"The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value."

Hi,

 

I'm using the following equation:

=AllExcept(Tablename, Tablename[ColumnName])

 

And I get the following error:

"The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value."

 

How could I be getting this error if I'm specifying one column per the formula.

 

Thanks

Hi @Anonymous

Do you use this formula inside another formula or just put this formula in a measure or calculated column?

ALLEXCEPT would return a table with all filters removed except for the filters on the specified columns.

Thanks Maggie,

 

Fundamentally, does a measure produce a single output which can produce multiple outputs only when the context is iterated on and changed?

 

For instance, if I had a table like:

- Color -

Red

Red

Blue

Yellow

 

And I made the following measure:

Values(Color)

 

Would it never produce the below column because the below column contains multiple values and thus produce a similar error as the one I'm experiencing?

Red

Blue

Yellow

 

Thanks again,

Buri

 

Edit: I see what you're saying. I was trying to pull this out of a larger formula so I could test it's output and adjust accordingly.  Thanks!
