New column based on multiple sorted rows

[MrMarshall]

Trying to create a new column based on multiple sorted rows within the same OrderNumber.

I have the following schema:

Description	OrderNumber	OrderRow
Art 1	30000	10
Art 2	30000	20
Art 3	30000	30
Art 4	30001	10
Art 5	30001	20
Art 6	30001	30

I want to make a new column with the Description of the rows with the lowest OrderRow value within the same OrderNumber.

Which would be: 

Description	OrderNumber	OrderdRow	New Column
Art 1	30000	10	Art 1
Art 2	30000	20	Art 1
Art 3	30000	30	Art 1
Art 4	30001	10	Art 4
Art 5	30001	20	Art 4
Art 6	30001	30	Art 4

I have no idea where to begin, probably due lack of DAX-syntax knowledge. Or maybe this is easier in the query editor.

Hi @MrMarshall,

You could create a calculated column with dax expression below.

New Column =
CALCULATE (
    MAX ( 'Order'[Description] ),
    FILTER (
        'Order',
        'Order'[OrderNumber] = EARLIER ( 'Order'[OrderNumber] )
            && 'Order'[OrderRow] = MIN ( 'Order'[OrderRow] )
    )
)

Then you will get your expected output.

Hope this can help you!

Best Regards,
