Create Dimension in 9i/10g

Hi all.. Happy New Year 2005.
Is there a possibility that I can create dimension using normal view or materialized view.
OEM (both 9i and 10g) only provides the table names in the drop down.
If I can create how can I?
thanks in advance.
Saumen

I just tried this in 10g 10.1.0.3 with all the latest patches. Looks like OEM can use tables or MVs, but NOT views.
Maybe you could build a temp table that looks exactly like the view and use that to get the generated SQL to build the dimension, then do a find and replace to change the table name to a view name?
Let us know if that works!
Thx,
Scott

Problem while creating Dimension in AW...

Hi
I m facing error while creating the Dimension in AW.
i have done the following steps.
1.I have created the AW name "myfirstaw" and i can see the AW in my DB.

Is it possible to create dimension roles in AWM?

Hi,
Is it possible to create dimension roles in AWM like the way we have in OWB ?
If yes, please direct on the way to do this.
Many thanks in advance for your kind inputs.

I think what you need is to use the ALIAS option that is part of the DEFINE DIMENSION statement
DEFINE DIMENSION ALIASOF
The DEFINE DIMENSION ALIASOF command defines a dimension alias for a simple dimension. An alias dimension has the same type and values as its base dimension. Typically, you define an alias dimension when you want to dimension a variable by the same dimension twice.
Additionally, You can use a LIMIT statement to limit alias dimensions and define variables and relations using an alias dimension. However, you cannot maintain an alias dimension directly; instead you maintain its base dimension using MAINTAIN.
Syntax
DEFINE name DIMENSION ALIASOF dimension [TEMP] [AW workspace] [SESSION]
Arguments
name
The name of the object you are defining. For general information about this argument, see the main entry for the DEFINE command.
DIMENSION ALIASOF
If you look at this example if provides a great example of how to use this feature:
http://download.oracle.com/docs/cd/B19306_01/olap.102/b14346/dml_x_decimal006.htm#ABC1485326
But of course the main issue here is how to generate the standard form metadata required to support this feature and make the dimension alias avaliable and visible within AWM. That is the difficult (and I would say impossible) part of the process since this feature is not supported by the AW XML API (at least I don't think it is, you could check the API docs to see if this is supported). if it is not supported then the management of this feature would all have to be controlled via OLAP DML commands (load dimension members etc) but you would still not be able to include it within a cube definition and then maintain that cube using AW XML API.
Does that help?

Unable to create dimensions in schemas that use synonyms

I have three schemas (s1, s2 and s3) that use synonyms to reference different tables. S1 and S2 have all tables, equally distributed in their schema. S3 is an end user who has just synonyms.
I tried creating dimensions in any of them, table or view not found error is encountered.
I created required tables in my schema (user: meka) and I was successfully able to create dimensions. The following command worked in "meka", not any of the three schemas (s1, s2 and s3).
CREATE DIMENSION country
     level city_id is lu_city.CITY_ID
          level state_id is lu_state.STATE_ID
          level country_id is lu_country.COUNTRY_ID

I tried a few combinations, including specifying fully qualified table names (s1.lu_city.city_id, etc); created views at user S3 tried the same. All of them were unsuccessful. I am using Oracle 11g R2, here is screen shot:

Unable to create dimension in Analytic Workspace manager

Hi all,
I am trying to create dimension using Analytic Workspace Manager(AWM) and it throws the following error.
*"The transaction is not committable: "java.lang.RuntimeException: org.xml.sax.SAXException: Missing XML attribute: Attribute for tag: <Metadata><StandardDimension><Organization><AWPrimaryDimensionOrganization><AttributeOrganization>"*
Kindly share your comments.
I am using Oracle 11g r1 client to connect with oracle 11g R2 database.
Please let me know the steps to create a OLAP cube using AWM

It sounds like a mismatch between an old version of AWM and a new version of the server. Please try a more recent version of AWM.

