Count Measure by Minimum values in Dimension only

Question

Hi, I am drawing a huge blank here -
I have a Count measure on my fact table, and need to count the rows only if a code in the dimension table is the minimum code for the Fact
For my fact, I need to count from the following dims:
Dim A (count all from this dim - which would be a distinct?)
Dim B (count only the minimum code from this dim)
Any suggestions?
Thanks

Hi oroborus , you are basically trying to have two new measures in your Fact, based on some conditions.
Ex: You have a measure Total_Orders in your Fact and based on some conditions you want two new measures say Total_US_Orders and Total_OnLine_Orders.
Lets assume you have two dimensions Country_Dim and Store_Dim. which gives you location and Store of an order.
In your business model, duplicate the Total_Orders measure and name it as Total_US_Orders. Check the Use existing logical columns as the source box and go into the Expression Builder.
Here you define the formula for this new column. Which will be something like
FILTER(Fact.Total_Orders USING Country.Country_Code='US').
Similarly, create the Total_OnLine_Orders by duplicating the Total_Orders measure and write a formula something like
FILTER(Fact.Total_ORDERS USING Store.Store_Type = 'Online')
I hope this will give you a brief idea of how to create calculated columns in business layer.
Good Luck
