Creating a measure based on a fixed table and a fact table

I am trying to create a measure based on 2 tables (fixed data and dataset). The measure is the Daily Availability (number and/or percentage).

Table 1 has all the different Max availability for each terminal:

Terminal

Max GA

1

10

2

20

3

10

Table 2 has all the unique values of unavailability.

Date

Terminal

15/08/2019

1

15/08/2019

3

15/08/2019

1

15/08/2019

3

16/08/2019

1

18/08/2019

1

Table 1 and 2 has a relationship based on terminal.

For the visual I am using my date table that has a relationship with table 2 based on date.

When I test the calculation per day, the expression I used does not hold true when there are multiple entries of a specific terminal on a specific day.

My expression: GA= sumx(Table2,related(Table1Column2)-[Unavailable])

Date

Terminal

Max

Unavailable

GA

15/08/2019

1

10

15/08/2019

18/08/2019

which is not true because its suppose to be:

 Date

Terminal

Max

Unavailable

GA

15/08/2019

1

10

15/08/2019

16/08/2019

1

10

7

18/08/2019

1

10

2

8

So that when I filter on date first, I see the final GA per terminal. Please help.

Hi @Noah_Mom ,

 

At first, you need to create an index column in the Table 2.

Then create “value” , “count” , ”UnavailableAgg” columns in order.

value =
RANKX (
    FILTER (
        Table2,
        Table2[Terminal] = EARLIER ( Table2[Terminal] )
            && Table2[Date] = EARLIER ( Table2[Date] )
    ),
    Table2[Terminal],
    ,
)
Count =
CALCULATE (
    SUM ( 'Table2'[Value] ),
    FILTER (
        ALLEXCEPT ( 'Table2', 'Table2'[Terminal] ),
        'Table2'[Date] = EARLIER ( 'Table2'[Date] )
            && 'Table2'[Terminal] = EARLIER ( 'Table2'[Terminal] )
            && 'Table2'[index] <= EARLIER ( 'Table2'[index] )
    )
)
UnavailableAgg =
CALCULATE (
    SUM ( Table2[Unavailable] ),
    FILTER (
        Table2,
        Table2[Count] <= EARLIER ( Table2[Count] )
            && Table2[Terminal] = EARLIER ( Table2[Terminal] )
            && Table2[Date] = EARLIER ( Table2[Date] )
    )
)

Now, modify your measure “GA” and get the right visual.

GA =
SUMX ( Table2, RELATED ( Table1[Max GA] ) - Table2[UnavailableAgg] )
