Power BI - Get value from a different table

Hi Community,


I was wondering if it is possible to do the following:

I have two tables in PowerBI, one called "Project Overview" and another called "Project X".

In the "Project Overview" table I want to create a custom column, called "Project start date", and that information is in a column inside the table "Project X".

Also, there is a column called "Project Name" in the table "Project Overview" with the name of that table with details about the project. In this example, the value in that column is "Project X".


At the moment I can get that information by using:

#"Project X"[Start Date]{0}


However, I can have mutiple projects in the table "Project overview" and I wanted to get that value dynamically.


Is there a way to archive that? Basically get the value from column "Project Name" and then look for a table with the same name and get the value in column "Start Date"?


Thank you all in advance.

Hi @r_user ,

What is your data source? If it's an Excel workbook, you can filter out all the Project x tables in the Source step and append them as one table.


Create a new blank query --> paste the m-code of Source step --> Filter the Name column and expand columns and remove the unwanted columns --> result.




At this point, you can use the merge query to get the start date of each project.




If this is not the case, and each Project table has project information only in the table name, you will have to consider adding a custom column for the project name and then repeat the above steps.

@r_user , with the description, seems like you can have 1 to Many join between project X and Project overview


If you can have one to many join


then you can have a new column in DAX in project overview


related('Project X'[Start Date])


For any type of join


maxX(filter('Project X', 'project Overview'[project name]= 'Project X'[project name] ), 'Project X'[Start Date])
