Issues with data model and bidirectional filters

Hi Dear Community Experts, 

will be very grateful for any advice you can share on the issue based on the following data model:

 

 

As you can see I have 2 dimension (City and Code) and 2 fact tables. Coupone code is used as primary key for Code_dimension and city_id is used as primary hey for CityDimension table. Relationships are 1 to many. 

 

The issue is the following: each row in OffAdsTable has non null Coupon code, but in some cases channel is missing. Right now with this setup, when I prepare a visual based on Channel from OffAds table and sum(discount_amount) from Coupons split table calculations are wrong as sum(discount amount) is fixed and does not change when I try to change the channel or select several channels. I tried to use bidirectrional filters, but that does not solve my problem.  

 

Ideal solution I would expect will be some measure like Calculate(sum(discount_amount), filter context), which will enable change of calculation based on a column from one fact table to another based on relationships created with coupon code. 

Please let me know if you need clarifications on the issue. 

 

Thanks in advance!

 

Cheers, 

Saro

        Anonymous try this

         

        - relationship between code dimension table with offadd table and couple split table, it will be one to many one on code dimension table, 

        - change relationship cross filter direction to both, between code dimension and off add table

        - in table visual, drop channel and spending from off ads table and discount from coupon table 

         

        and I think that will do it.
