Visual Legend - Repeated indices found in GroupBy or Projections

Today after preparing the base model (dimensional) for the data, i set out to explore it a bit.

 

All worked fine, until suddently whilst adding legends to my graphs, I always get this error when using information from the fact table: "Couldn't load the data for this visual. Repeated indices found in GroupBy or Projections".

 

The error isn't exactly explicit, but I assume this might be related with the fact that I'm appending multiple CVS together; from which I then build the facts and dimensions directly on PBI, and the indices are somehow messed up.

Has anyone had this problem before?

Dear v-lionel-msft,

I apologize for the late reply. Oddly the enough, the problem seems to have fixed itself. What seems to have triggered the correction was the use of DAX Studio to export the tables one by one. I'm assuming this was a memory key allocation conflict by PowerBI from using multiple append queries, but I can only assume.

Once again, thank you for your help.

Ran into the same error here and fixed it by removing the conditional color before applying the legend. I think the reason for this case is that, some conditional colors have already been applied, and adding a legend column will triggers another usage on multiple colors. Then there's conflict on the color applying rules, and Powerbi just couldn't determine which rule to use for the colors. To solve such confict, you could just give up on either the legend or the conditionale color.

100%  @DanT this is the solution.

Hi,

 

Have a similar issue when for the given table:

 

DateCategoryCol 1Col 2
1/1/2020             112321
1/1/2020             214332
1/1/2020             312312
1/2/2020             123432
1/2/2020             243243


where I calculated the measure X=Divide (sum(Col 1), sum(Col 2)).

When I drag the column Category to the 'legend' box of a line chart (with date as 'axis' and X as 'values') I get the error message "Repeated indices found in GroupBy or Projections"

 

Thanks for your help

Hi @GuilhermeB ,

 

The problem is that there is a grouping and aggregation conflict between the fields of X axis and the Legend.

Please show me the sample data model, I will check it for you.
