Hi @Asmaa-elsheikh 


Which kind of data source are you connecting to? Do you mean someone may add columns to the table ( which you are querying from ) at the data source side? 


If this issue happens after the "Source" step, and you are sure about which columns are needed in your report and you don't need any newly added columns, you can add a step after the "Source" step to select the specific columns by name. Sometimes this will work to resolve this issue. 


You can also try the method suggested by Nate.

Actually, somtimes I need these new columns, so what is the best solution?
And if I deleted a column or edit it's name, still gives me an error, should I edit it in the query, so I avoid the errors ?


Power Query can handle appended columns in some circumstances. It will most certainly freak out about inserted columns, and in the service it will error out every time.  Refactor your process.

Wherever the step with the error is, try adding ExtraValues.Ignore as the final parameter to the Table Function in that step.



I’m usually answering from my phone, which means the results are visualized only in my mind. You’ll need to use my answer to know that it works—but it will work!!
