    Hi Anonymous 

    Do you use the formula in a measure as below instead of a column?

    If so, please modify the formula as below to use in a measure

    CompletionStatus =
    SWITCH (
    TRUE (),
    MAX ( TasksOpportunities[Status] ) = "Open"
    && MAX ( TasksOpportunities[Days until Completion] ) < 0, "Open",
    MAX ( TasksOpportunities[Status] ) = "Open"
    && MAX ( TasksOpportunities[Days until Completion] ) >= 0
    && MAX ( TasksOpportunities[Days until Completion] ) < 7, "Open",
    MAX ( TasksOpportunities[Status] ) = "Open"
    && MAX ( TasksOpportunities[Days until Completion] ) > 7, "Standby",
    MAX ( TasksOpportunities[Status] ) = "Completed", "0",
    MAX ( TasksOpportunities[Status] ) = "Cancelled", "3",
    BLANK ()
    )

     

    Best Regards

Hi Maggie,

Thanks for the explanation, this totally makes sense. 

Nevertheless I did get another error message when I tried your expression: 
A single value for column 'Status' in table 'TasksOpportunities' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.

 

Do you know why this is and how to solve it?
