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

Hi All,

Based on the sales for a given period, I am trying to calclate the number of clients a sales rep will need to have to attain their sales goal.

I have the following data and can't seem to get the result I need and continuously get the above noted error.

I have a table that has the Sales targets for each role in the department

Role                                2022 Annual Target              2023 Annual Target

Account Rep - Level I              14,000,000.00                       14,500,000.00     

Account Rep -Level II               19,000,000.00                      20,000,000.00

I then have a measure that Calculates the avrerage sale per client per rep

Distinct Client Gross Sales Average =
DIVIDE (
    'DailySales (cds) Measures'[Total Gross Sales Amount],
    'DailySales (cds) Measures'[Clients with Sales trxns in period],
    "null"
)

I am now trying to create a measure that will  divide the target for each rep by the Distinct Client Gross Sales Average to get the a target number of clients.

the measure I have created is 

Clients Needed for Target =
VAR Target =
    CALCULATE ( 'Targets', 'Targets'[2023 Annual Target] )
VAR AverageSale =
    CALCULATE ( [CNM Distinct Client Gross sales Average] )
RETURN
    Target / AverageSale

But it does not work and no matter what I try based on all the info i have come accross on the net I am having no success.

I could really do with some help.

Thanks

Thank you that worked,

If you have the time and patience, would it be possible to explain why. I guess it has something to do with the Table "Targets" but can't figure out the reason for the error.  thanks again.

@TJCappy 

The first argument of CALCULATE has to be sn expression that yields a scalar value but you have specified a table ('Targets').  The second argument of CALCULATE if a Filter expression (in other words a table)

Thank you for explaining, it now makes sense. I am still pretty green with Power BI so getting an explanation really helps.

Hi @TJCappy 

please try

Clients Needed for Target =
SUMX (
'Targets',
DIVIDE (
'Targets'[2023 Annual Target],
[CNM Distinct Client Gross sales Average]
)
)
