Linking Multiple Fact table at different grains to the same dimensions

Hello Folks,

I am seeking your advice on dimensional modelling problem I have.

I am modelling two fact tables of Actuals and Budget which are at different granularity, Actuals are at day, customer and product sub category level. Budgets are at month, Region and Product catgeory level.Month, Region and Product Category is present in Date, Region and Procut Category dimension respectively. I have only three dimensions as Customer, Product and Date. Linking those dimensions to Actual Fact table is not an issue, what is the best way and options are there to link budget fact table to those three dimensions.

Please advise.

Regards,

Haroon
