Hi everyone,
I have a PBI report that gets updated every month. The PBI report extracts monthly Excel files through SharePoint.
It has been doing fine for more than 10 months now. However, recently a column name in the July Excel sheet has been changed from "Number of Late Penalties or Quality Points_1" to "Number of Late Penalty Points", and it has been agreed the PBI model needs to be updated to accommodate to the new column name: 'Number of Late Penalty Points'. Obviously, an error is expected upon refresh with the latest month update from July. PBI states that "The Column 'Number of Late Penalties or Quality Points_1' of the table wasn't found. Details: Number of Late Penalties or Quality Points_1." The error occurs when the file is being transformed.
The solution is to rename the column name to the new one, and hence I changed the name of the column to 'Number of Late Penalty Points' in PBI Power Query Editor on the Transform Sample File. However, it still gave me the same error. How do I resolve this issue? Does the PBI report reads old column name from old file and the new column name from Jul everytime it refreshes? Thank you.
Solved! Go to Solution.
i managed to figure out the solution.

I also would like to mention that there is a Sample File (an Excel file) uploaded onto Power Query Editor which has the old column name. Do I need to re-upload a new Sample File (Excel File) with the new column name?

Thank you for your response. I did review all the M language, but still it gives me the same error: "OLE DB or ODBC error: [Expression.Error] The column 'Number of Late Penalty or Quality Points_1' of the table wasn't found."
I realised the model uploaded all files, so it appears that it may read the old column names from past files and the new name from July file, therefore giving me this error? My first question is do the PBI report extract the July file only, or it extracts all files (old & new)?
