Interactive Visuals between 2 Fact tables
What i did i create as a bridge dimension table in which i have in the same row the Sales and Purchase and 2 Fact tables FT_SALES and FT_PURCHASE, in the Purchase table i have also the SALES_NR since it's a shortcut of the Purchase_nr. Then i linked the FT_SALES with bridge table with one to many relationship and the Bridge table with FT_PURCHASE with many to many through the SALES_NR. That way i have my tables interactive and when i want to link a different table to both i use the TREATAS function that you suggested me in a different post ! lbendlin
This depends on the business questions you are trying to answer. Usually a clean snowflake schema with separate fact tables is better, but there are cases where you need to use a different data model to answer the questions.
