Samplesales.rpd - Understanding the physical layer

Hi,
I am trying to create rolling 3 months sum and am going through the samplesales.rpd to get an idea.
I am not able to follow the reason behind the creation of physical alias table A20 Dim Rolling Time Mth.
It has an equi join with the time dimension A08 Time Mth.
My question is, can't we directly join time dimesnion (A08 Time Mth) with A21 Fact Rolling Time Mth.
Thanks in Advance.
Anand

Dont think there is an option to import comments directly, nqudmlgen / XMLAPI approach is the best way. repeatable process may help to update description periodically
hope this helps..

How to see the tables which are in the physical layer of SampleAppLite rpd

Hi Everyone,
I am new to OBIEE and I installed OBI Apps with Oracle 11g in my laptop. I tried to create reports using the OracleBIAnalyticsApps rpd. How can I know from which schema the tables are coming in the physical layer of the repository so that I can create a connection pool to the database. I got the default SampleAppLite rpd when I install the OBIEE but I am unable to see those tables in the database schema which are used in the SampleAppLite physical layer. Can anyone tell me how can I see the tables in the database which I see in the rpd. Actually my question may be wrong as I am new to this field, so please let me know if this is a wrong question. As I unable to express my question correctly. Thanks.

For the OracleBIAnalyticsApps rpd - the tables are under "Catalog" then "dbo" in database "Oracle Data Warehouse" in the physical layer. The RPD comes out of the box with the required connection pools - you dont need to create any. The connection pools "Oracle Data Warehouse Repository Initblocks Connection Pool" and "Oracle Data Warehouse Connection Pool" in "Oracle Data Warehouse" read the data from the business analytics warehouse that you created in a schema name of your choosing with the DAC. All you need to do is edit the user name and password and the data source name with a connect string - which is the local net service name to your database for default call interface OCI 10g/11g assuming you used an Oracle database for your warehouse. One way to test the connection pool is to right click any table/alias then "Update Row Count".
BTW Using the Admin Tool open the OracleBIAnalyticsApps rpd then do "Tools" then "Utilities" then "Repository Documentation" then "Execute". This will create a spreadsheet showing you all the mappings from the presentation to business to physical layers.

Defining Keys/Joins in the physical layer

When the keys and the join conditions are defined manually using a table's Properties dialog box in the Physical layer, do these keys or joins also get defined in the database automatically? My understanding is that it does not get created in the database. So what I am trying to understand is - once the joins are defined in the RPD physical layer, do I have to then define the indexes/constraints in the database as well?
Thanks,

Not required. Indexes can be created in DB on joining col for performance purpose only.
Hope this helps

OBIEE RPD Descriptions in Physical Layer

Is there anyway to auto-populate the Descriptions in the Physical Layer of the RPD. For example. all the Physical Tables and Columns allow for Descriptions. We'd like to keep these descriptions synced with what we have in our DB/ETL platforms. I don't think you could use variables with this option but didn't know of any way that may allow us to automatically push the descriptions into the RPD.
The Presentation Layer has the Externalize Strings which is a great option on that side, however, anyone know of an applicable feature for the Physical Layer object descriptions?

Duplicate table and Alias table in the physical layer

Hi,
I want a clear information regarding the duplicate tables in the physical layer of the rpd.
I mean what is the purpose of the duplicate tables in the physical layer.........
thanks,
chinna.

what do you mean by duplicate of physical table? is it Alias table?
if then,
-> aliases are created to break the circular joins (which are not supported by obiee)
-> and, as per apps standards no operation can be done on base tables which are imported directly to physical layer. Only aliases are joined and will be used in BMM layer
-> useful to re-use the table more than one time , best example: W_DAY_D in apps rpd

Combining multiple databases into one in the physical layer

I have several databases in the physical layer that I would like to combine into one database. How can I do this safely without interfering with the existing physical joins in the physical layer and the column mappings in the BMM layer ?
Can you recommend the best procedures to follow in order to get this accomplished?
Boniface Ntawutarama

hi Boniface,
I think so No,you cant combine all databases into single one.Actually why you want to do this?
According to the requirement you select a database and concerned tables to build the repository,same way with other databases also you build RPD and establish joins in physical layer
Lets wait for any more specific answers on this from experts.

Refreshing the Physical Layer ( New Columns)?

Hi,
I am new to OBIEE. (11.1.1.5)
I have a physical layer defined and now I have added some additional columns to these tables in the database.
Now, How to get these new columns reflected in the Physical layer.
I tried the Tools -> Utilities -> Update Physical Layer.
But it only checks for the data types of the existing columns already in the Physical layer.
Please help.

Use File->Import Metadata option
The tables and column which are in RPD are grayed out and which are not available are in black.
Pls mark correct or helpful if helps

Joins in the physical layer

Hi,
I have a small doubt:
Is it possible to to give the Outer joins in the physical layer+ of the RPD.i.e.,left outer join,right outer join and full outer join.
If yes can you pls provide me any links related to that.
Thanks,
Chinna

Hi,
No we cannot have outer joins in Physicla layer.
We can outer joins in BMM layer.
In BMM layer - complex join can be full inner join or full outer join or whatever your criteria was,but in physical layer - physical join is always an inner join.

