How to count the number of boolean "1" based on criteria?

[Anonymous]

Hi, I have two tables; table 1 and table 2.

I am trying to count the number of rows containing "1" on the shift count column from table 1 on table 2's total shifts column BASED on staff's name in table 2's staff column.

Here is table 1 and Total Shifts column shows the outcome that I want from the DAX expression:

Staff	Total Shifts
Name1	2
Name2	1

Here is table 2:

Staff	Shift Count
Name1	1
Name2	0
Name1	0
Name2	1
Name1	1

The DAX expressions that im using are Counta and Filter. It did not work and I get an error message "Dax Comparison operations do not support comparing values of type Integer with values of type Text. Consider using the VALUE or FORMAT function to convert one of the values":

Please note, shift count column's data type is whole number.

Total Shift =

CALCULATE(

    COUNTA('Table 2'[Shift Count]),

            (FILTER(ALL('Table 2'),

            'Table 2'[Shift Count] = 'Table 1'[Staff])

            )

)

Hi @Anonymous 

Try this

Total Shift =
CALCULATE(
    SUM('Table 2'[Shift Count]),
            (FILTER(ALL('Table 2'),
            'Table 2'[Staff] = 'Table 1'[Staff])
            )
)

Please mark the question solved when done and consider giving kudos if posts are helpful.

 Cheers

Even better is this:

Total Shift = // calculated column in Table 1
CALCULATE(
    SUM('Table 2'[Shift Count]),
    'Table 2'[Staff] = SELECTEDVALUE( 'Table 1'[Staff] )
)

Best
