Hi everyone there

I would be grateful if anyone could give me some guidance on the error below when trying to map Data Flow to create a new table:

Thank you very much

@malditoponi 

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

[malditoponi]

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

@malditoponi  did you ever get a response to this? I am having a similar issue 😞

[malditoponi]

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.

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

Thanks a lot, you saved my day 😉
