Thanks so much...that was the issue. I was working with SharePoint List in Dataflow, and the SharePoint list table had the two columns just like you said....Id and ID. So I removed one of them and it resolved the issue

I solved this checking imported columns: One was column 'Id', another column 'ID' with the same values. Removing column 'ID' solved the error...

hi @msaenzpe I never got a reply but I've been told I was unable to use Dataflow due to licence permissions 😞 so I moved on to producing the data within powerapps.

Thank you @Mira_Ghaly
Yes this was checked before I posted. The table has only 7 rows with 2 attributes. No repetitions in any of them.

Thank you for your time.

Kind regards

@Anonymous

Can you check the attributes/columns on your entity/table as the error suggests there should be 2 attributes with the same name...