BI Administration Tool - Create Dimension automatically

I installed Oracle Business Intelligence Standard Edition One Release 10.1.3.2.1 and I'm following "Business Intelligence Standard Edition One Tutorial" ( [Tutorial - section 4.3.5|http://download.oracle.com/docs/cd/E10352_01/doc/bi.1013/e10312/repository.htm#CBAHDGAA] )
I would set up a dimension automatically from a logical dimension table by means of "BI Administration Tool 10.1.3.2.1". So I follow the steps of this tutorial and even the Administration Guide ([section "Creating Dimensions Automatically" pg 134|http://download.oracle.com/docs/cd/E10415_01/doc/bi.1013/b31770.pdf]) :
Particularly:
1)In the Administration Tool, I opened a repository.
2)In the Business Model and Mapping layer of a repository, right-click a logical table.
3)From the right-click menu, I should find and choose Create Dimension.
but on the right-click menu I can't see Create Dimension.
Could you please suggest me the reason?
Any ideas will be much appreciated.
Marco
Edited by: user1005030 on 21-ago-2011 3.18

Marco,
You will not see the option for "Create Dimension" when right-clicking a logical table in the BMM Layer if that logical table is:
1. Already being used as a dimension (icon with 3 prongs)
2. Not joined correctly with the Business Model (i.e. Either not joined at all or it is joined as a Fact table and is not acting like a dimension table to the Admin Tool)
My hunch believes that you have already associated the logical table with a dimension/hierarchy. To run a litmus test, just delete all of the dimensions you have created for the Business Model, then right-click the logical table in question. If you see the "Create Dimension" option then you know what the issue is.
Let me know if that helps.

How to create Dimension group in ATG-endeca ecommerce application

We have requirement where we have to specify dimensions and their schema from BCC in ATG. Now the problem is we want to dimension groups and we don't see anywhere in documents to create it. Since this dimensions are created through FCM so we are not able to see in /config/pipeline directory but we see only in processing directory. So we don't see any means to create dimension group through dev studio too. Please tell us how we can do it.

we have to do it through EP interface through BP TMS.
1. connect EP to SAP system
2. Configure all the iviews of TMS business package so it can communicate with SAP system (change only SAP system name for all iviews)
3. Assign the roles to user of EP
4. run application using TMS

Using the CWM1 views through Enterprise Manager Dimensions/Lookups must be TABLES, fact tables can be VIEWS
In the CWM2 set up you can utilise VIEWS for all componenets. Furthermore, my data mart has a distributed environment where reference data is physically located in a remote database.
In order to reference the remote tables I have considered database synonyms, but this did not work.
Secondly, we created a number of views containing DBLINKS to the remote database. This works but performance can be poor because the SQL generated by the BI Beans, makes several calls to the complex view to create hierarchies, retrieve selections etc. which can be inefficient.
I think my next steps will be to create Materialized views on the data mart from the remote reference database.
Finally, run the following statement before your CWM2 statements. cwm2_olap_manager.Set_Echo_ON will provide a complete output from your statements rather than just "Procedure Completed Sucessfully"
SET ECHO ON
SET LINESIZE 120
SET PAGESIZE 50
SET SERVEROUTPUT ON
execute cwm2_olap_manager.Set_Echo_ON;

Can CWM2 API creating dimensions and cube reference a view

Can CWM2 API creating dimensions and cube reference a view instead of a table.
Can the following API reference a view instead of table
For creating dimensions
CWM2_OLAP_TABLE_MAP.MAP_DIMTBL_HIERLEVEL
CWM2_OLAP_TABLE_MAP.MAP_DIMTBL_HIERLEVELATTR
For creating cubes
CWM2_OLAP_TABLE_MAP.MAP_FACTTBL_LEVELKEY
CWM2_OLAP_TABLE_MAP.MAP_FACTTBL_MEASURE

Hi!
Yes!
And I am using views sometimes.
I am reading at this moment also the following...
maybe someone can explain me this sentence...
MULTIPLE FACT TABLES:
"The CWM2 APIs also support multiple fact tables per cube. In this case, the data
associated with a given combinations of hierarchies can be stored in a separate fact
table. All the fact tables associated with a cube must have the same column
structure."
I get a fetch error message..'cause of this.
What does it mean by "the same column
structure" ???

What prerequisites shd be taken while creating dimensions in an mp?

hi all,
What are the pre-requisties should be taken while creating dimensions nor creating an multiprovider.
Can anyone list me out the pre-requisites. and send me some docs if u have to my email id [email protected]
regds
thanxs in advance
hari

Hi Hari,
that is completely depend on your Reporting requirement... how you want to generate your report.. on which object you want to analyse the report .... that object should be take in one dimension... based on that you need to design dimensions.. so, first of all every modelling is based on complete Report requirement..
Multiprovider means.. it just provide union operation only.. so, what are the fields you want .. those fileds only you can take from sources and based on your reporting requirement you can create dimensions..
