Error de Power bi

[john_snake]

a que se debe que al realizar una medida en Dax, no me detecta la tabla y su columna de referencia?

Hi @john_snake ,

Because for some function, measure can only refer to one value, and there are multiple values ​​in tables and columns. 

If you reference a column in a measure, you must wrap the column in an aggregation function like MIN, MAX, SUM, AVERAGE, etc.
