Hi everybody,
I would like to create manuals aggregations to improve some MDX requests. (in SSRS Reports)
When I'm reading OlapQueryLog table, i see this Dataset:
10000011001000000,00000000000000000000....
1000002300400....
The first dimension is a time dimension with these selected attributes:
- Days
- Months
- Trimester
- Year
=> All Attributes is designed like hierarchy into "Attribute Relationships" of the "Time dimension"
- I create aggregation with "Day attribute" and it improve performance but not enough to speed up my request.
- I create 3 another aggregations : One on "Day attribute", one on "Month", one on "Year" => Nothing change
- I create another one with "Days", "Months", "Trimester" and "Year" (I don't worry about the BIDS warning on the unvalidated Aggregation) => Nothing change
My questions:
Thanks all for your responses.
Arnaud
