Calculate average by group ignoring certain filter

[Anonymous]

Hello,

my data looks like the following

Date                 Emloyee      Group        Task         Duration

2020-01-01       A                 1                aa            2

2020-01-01       A                 1                aa            4

2020-01-01       A                 1                bb           8

2020-01-01       B                  1               aa            4

2020-01-01       B                  1               bb            3

2020-01-01       B                  1               bb           11

2020-01-01       C                  2               cc           3

2020-01-01       C                  2               cc           3

2020-01-01       D                  2              cc            4

2020-01-01       D                  2              cc            4

2020-01-02       A                 1                aa            2 

2020-01-02       A                 1                aa            2

2020-01-02       A                 1                bb           3

2020-01-02       B                  1               aa           5

2020-01-02       B                  1               bb           2

2020-01-02       B                  1               bb           4

2020-01-02       C                  2               cc            6

2020-01-02       C                  2               cc            4

2020-01-02       D                  2              cc            2

2020-01-02       D                  2              cc            6

.                        .                   .                 .              .

.                        .                   .                 .              .

.                        .                   .                 .              .

My aim is to calculate the average duaration for every employee and every task and compare them across their group.

So for example Employee A completed Task aa in 2,5 Minutes ((2+4+2+2)/4 = 2,5) on average whereas the average time for the whole group for this task was 3,2 minutes ((2+4+4+2+2+5)/6 = 3,166).  I want to do this for all tasks and all groups.

I want to show only one employee ( which can be selecte via the filter pane) and the average duaration for every task he did in a certain period and the group average for every task. So I would display 2 minutes for task aa for employee A and 3,2 minutes for his group. The measure should ignore the employee filter on page level but not others like Date (I want to compare results across months) or group.

Thanks.

Hi, @Anonymous 

Based on my research, you may create two measures as below.

EmpAvg = 
var _emp = SELECTEDVALUE('Table'[Employee])
var _task = SELECTEDVALUE('Table'[Task])
return
CALCULATE(
    AVERAGE('Table'[Duration]),
    ALLEXCEPT('Table','Table'[Employee],'Table'[Task],'Table'[Date])
)

GroupAvg = 
var _emp = SELECTEDVALUE('Table'[Employee])
var _task = SELECTEDVALUE('Table'[Task])
return
CALCULATE(
    AVERAGE('Table'[Duration]),
    FILTER(
        ALLEXCEPT('Table','Table'[Task],'Table'[Date]),
        'Table'[Group] in 
        CALCULATETABLE(
            DISTINCT('Table'[Group]),
            FILTER(
                ALL('Table'),
                'Table'[Employee] =_emp
            )
        )
        
    )
)

Result:

Hi @v-alq-msft 

thanks for your answer!

I tried it, however, I forgot to mention that my data is in three different tables - one fact table with the tasks and their durations and two dimension tables (one for employees and one for dates). Due to this your mesaure GroupAvg doesn't work. How can I use your measure with multiple tables? Thanks!

@Anonymous ,

Refer this can help. You have to use all except and filters

Hi @Anonymous 

try this measure

Measure = 
CALCULATE(
    AVERAGE( 'Table'[Duration] ),
    ALLEXCEPT( 'Table', 'Table'[Task], 'Table'[Emloyee] ),
    ALLSELECTED( 'Table'[Emloyee] )
)
