Hi,

I have a table "Product" in my Database , which i am using to create reports in OBIEE. The table has five cols : ID, Version, Date, ItemName, ItemRate . It is partitioned on Date col . The table has many rows and I want to hit Date partition to improve performance.I take Date as input from user by Date Prompt.

The primary key is ID+Version+ItemName


I want to get a table which contains Date, ItemName,ItemRate, ID for each ID with max(Version). This table I will join with another table in Oracle BI Answers to generate reports. If an ID has many versions, I get max version value and then return ID,ItemName,ItemRate,Date corresponding to that Verion value.

What is the best way to achieve this, should I define view in my physical layer which contains sql query for simplified table so that it will make my task of generating reports easier by having asimplified table in Oracle BI Answers ? ?

Please ask if any clarification is needed ....

Thanks
