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

[hosea_chumba]

Kindly assist on the below;

I get the error "The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value"  when i input the below formula to create a column. How do i solve it.

Inadequately secured loans =

VAR _inadequate_security = CALCULATE(FILTER('Table1','Table1'[Collateral Amount] < 1.5*'Table1'[Loan Amount]

 && 'Table1'[Product ID] <> {2222,8888}))

VAR _result_ = SWITCH(TRUE(),

_inadequate_security,"Inadeqaute Security",

"Adequate Security")

RETURN

_result_

Objective is to identify transactions that have collateral value that are not at least 150% of the loan amount excluding product 2222 and 8888

It's possible to have calculated tables inside a measure but if you want to return a table, then you need to use CALCULATETABLE rather than CALCULATE. However, since you are using _inadequate_security_ inside a SWITCH as if it is True/False, I suspect that you meant to have an argument in CALCULATE other than the filter table.

Did you intend to write something like this? (Note the line before FILTER.)

Inadequately secured loans =
VAR _inadequate_security =
    CALCULATE (
        ISEMPTY ( 'Table1' ),
        FILTER (
            'Table1',
            'Table1'[Collateral Amount] < 1.5 * 'Table1'[Loan Amount]
                && NOT ( 'Table1'[Product ID] IN { 2222, 8888 } )
        )
    )
VAR _result_ =
    SWITCH (
        TRUE (),
        _inadequate_security, "Inadeqaute Security",
        "Adequate Security"
    )
RETURN
    _result_

Hi there.

First and foremost, is this a measure? A calculated column?

The error you get stems from the fact that you cannot use CALCULATE to calculate tables in it, only scalar values, but FILTER does return a table, so it can't be used with CALCULATE as the first argument. The CALCULATE that you have wrapped FILTER in is totally unnecessary and, indeed, incorrect in this place. Also, please bear in mind you cannot return a table from a measure. Only scalar values are possible.

Incidentally, you have posted this question on a forum that deals with Power Query, not with DAX.
