Sum with filter and cross table

[John117]

I have 2 tables, one with the date, customer name, and the gross sales and another table that is a selection of the most relevant customer by date, like this:

Table 1

Date	Customer	Gross Sales
01/06/2020	X	300
01/06/2020	Y	200
01/07/2020	Y	100
01/07/2020	Z	150

Table 2

Date	Customer
01/06/2020	X
01/07/2020	Y
01/07/2020	X

I need to calculate the total sales of the most relevant customers, but it's not working. I'm using this formula:

Total gross = calculate(sum(Table1[Gross Sales]), filter(Table1, Table1[customer]=values(Table2[customer])))

The error message says 'MdxScript(Model) (4,102) Calculation error in measure: A table of multiple values was supplied where a single value was expected'

Could someone help me? I'm beginner in Power BI

Hi @John117 ,

VALUES() returns a single column table or a table of the same columns. In your scenario, VALUES(Table2[customer]) returns a table with a single column. Your problem is that a column cannot equal a table. You can use IN instead of “=”.

---

IN

Creates a logical OR condition between each row being compared to a table. Note: the table constructor syntax uses curly braces.

'Product'[Color] IN { "Red", "Blue", "Black" }

---

The formula can be modified as follows:

Total gross 2 =
CALCULATE (
    SUM ( Table1[Gross Sales] ),
    FILTER ( Table1, Table1[customer] IN VALUES ( Table2[customer] ) )
)

The result is shown in the following figure:

The above formula is limited to filtering customer names. If you also want to filter by date and customer name at the same time. You can write a calculated columns or a measure.

You can write your calculated column like so:

Total gross =
CALCULATE (
    SUM ( Table1[Gross Sales] ),
    FILTER (
        Table1,
        Table1[customer] = 'Table2'[customer]
            && Table1[Date] = Table2[Date]
    )
)

The result is shown in the following figure:

Or you can write your measure like so:

Total gross3 = 
VAR table3 =
    ADDCOLUMNS (
        Table2,
        "Total gross4", CALCULATE (
            SUM ( Table1[Gross Sales] ),
            FILTER (
                Table1,
                Table1[Customer] = Table2[customer]
                    && Table1[Date] = Table2[Date]
            )
        )
    )
RETURN
    SUMX ( table3, [Total gross4] )

The result is shown in the following figure:

Yes, VALUES() returns {X,Y}  from Table 2.  Don't you also want to filter by date? And correct your sample data in Table 2?