Issue while writing a query in table type select.in the physical layer

Hi gurus,
I am actually trying to create a table using select in the physical layer..... i acutally am not aware what it is called but its when i click a table in the physical layer i have an option table type and i chose select which allows me type my query..the query is
Select
coln name(which is a lengthly list of conversion) AS column_name
From Table name.
when i view the data rom the physical layer everthing seems to be fine. but when i try to view the data in the frnt end it gives me an error maximum length is too long than 128....
i am aware of this issue the sql server allows only column of length 128..but none of my column length is greater than 128..
Could you please help me in this
Many thanks in advance

hi veeravalli ,
Thanks for the reply....actually the corresponding reports for this have already been prepared...i created a view in the backend with the same select which i wrote before and and tried calling the view from her.. i have viewed the data and all is perfect...but when i try viewing it from the front end it error saying invaild object name select * from databasename.dbo.View_name...but i have checked the view exists in the backend...
Thanks in advance....

Creating filtered view on the physical layer ussing session variable USER

Hi:
I´m creating a view on the physical layer, the view needs to be created dynamically. So depending on the user (using the session variable USER) the view is created with the data a particular user is able to see.
Fisrt I imported the table and changed it´s properties to be created through a "Select Statement" so i don´t needed to change the mapping on the bussiness model layer.
The consistency check was OK but i´m not able to see data in answers, even using the Administrator user. Have anyone tried to do this? Here is my query.
Thanks
A Garcia
Select * from D_ESTRUCTURA_RH2 where Region_ID
IN
select distinct a.REGION_ID from APP_INDPERSONAL_DM.D_ESTRUCTURA_RH2 a
inner join (
select distinct b.REGION_ID from APP_INDPERSONAL_DM.D_ESTRUCTURA_RH2 b
where exists (select 1 from APP_INDPERSONAL_DM.Autorizacion a, usuarios c
where a.app_id = 1
and a.usuario_id = c.Usuario_Id
and UPPER(c.Nombre_Usuario)=UPPER(':USER')
and a.miembro_id = 'REGION_ID'
and a.operador = '='
and (b.REGION_ID = (case when valor = 'Todo' then 0 else valor end) or valor='Todo'))
) seguridad
on
a. REGION_ID = seguridad.REGION_ID
)

whay not use the same filter in the content tab of the logical table source?
check the physical sql sent to databse using web-admin-manage sessions-view log and see if there is any unexpected behavior. also run the same query in db and see iff you get the results in databse itself.

No row count in the Physical layer of the Administration Tool

Hi,
While creating physical layer, I imported tables and set connection pool.
After this, to verify connectivity, clicked Tools > Update All Row Counts.
Now according to Oracle online guide,
"when update all row counts completes, verify that the row counts are displayed in the Physical layer of the Administration Tool"
I do not see the row counts in the Physical layer of the Administration Tool. No error message gets displayed either.
Am I doing something wrong?
I am new to OBIEE.
Thanks in Advance & Regards,
Deeba

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.

Deeba

How to import tables to the physical layer of the Administration Tool.

Friends could help me with this issue. I'm just starting in OBIEE

Pass the filter to my physical layer view..

Hi,
My requirement is i need to pass the filter to my view (Physical Layer view).
Suppose if have a report with 4 or 5 prompts and 1 prompt am taking from that view (Physical Layer view).after running the report the query will be :
select a,b from x,(view (Physical Layer view)) where join conditions and where
prompt1='some value',prompt2='some value',prompt3='some value',prompt4='some value',prompt5='some value' (my prompts) (my prompts)
But my requirement is
select a,b from x,(view (Physical Layer view where prompt 5='some value')) where join conditions and where
prompt1='some value',prompt2='some value',prompt3='some value',prompt4='some value' (my prompts)
Hope you understand this..

Hi,
You want to pass the value from your dashboard Prompt to the physical layer view.
This can be achieved by using Request variable that you have the option of creating at the prompt level.
And then create session variable with the same name in RPD and now use that variable in the view created in the RPD physical layer in the where condition by calling the session variable.
Let me know if you need more info or if it does not work out for you.
Thanks.

Avoiding Rebuild of RPD for Change in Physical Layer Data Source.

Hi,
I would like to know whether change in physical layer data source will require rebuild of RPD or not.
Previously our client was using excel spread sheet as source of OBIEE 11g RPD for Phase – 1 of the project. Successive work (design of BMM layer, Presentation layer, subject area, design of report and dashboard etc) for that phase is complete on top of that.
Now, they would like to use Oracle database as source in Phase - 2, with the same table and column structure as MS Excel spreadsheet.
We have created connection type of OCI 10g/11g and successfully imported the metadata of the oracle database in the physical layer.
I was thinking whether it is possible to just redirect the source of physical layer from MS Excel to Oracle database, keeping the rest of the components (including BMM layer etc.) intact.
This will be pretty tedious job to rebuild all layers of the RPD again and again for change in the underlying database.
Please advise how this is possible. Many thanks !

I think..we can do some testing
you have created Alias for all tables.
Try checking view data by changing the Source name of any alias table to Oracle Source name in the physical Layer.
Check the datatypes of columns .
If these two are passed we can eliminate rebuilding.
Please post your comments.
