I have a requirement for dynamic security that I haven't been able to figure out. Not sure if it's a tool limitation or just requires more complicated DAX than I understand.
The requirement is to secure on a combination of Country and Business Unit. These are both attributes/master data fields. So I have a fact table, and then 2 dimension tables. (1 dimension table contains Country, 1 contains BU)
Below is an example from the Security table
| User | Country | Business Unit |
| Joe_Smith@abc.com | CA | BU025 |
| Joe_Smith@abc.com | US | BU026 |
When I try to add the DAX filter logic, I have to pick 1 of the dimension tables to apply the filter, and if I try to reference the column from the 2nd dimension table, I get an error during the syntax check.
"The column 'table2[Country]' either doesn't exist or doesn't have a relationship to any table available in the current context."
I was able to get this to work in a POC I did but both Country and Business Unit were on the same table in that example.
