Need help for data model
Hi Visharavana ,
As far as I know, Power BI Desktop allows only a single active relationship between two tables at a given time.
Currently, you want to create the relationship between PR, PO, GR and DimDate table.
From above sample relationship, we find that there are two active relationship between Date and PO.
DimDate -> PO
DimDate -> PR -> PO.
So Power BI will return error until you inactive one relationship.

Instead of having one dim_date table, create separate date tables for each of your tables (e.g., dim_date_PR, dim_date_PO, dim_date_GR). Each of these can have a many-to-one relationship with their respective tables based on their date columns.
Connect each date table to its corresponding table based on their respective date columns.
This approach avoids ambiguity and maintains clear relationships for each table.
If this helped, a Kudos 👍 or Solution mark would be great!

Thank you for your fast response.I want to use one date for the whole report. That's why I created dim_date. Your given idea does not fit this scenario because I want only one date column. That column filter used the whole report. Is there any other possible way?
