Help me to write the DAX formula using Filter Function to Link Tables

[Anonymous]

I have the four following table:

Table 1: (Main Table)

Date	ID	Full Time Equivalent
30/06/2023	100	30.0
30/06/2023	200	20.0
31/05/2023	100	30.0
31/05/2023	200	20.0

Table 2: (Primary Key)

Date Key

30/06/2023

31/05/2023

30/04/2023

31/03/2023

Table 3: (Primary Key)

ID Key

100

200

300

Table 4: (ID Table)

Date	ID	Team	Department	Division
30/06/2023	100	XYZ	MNO	OPQ
31/05/2023	100	ZXY	MNO	OPQ
30/04/2023	100	ZXY	LOM	OPQ

Here are the relationship details:

1) Table 1 [Date] > Many to One>Table 2 [Date Key]>One to Many> Table 4 [Date]

2) Table 1 [ID] > Many to One>Table 3 [ID Key]>One to Many> Table 4 [ID]

As the ID moves to various teams and departments every month, I need to create a measure that will give the summation of full-time equivalents by date, department, division, etc. as follows:

FTE = CALCULATE(

SUM(Table1[Full Time Equivalent]),

FILTER(Table 4, Table 4[Date] = 'Table 2'[Date Key])

)

This measure will first filter Table 4 in the Date column. Then, it will calculate the sum of the full-time equivalent column in Table 1 for the filtered rows. It is showing an error as follows: "This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result."

Can anyone please help me write the formula so that FTE will filter by date, department, division, etc.?

@Anonymous ,

FTE =
CALCULATE (
    SUM ( 'Table 1'[Full Time Equivalent] ),
    FILTER ( 'Table 4', 'Table 4'[Date] = SELECTEDVALUE ( 'Table 2'[Date Key] ) )
)

Thanks @ERD. Unfortunately it shows the following message: Failed to resolve name 'SELECTEDVALUE'. It is not a valid table, variable, or function name.

@Anonymous , are you using Excel or PBI? Try this:

FTE =
VAR dt = MAX (  'Table 2'[Date Key] )
RETURN
CALCULATE (
    SUM ( 'Table 1'[Full Time Equivalent] ),
    FILTER ( 'Table 4', 'Table 4'[Date] = dt )
)

Hi @Anonymous 

Please try

FTE = CALCULATE(

SUM(Table1[Full Time Equivalent]),

FILTER(Table 4, Table 4[Date] = MAX('Table 2'[Date Key]))

)

Thanks

Joe

Thanks @JoeBarry Unfortunately it's not filtering.
