Handling with two separated agg tables

Hi there. I have a huge fact table with approximately 200 million rows.

 

I need to reduce the model size by using aggregations. So I created two principal aggregation tables: dates (4k rows) and sellers (40k rows).

 

The question is: how can I work with both of them? For example: sales by seller x on date y?

 

P.S.: I can't create a table with both seller and date because it would be huge as well (40k * 4k = 160 million rows).

Need Help

    Hi,

    Create a relationship (Many to One and Single) from the 2 Fact tables to the 2 Dim tables.

      I did this, but it doesn't find the aggregation relationship between seller and date in the same table (obviously because they are in separate tables). Is there any way for the two tables to interact even though they are separate?
