Hi

I am facing a issue ,as OBIEE generates multiple physical queries rather than 1 query for single fact.

It is grouping by different columns in  those multiple queries for a single report.

And this is affecting performance as well.

Can any one please suggest me the root cause for it and how to overcome this kind of scenario.

Thanks

Neethu

    Hi,

    Could you provide some more information please, this is quite vague.

    Could you paste the actual physical query your BI server is running (obfuscate any table names or subject areas as you want)? What does your model look like and what are the joins doing?

    Happy to help, but need more information

    thank you for your reply, I have a single report  and I am getting the query as below dividing it into multiple queries . I want to get a single query instead of these

    3 queries.

    select sum(T45014."EQUIPMENT_TEU_RATE") as c1,

         count(distinct T45014."DW_EQUIPMENT_KEY") as c2,
