ISBLANK does not refer to data

[Anonymous]

Hi there, 

it is my second day with power BI. 

I want to display missing data (nulls) in each of field (non numeric). I dont know if that is the best approach but i have decided to create meassure like:

MissingActors = ISBLANK(Merge1[result.actor]))

and then summarize it.

but i get this:

A single value for column 'result.actor' in table 'Merge1' 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.

How can i solve this?

@Anonymous ,

You need to add an aggregation like below:

MissingActors =
ISBLANK ( MAX ( Merge1[result.actor] ) )

Hi @Anonymous 

Try:

MissingActors = 
SUMX ( 
    Merge1,
    ISBLANK ( Merge1[result.actor] )
)

Hello @Anonymous,

May I have sample data or fields that are being used?

Try

MissingActors = calcaulte(countrows(Merge1), ISBLANK(Merge1[result.actor]))
