Slice by year from 2 separate tables with independent date columns

Hello,

 

I have a dashboard created in Power BI Desktop and I am trying to filter by year for dates coming from date columns coming intwo separate tables.

 

E.g. I have a table for internal services and a table for external services and each service has a related date and metrics. I want to be able to slice my report based on year from both tables. I tried to build a relationship between these columns but get the error:

"You can't create a relationship between these two columns because one of the columns must have unique values."

 

How do I:

(a) Build a realtionship between these columns, or

(b) Merge the two columns into a 3rd separate date table column that will let me slice for my report?

In this scenario, you can create a calendar table as @Vvelarde mentioned. And you can also add a service type column for each table and then merge these two tables. Please refer to following steps.

 

  1. In Query Editor, select ‘Internal Services’ table to add a custom column. Do the same for ‘External Services’ table.

  2. Select ‘Internal Services’ table and click “Append Queries”.

  3. Drag ‘Internal Services[Date]’ into Field of Slicer.

hi @cm0215

 

You need a calendar table.

 

You can create quickly with New Table - Calendar("InitDate";"FinalDate") Example: Calendar("01/01/2016"; "31/03/2016")

 

Then you make the relationship with this table and your date columns
