How to get values for relationship between 3 tables

[james_andrade]

The Comparison Table

Project_ID	Project_Plan_ID
Project_A_2021	Project_Plan_A_2020
Project_A_2021	Project_Plan_A_2021
Project_B_2021	Project_Plan_B_2020
Project_B_2021	Project_Plan_B_2021

From this table the user will select 1 Project and 1 Project_Plan to compare it to

The Project Table

Project_ID	Activity Name	Actual
Project_A_2021	Pick Apples	1
Project_A_2021	Pick Oranges	2
Project_B_2021	Pick Apples	3
Project_B_2021	Pick Oranges	4

The Project_Plan Table

Project_Plan_ID	Activity Name	Planned
Project_Plan_A_2021	Pick Apples	5
Project_Plan_A_2021	Pick Oranges	6
Project_Plan_A_2020	Pick Apples	7
Project_Plan_A_2020	Pick Oranges	8
Project_Plan_B_2021	Pick Apples	9
Project_Plan_B_2021	Pick Oranges	10
Project_Plan_B_2020	Pick Apples	11
Project_Plan_B_2020	Pick Oranges	12

Result I'm looking for:

Project filtered to: Project_B_2021

Project Plan filtered to: Project_Plan_B_2020

Output

Activity Name	Planned	Actual
Pick Apples	11	3
Pick Oranges	12	4

Note: I don't want to display output until the Project and Project Plan have not been selected

The joins in this relationship are:

'Project' table to 'Comparison' table using 'Project_ID'

'Project_Plan' table to 'Comparison' table using 'Project_Plan_ID'

'Project' table to 'Project_Plan' table using 'Activity_Name'

Can anyone tell me how to do this? Everything I've tried so far does not work.

Hi @james_andrade ,

Based on your description, you could do some steps as follows.

1. create a relationship between "The Project Table" and "The Project_Plan Table" and make it active

2. create two measures

Actual =
CALCULATE (
    MAX ( 'Project'[Actual] ),
    FILTER ( 'Project', [Project_ID] = SELECTEDVALUE ( Comparison[Project_ID] ) )
)

Planned =
CALCULATE (
    MAX ( 'Project_Plan'[Planned] ),
    FILTER (
        'Project_Plan',
        [Project_Plan_ID] = SELECTEDVALUE ( Comparison[Project_Plan_ID] )
    )
)

3. create a table visual.

Result:

Hope that's what you were looking for.

Hi @james_andrade ,

My test result is here.

Due to the one-to-many relationship between "Project_ID" and "Project_Plan_ID", this result will occur if only the relationships are established in three tables.

Do you just want to display the output?
