External Reporting Link - LevelID
When using the External Reporting Link, The Rooms table has LevelID, but it is always NULL. Could this be fixed, and/or could the room table also export the Level Name? I have no way of filtering a list of rooms by level in Power BI without manually exporting the standard Room report, which DOES have both these values and then linking them together. This is an extra manual step that could easily be messed up.
