VAR _Perspectives = 
    SELECTCOLUMNS(
        INFO.PERSPECTIVES(),
        "PerspectiveID", [ID],
        "Perspective Name", [Name],
        "Perspective Description", [Description],
        "Modified", [ModifiedTime]
    )

VAR _PerspectiveTables = 
    SELECTCOLUMNS(
        INFO.PERSPECTIVETABLES(),
        "PerspectiveID", [PerspectiveID],
        "TableID", [TableID],
        "IncludeAll", [IncludeAll]
    )

VAR _Tables = 
    SELECTCOLUMNS(
        INFO.TABLES(),

    )

VAR _CombinedTable1 = 
    NATURALLEFTOUTERJOIN(
        _Perspectives,
        _PerspectiveTables
    )

VAR _CombinedTable2 = 
    NATURALLEFTOUTERJOIN(
        _CombinedTable1,
        _Tables
    )

RETURN
    SELECTCOLUMNS(
        _CombinedTable2,
        "Perspective Name", [Perspective Name],
        "Perspective Description", [Perspective Description],
        "Table Name", [Table Name],
        "Include All", [IncludeAll],
