Cannot create measures on a date column in Analysis Services Model and in Power BI Desktop

Hello community members,

 

I am hoping you could provide some insight in what I am trying to achieve in both the AS model and in PBI Desktop.

 

Apart from the dates table I have created in the AS model, there are of course more tables in the model that have date columns, such as Purchase Order Creation Date, Purchase Order Update Date etc. If I want to create a measure on these columns, for example a simple DATEDIFF, the DAX formula editor will not let me select the right column. It seems that it only comes up with suggestions for other (already created) measures, which are completely unrelated to the table/column I want to create it on. For example, it is giving suggestions to do the DATEDIFF on a Count Amount column... If I type in the table and column name myself, it gives that squigly line telling me that it can't find that name. 

 

This is happening both in the model as well as the report level measures and I can't find the reason for the life of me. 

 

Can anyone help me out?

 

Thanks in advance, 

 

Thomas

  • Anonymous if you adding a measure, you cannot directly use the column, you have to use some sort of aggregation, so you can say DATEDIFF ( MAX ( Table[Date] ), MAX ( Table[Date2] ), MONTH )

     

    so MAX will be used as aggregation, now not sure if you want to add this as a measure? Maybe you want to add this datediff as a column but that is a separate point.

  • Hi Anonymous ,

     

    The parameters in measure cannot be columns directly. You could refer to the following DAX:

    Measure =
    DATEDIFF (
        SELECTEDVALUE ( 'Table'[Start Date] ),
        SELECTEDVALUE ( 'Table'[End Date] ),
        DAY
    )
