    Hi Chanleakna123,

     

    Since you have steps to transform Excel sheet columns, go to Query Editor and click Advanced Editor, you will see the Power Query explicitly mention column names. Whatever the old column is deleted or new column added, you need to modify the column names used in Power Query ( it can simply achieved by modify applied steps which you already done). I'm afraid this is unavoidable.

Hi Chanleakna123,

 

Have you opened Query Editor to check each step? 

 

 

As the column is deleted in source Excel file, you need to modify Power Query to get data. Please check each step from Source step listed in Applied Steps to ensure each step works fine.

    v-qiuyu-msft hi Dear , 
    I had fixed this by going to Query Editor > ( insert )Step between Promote Header and unpivot > refresh data > new data from excel comes in >Unpivot the columns again. Since i always have new columns added everyday. Do i need to repeat this everyday? Do we have any best practices on this ? 
    I'm sorry if i'm wrong , since i'm new here.
