Filters and data tables

[samucaeq]

I have three data tables with some common columns, mainly descriptive fields.
The other columns have fields with numeric values.
Each table contains data of a particular parameter of a unit.
I did not build the tables, I just want to use them to analise some key aspects.
I want to create a report with three data matrix, each one for a specific parameter, but, for easyness of use, I want to have just one set of filters (the common columns).
How can I set define the relation between the tables' columns? I mean, how can I inform to the system that Column 1 of Table 1 corresponds to Column 2 of Table 2 and column 1 from Table 3, for instance? Is it necessary to declare such relations or are there a better way to build these filtering strategy?

Hi @samucaeq,

To filter multiple table visuals via a single slicer, you should create corresponding relationships between these tables based on common fields. Please see this article: Create and manage relationships in Power BI Desktop

If you still have any question about relationship configuration, please illustrate your requirement or issue with sample data. I need to know your table structure.

Hi @samucaeq

I think you're looking for a separated table. For example, you have three tables with sales and customer by territories (UsaSales, EuropeSales and AsiaSales). Then, you can create a new table only for Customers taken from each table.

Customer = 

DISTINCT
(
	UNION
	(
	    SELECTCOLUMNS(AsiaSales;"CustomerID";AsiaSales[CustomerID]);    
            SELECTCOLUMNS(EuropeSales;"CustomerID";EuropeSales[CustomerID]);
            SELECTCOLUMNS(USASales;"CustomerID";USASales[CustomerID])
	)
) 

NOTE: You need to create the relationonship between the four tables.

Now, you're able to filter the three tables by The Customer one.

I hope this helps

I don't really understand the question.
Are you having trouble creating relationships within Power BI?
