DAX function "RELATED" does not work between DirectQuery and Import tables.

[Anonymous]

When using the DAX function "RELATED" to add a new column from an Imported table to a DirectQuery table, I receive an error. This error does not occur if both tables are using DirectQuery.

Column: SampleColumn = RELATED(ImportTable[Column])

Error: "The column 'ImportTable[Column]' either doesn't exist or doesn't have a relationship to any table available in the current context."

Relationship: DirectQueryTable[SampleKey] (many) has a relationship with ImportTable[SampleKey] (one)

Cardinality = Many to One (*:1)

Cross filter direction = Both

Make this relationship active = Checked

Note: When creating the column using "RELATED" in the DirectQueryTable table, ImportTable shows up as a suggestion.

4 years and counting, almost 5.

So do we think that Microsoft cares enough to fix this problem after it has been an open issue for over 4 years? Many Power BI users will use a DirectQuery / Import and add tables to it, but we cannot use the same DAX functions as if we built it from scratch. It would seem like Microsoft would want to resolve this quickly.

This problem is OVER 5 YEAR OLD now, @Microsoft .
