admin/
I do not have admin under
/****/pkgs/linux/intel/OBIEE_DIT/MW_HOME/oracle_common/network/
But if i put the whole TNS entry in the Data Source Name i am able to connect:
(DESCRIPTION =(ADDRESS = (PROTOCOL= TCP) (HOST= xxx.xxx.com) (PORT= 1671))(CONNECT_DATA = (SERVICE_NAME = US1OBIEE)))
I am not able to understand the issue..
Thanks,

Looks like rpd is looking for local tns config... try to use as hostname:port/ServiceName
This should work, just in case not working! stop doing so since it is know issue.

How to use BETWEEN Operator in physical layer in OBIEE 11g

Hi Experts,
How do I do the BETWEEN Operator functionality in Physical layer if my requirements is like this?
TABLE_1.COLUMN_1 = TABLE_2 is between COLUMN_2 and COLUMN_3
Below is the syntax for BETWEEN Operator function when I am trying to insert them.
<<expression>> BETWEEN <<Upper Bound>> AND <<Lower Bound>>
Thanks,

Below is an example diagram, as you can see, FACT TABLE have a join (an arrow one) towards TABLE_1 and TABLE_3. AS for the TABLE_3, this table is the one which I implement with the BETWEEN Operators function in Physical Layer. Also, the arrow in FACT TABLE and TABLE_3 is a red one with no arrow head line.
TABLE_2

FACT TABLE ---------> TABLE_1

OBIEE 11g - complex join in physical layer

Hi, I need to create a complex join in the physical layer with join criteria like the following:
fact.fiscal_year = dim.fiscal_year and fact.accounting_period <= dim.accounting_period
Every time I try to do this, I get the nQSError: 37005 Transaction Update Failed message. Any ideas what is going on?
Thanks,
Scott

Actually, I (finally) got it to work - wow logical joins are a big pain in the butt in 11g. First off, I had to edit the RPD offline, couldn't get it to work (at all) online.
Next I had to delete the existing joins...there appears to be no way to change an existing FK join into a logical join.
Next created the logical joins as stated in my original post - but had to fiddle with it for about 15 minutes to get it to work. You can NOT click the two columns on the dim side, two columns on the fact side, and then just edit the default formula (which defaults to have = sign between the expressions) - because it creates a FK join, and then you start getting errors. Instead, I had to build the expression from scratch.
All in all, 11g has gotten much less flexible and easy to use in this regard.

OBIEE 11g: Physical Layer acting as level of abstraction against ddl change

Does anyone know of a way to insulate the RPD physical layer from DDL changes on the database. So, for instance a column name changes. Currently we use physical views (PVs) to provide a layer of abstraction but want to see if there is another solution. If the database team changes the name of a column, we want it to be seemless and not require changes within the RPD. There is the physical update in the utility box but this is manual so would not be a solution unless it could be automated. Any ideas on how to handle would be appreciated.
Thanks,

I don't think so there is any utility which captures the column name changes as such.
However you can do these things if your modelling comprises of views or Mviews.
You can ask your DBA to change the actual table column names but not Mviews or Views name.
In your view query you always use alias for each of the column in that way you can retain view columns even if base table column changes.
How ever you should change your view as and when your column name changes..
Please mark helpful or correct if it answers your question.

Creating views in Physical Layer of OBIEE Administration Tool

Hello,
I am doing a proof of concept of creating an OBIEE repository using the Administration Tool to make a model for an in house sandbox OLTP system. Because this POC isn't using a warehouse that is built nicely with everything I need, I am having to import the OLTP tables into the Physical Layer and then create a few extra views (by creating a new physical table object and selecting "Table Type: Select") to add some new columns I will need.
My problem is that once I have created two views 'ViewA' and 'ViewB', I want to then create a third view 'ViewC' that is the union of 'ViewA' and 'ViewB'. But when I create ViewC from these two views and try to then update row count or view data in newly created ViewC, I get an error message of the effect:
Message 208: Invalid object name 'DBO.ViewA'
Message 208: Invalid object name 'DBO.ViewB'
When I try and create ViewC with DBO.OriginalTableA and DBO.OriginalTableB, however, it works just fine. And I am also able to successfully update row count and view data in ViewA and ViewB independently. So it seems to me like a view initialization problem when trying to have ViewC be created from A and B.
Am I trying to do something that is not allowed in the Physical Layer of the BI Admin Tool? I would think that I should be able to work with views just like actual physical tables from my OLTP. Maybe not.
Any help or insight would be greatly appreciated. Many thanks.

Hi Hammett81 ,
I think, I have given configured connection pool correct. (following Oracle guidelines: 'In the Connection Pool dialog box, on the General tab, verify that the call interface is set to Default (OCI 10g) and change the data source name to the appropriate tnsnames.ora entry ( ORCL in this example). Please note that this is the TNS service name, not the ODBC DSN. ' )
I tried to give ODBC DSN (SH) as call interface, which resulted in an Error dialogue, implying, previous configuration was correct.
So, I reverted back.

Physical Query in OBIEE 10g vs OBIEE 11g

Hi Everyone,
We're in the middle of an OBIEE 10g to an OBIEE 11.1.1.6.4 upgrade and as part of our assembly testing we were planning on comparing the physical query generated for a report generated in obiee 10g vs the physical query for a report in obiee 11g.
After a couple reports we noticed that the query structure in 11g is completely different than the query structure in 10g. The reports still generated the same data in 10g vs 11g. So my question is:
1) is it worth while (or necessary) to do a physical query comparison for an obiee 10g to 11g upgrade? or is validating the front-end report data & drill down/interactions adequate?
2) what are some general reasons why a query generates differently in obiee 10g vs 11g?

Pl post details of OS versions, exact database versions (to 4 digits) and init.ora parameters of the 10g and 11g databases. Have statistics been gathered after the upgrade ?

Selecting data source in physical view in OBIEE 11G when using sql server

Hi,
I doing my physical view against a 2008 R2 SQL Server. Looks like the list goes upto 2005. Should I select 2005 in that case? As per image: http://i.imgur.com/3H7MO.png
Cheers.
I am using OBIEE 11G 32bit Windows.

Hi,
Yes can. either you can select as SQL 2005 or ODBC basic also can
I hope your version less than obiee11.1.1.5.0, version 11.1.1.1.6.0 and above has update SQL 2008 in the data source selection list.
