Hi @Anonymous ,

 

Power BI sometimes automatically creates relationships between the queries used to drive the data in a report. When I have encountered this error or similar errors in the past, I.

1.Go to Manage Relationships
2.Verify that a relationship is listed
3.Evaluate the from and to relationships that are listed as active
4.Remove any invalid "from" and "to" relationships between independent data sets

 

The most common issue I have had in the past is that I will have two very different queries pulling data from different sources with similar column names and Power BI will create an invalid relationship between them. After removing that relationship, it always solved my problem.

 

If you want to avoid this issue next time, uncheck below settings in the option:

Hi @Anonymous, 

 

The error is saying that the JobTitleDimTbl has a Job Title column that contains the same value more than once.  Given that the Job Title column is a "primary key" and that a primary key should only have unique values (i.e. values that appear only once), it is returning a Data Source Error.

 

If you require the Job Title column to have the same value appear more than once, I would recommend changing the duplicate to include a 1 or 2 at the end of the Job Title.  For example, if your duplicate is Job Title = "Chief Executive Officer" and you need two specific roles with this title, you can change these to Chief Executive Officer 1 and Chief Executive Officer 2.  

 

Alternatively, if the Job Titles are unique and only one value for each Job Title should exist, then you can:

  1. Go to Power Query
  2. Click on the column Job Title in the JobTitleDimTbl query.
  3. Right click, and click on "Remove Duplicates"

Hope this helps 🙂

Hi @Anonymous,

 

The error that you presented implied "Yard Controller" was listed twice.  If it's not there, it may have to do with the "-" which is in the list. Is there a reason you have or need that in the list?

 

Thanks,

Theo
