Hi  @MaPol 

I don't quite understand your question. Are you using dataset as a data source in Desktop and then getting this error when you get the data? Have you ever had a problem like this before? What is your Desktop version ?

Hi @Anonymous ,

Yes I'm creating a report and I tryed to add also this dataset as datasource. I also used other dataset as datasource in this report.

It's the first time I have this error, I was not using the last version but the problem persist also after updating to the last version.

Best regarsds,

Matteo

In my case, I just found one of the freshly added measures via Tabular Editor that was breaking the update. Removed it from the report. Added it again with a different name and everything worked.

Finding that measure was a matter of successively deleting measures until the update worked.

Also from the recommendations I've seen:

Check for Duplicate Elements: Ensure that the data or elements you are querying do not contain duplicates when they are not supposed to. This is often the case when you expect a unique identifier but find multiple entries with the same identifier.
