Creating dimension LEVEL with a VIEW

Question

Hello.
Because we don't have lots of HDD space we have created 5 views. (using some DBLINKS)
4 to dimension tables
1 to a fact table
When I try to create a level in a new dimension (OEM) using the WIZARD, for instance, I have to select a TABLE and select the attribute I want.
Can I use the VIEW instead of a TABLE??
Thanks
Peter

Answer 1

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;
