Filter a table based on multiple values from another table

[obriaincian]

I have the below calculation that should take an email address, filter the roles table for that email. It should then filter the Master table Company column for the same companies as in the filtered roles table.

Note, testing@test.com can have multiple companies.

The error I'm getting is 

The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value.

FilteredMasterTable = 
VAR SelectedEmail = "testing@test.com"
VAR SelectedRoles = 
    CALCULATETABLE(
        VALUES('Roles Table'[Company]),
        'Roles Table'[Email] = SelectedEmail
    )
RETURN
    FILTER(
        Master,
        Master[Company]IN SelectedRoles
    )

Hi, @obriaincian 

Can you provide sample data for testing? Sensitive information can be removed in advance. What kind of expected results do you expect? You can also show it with pictures or Excel. I look forward to your response.

Note: I want to implement this as Row Level Security but I am testing it in a measure first
