Physical layer tables

I have a question on the physical layer. When we import the tables to the physical layer and after that there are few changes to the tables like adding or deleting columns. Do those changes reflect in the physical layer tables as well or do we have to import the modified table again to the physical layer and delete the previous table?

Hi,
After importing tables in physcial layer if you modify those tables in database those changes will not be reflected in physical layer.You dont have to import tables again if you add only one or more columns.You can simply create physical column in rpd with the same name and datatype as of database.In the same way if you delete any column in databse table then you can delete that column from RPD.
Thanks

Sql not supported in view in physical layer

hi, I wanna create a view (in physical layer)
table type = Select (under General tab in Phyiscal Table property)
I have checked the checkbox "Use database specific SQL".
and chosen "Oracle 9i" in Database tree.
the data structure in the table is in this thread methodology to get the result
the sql is
SELECT user,
MAX(decode(type,'A',value)) A,
MAX(decode(type,'B',value)) B,
MAX(decode(type,'C',value)) C
FROM tab
GROUP BY user
BUT when I click "View data" on the menu bar (right click the object in the phyiscal layer)
I get the error message.
Is max or decode not supported ? thanks

Could you please provide the error message that you are getting?

How to define join in physical layer between cube and relational table

Hi
I have a aggregated data in essbase cube. I want to supplement the information in the cube with data from relational source.
I read article http://community.altiusconsulting.com/blogs/altiustechblog/archive/2008/10/24/are-essbase-and-oracle-bi-enterprise-edition-obiee-a-match-made-in-heaven.aspx which describes how to do it.
From this article I gather that I have to define a complex join between the cube imported from essbase to my relational table in physical layer.
But when I use Join Manager I am only able to define jooin between tables from relation source but not with the imported cube.
In My case I am trying to join risk dimension in the cube based on risk_type_code (Gen3 member) with risk_type_code in relation table dt_risk_type.
How can I create this join?
Regards
Dhwaj

Hi
This has worked the BI server has joined the member from the oracle database to cube. So Now for risk type id defined in the cube I can view the risk type code and risk type name from the relational db.
But now if I want to find aggregated risk amount against a risk type id it brings back nothing. If I remove the join in the logical model then I get correct values. Is there a way by which I can combine phsical cube with relational model and still get the aggregated values in the cube?
I have changed the column risk amount to be sum in place of aggr_external both in logical and phsical model.
Regards,
Dhwaj

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....

Changing the LTS mapping in BMM layer to new Physical Alias table

Experts
I need to change the source table mapping in my BMM layer to new physical tables aliases.
I have finished BMM layer design (column name changes, business friendly names etc.) before actually creating the alias tables in the Physical layer and I know I hv to run for hiding now. I expected changing the logical source mapping to the new aliases will work but it's not the case though it works partially. Since the Column names are changed in the bmm, I have to manually change the Expression, Physical Table in the LTS column mapping tab for each non-matching name logical columns.
Column mapping is intact where both the BMM columns and the new Physical alias names match.
eg: CALENDER_YEAR(BMM) ---> CALENDAR_YEAR(Physical alias) mapping is intact but
Week Day(BMM) ---> WEEK_DAY(Physical alias) need to be changed manually.
Any tips/suggestions will be appreciated.
Regards,
Tom

Hi Tom,
I too do not see any other options here other than manually modifying the individual logical columns. When there is a new logical column, we have to map it manually to the physical column explicitly because the Admin tool will not know which physical column to pick up.
Hope this helps.
Thank you,

How to add a stand alone table from Physical layer to Business Model

Hi,
I have tables from 2 different database sources in my Physical Layer.
My Business model currently uses only tables from one database. from my second database in teh physical layer I need only one table and that will be a stand alone table, to my Presentation layer.
1. Does it have to go through my Business layer or can it be directly added to the Presentation layer. What are the steps?
2. Can I restrict the permissions on that stand alone table only to the administrator?
Thank you.

1)create a view with single column using the sql (select 1 from dual) in physical layer and join it with the table using complex join in physical layer (1=1).
Move that to BMM, set the column as key in both physical and bmm layer.
2) You can restrict the access for the table presentation layer
Double click the presentation layer table -> Permission -> there you can restrict the access by user or group
Thanks,
Vino

Probelm Addind new Table in Physical Layer, Create Dim in Business Model ..

