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

Hi TJCappy

please try

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

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.
