Convert row into value

[Anonymous]

Dear DAX collegues,

I stumbled over a - maybe - trivial problem, but cannot solve it:

I'd like to create a measure that give the name of the product with max production duration per day.

I've got one table that has [Product], [Minutes] and [Date]

The second table shows the used raw materials per Date - here I'd like to create the measure.

For a given day, I have e.g. three product produced:

A   340 min

B   700 min

C  194 min

I tried to use TopN(1;'Products;Products[Minutes];DESC)) to give the top 1 row of the products (= B | 700 min).

But now, this result is obviously a single row, but what I do like to have now is just the value "B".

Thanks in advance for your ideas!

Hi @Anonymous

You may try to use below measure:

Measure =
CALCULATE (
    VALUES ( 'Product'[Product] ),
    TOPN ( 1, 'Product', 'Product'[Minutes], DESC )
)

Regards,

Cherie

you can use the syntax you posted as filter parameter in CALCULATE

Measure = 
VAR Top1 = TopN(1,'Products',Products[Minutes],DESC)
RETURN
CALCULATE(FIRSTNONBLANK(Products[Product],TRUE),Top1)

Great! Works absolutly fine!
