    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 everyone, 

i'm new here. i'm not sure whether we can fix this. I used excel data which has a lots of columns in Date Columns , I import into Power BI and then choose Unpivot other columns to be in a row, It works good. but after that i turn to Excel file and delete one of the date columns and then refresh in PBI , it said the Column Number 15 not found. Is there any way i can settle this ? Delete and add data in Excel and refresh the data in PBI to be okay. 
seems like i can;t remove the data in Excel only to add more. 

Thanks with Best Regards,