I have completed a task for a dash board, that is running sucessfully.
Now I added a new table in "physical layer", (file->import->from database), table added successfully
Now, I droped this table in "business model", but when I want to create its dimension, there is no any option (when I right click on this table)
there are two cases
case 1:
I did not added modified fact table (with foreign key of new table) in "physical layer" and not in "business model and mapping"
case 2:
I added new table and modified "fact table (with foreign key of new table)" in "physical layer" and "business model and mapping"
but in both cases there is no "create dimension" button to create dimension
Please let me know the how to solve this problem, kindly define it in steps
thanks

Hi thr,
Create Dimensions is only available if the selected logical table is a dimension table (defined by 1:N logical joins) and no dimension has been associated with this table.
In you case, once you have imported the table successfully in physical layer, then join your table to fact table. Drag n drop in BMM under a new logical table and then join it to BMM Logical fact using complex join. Now, if you right click, you see the last option as 'Create Dimension'
Hope you find it useful..

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.

How to Move from CSV to Table in Physical layer in Best possible way

We had a project which had the source (physical Layer) as CSV. Now there are moving from CSV to a Table in the Database.
Can anyone guide through the best possible way to complete the task
With Regards!
Steve

Create a new Database node in the Physical layer with connection pool, create a schema folder and drag your CSV object into the new database - All your BMM mappings and hence Presentation objects will move over seamlessly.
Might be an idea to simply reverse engineer / import any object from your database to initially create your database connection / tree then simply drag the CSV into it.
Hope this helps,
Alastair

Joining tables across databases in OBIEE Physical Layer

I was facing this problem of joining tables across databases in Physical layer of OBIEE admin tool.
I had a requirement to combine two tables from 2 different databases A and B respectively. I had created one database object (OBIEE Object) in the physical layer and I had created two connection pools under that pointing to the required databases. I was able to view the data (right click on the table object --> popup menu option "View Data" ) though I had to go through the "Select connection Pool" window and select the required connection pool. I was able to join the tables and was able to complete the star schema in BMM and bring them up to the presentation layer. Conistency check was also successful. Everything went fine so far.
But when I started building the report, I started getting error whenever I chose the table which was supposed to be queried by using the second connection pool. The error message was something like "table or view does not exist at OCI call OCIStmtExecute". I assume that this was happening because the systm was not able to understand which connection pool to choose (because there were two pools defined under one database object) and by default the server was choosing the first one. If anybody is having a different opinion or definite information about this, kindly update with your reply.
I could resolve this problem after creating a separate database object with a separate connection pool defined under it, which points to the second database. Imported the required table under this database object. (Infact it was reverse. When I re-imported the table, OBIEE Admin tool, by default created its own database object and the connection pool separately for the imported table).
Once this was done then I went ahead as usual by joining the tables across these two different database objects and modelling was already done (ofcourse with a little more tweaking since the mapping had to be redone between BMM and Physical layers). Now I could build the report in the reporting layer without encountering any error.
Appreciate and welcome any further additions/updations/corrections regarding this issue(?).

Duplicate table in physical Layer

Hi,
I've created a duplicate table in physical layer , When i check view data on duplicate, getting an error. (Table or view doesn't exist). How to get out of it.
Regards,
Sri

When you duplicate a table, you create a new physical table with a new name. If this table is involved in a query, the SQL FROM clause will list this table. If the table does not exist in the database, then an error will occur.
Creating an alias creates a copy of the table in metadata that will be referenced in SQL with a new alias name. The alias name in SQL will be derived from the ID given to the alias in the metadata.
The important point is that you are not creating an object in the metadata that requires you to create a new object in the physical database. If you duplicate a table in metadata, then that new table must map to a separate table in the physical database. If it doesn't exist, you will need to create it or you will get a SQL error

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

Alias Tables and Duplicate tables in Physical Layer

Hi all,
I have a small doubt in physical layer. We have two options when we right click table, 'Alias' and 'Duplicate'. To create another instance of a table, can we use any one of these. Does it make any difference
Thanks & Regards,
Jagi

Hi,
If u duplicate any table the join conditions will carry with respective tables , same name appending (TableName#1)
In case of alias u need to specify joins conditions explicitly
We can use same table with different constrains to the same table
Aliases used, if you need to replicate a physical table and not create multiple tables with the same data
If you delete any column in the Original table automatically deleted in alias
table and Its not reflected in Duplicate table.
Steps:
Right Click the original table. Choose New Object and choose Alias.
The mistake most people make is try to bring in the same table again and rename it or choose Duplicate by right clicking the original table.
Thanks,
Balaa...
