We are developed a custom MOLAP engine for live processing a large amount of data in process. And now we got a requirement to integrate SSAS with our system. Dimension’s meta info and attributes data are very easy to get.
But how can I get facts data without making SSAS to calculate aggregates i.e. data that stored only on leafs?
Aggregates and calculations we perform ourselves.

Selecting data from SQL Database is not a solution because Cube while loading can perform joins, filtering. clearing of data etc.

Example:

Suppose we have Product Dimension:

  • Product.All
    +Product.Bread
    +Product.Chair
    +Product.Book

And facts table – Sales:

|Product|Qty|  
|Bread  | 1 |  
|Chair  | 3 |

I want to get from cube only real data, not aggregated one:

|Product|Qty|
|All    | 4 |  
|Book   | 0 |  
|Bread  | 1 |  
|Chair  | 3 |

    Try looking at DrillThrough in SSAS. This can display the fact-grain data, and is available in Excel as the default action when you double-click a cell. You can customise the result set, so long as all measures/dimensions come from the relevant fact table:
