Earliest date from two fact tables as new query/parameter for date table

Hi DAST ,

In Power Query, I think your parameter code should look something like this:

// Start Date
List.Min(
    {
        List.Min(Query1[DateColumn]),
        List.Min(Query2[DateColumn])
    }
)

// End Date
List.Max(
    {
        List.Max(Query1[DateColumn]),
        List.Max(Query2[DateColumn])
    }
)
