Major Description
DimensionX has dimtableA. dimtableA has a partition column dt which is the time dimension partition. it also has suppose a partition column "source". when one queries "cube select x from DimensionX where source=xyz", lens complains:
No dimension table has the queried columns for user_owned_apps, columns: [xyz, source]
This is because lens doesn't identify the "source" partition column as a column of dimtableA
