TopN in Dax not working

[rpinxt]

Trying to make a (I thought) simple TopN measure like :

Top5_BO_Qty = TOPN(5,'Backorder Details',[BO Qty],DESC)

But getting this error:

Anybody that can help me out and tell me whats wrong and how to fix?

I want the Top 5 on field PF name (it will not let me choose that field only the table Backorder details) based on BO Qty.

Hi

Do this

Top5_BO_Qty =
    TOPN(5,
    ALL('Backorder Details'[yourfield]),
    [BO Qty],
    DESC)

Thanks @jcalheir 
Did this :

Top5_BO_Qty = TOPN(5,

    ALL('Backorder Details'[PF Name]),

    [BO Qty],

    DESC)

** How did you get that grey box around your code?

But still no luck:

It is a card, so just to check the one value measure.

Is it possible to share your PBIX file so we can take a look?

Ok had to throw out a lot because it work data, but still the field from the measure are there and also the error.

So hopefully this example is enough to solve it.

I cannot add a file here so I put it on drive:

Sorry, i was just looking at the function and forgot to calculate the measure.

This works

Top5_BO_Qty = 
CALCULATE(
    [BO Qty],
    KEEPFILTERS(
        TOPN(
            5,
            ALL('Backorder Details'[PF Name]),
            [BO Qty],
            DESC
        )
    )
)

Kind regards,
José
