Getting error message when I added a column to my Excel source worksheet

[PlastiquesMoore]

Hi folks,

I'm pretty new to Power BI. I've created a dashboard in Power BI and I'm getting my data from an Excel worksheet. Everything goes well when I add rows of data in my Excel worksheet and then hit the "Refresh" button in Power BI. I get an error message when I add columns in my Excel worksheet when I hit the "Refresh" button in Power BI. Can someone help me please?

! The column 'Column48' of the table wasn't found.

Thanks

@PlastiquesMoore ,

You should click query editor and modify/add the column name in advanced editor when you modify/add columns in your data source.

I added my new columns in the middle of my Excel source worrksheet. I'll add the columns with the query editor, but does the order matter? Do both files have to be in the same column order?

Thanks!

Your error means that one of the steps in your query is looking for Column 48.  You will need to remove that reference to avoid the error.  Click each step until you find the first step with the error, and either edit the code in the formula bar to remove reference to it, or delete and replace that step.

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.

Regards,

Pat

But yes, when you add and remove columns it can be problematic. You need to edit your query and see where the error is occuring.

I created Tables and that solved part of my problem. Thanks!
