Hello,
I have 3 .txt files ( | separator) that are the source of my PowerBI dashboard. These 3 files are symmetric and have, let's say, 20 columns each. I usually use de combine and load options. Now I have 23 columns in the source files and I want to add these columns to power bi. It seems Power BI only looks for and brings the columns already imported in the past, but not the 3 new ones. How can I import to Power BI these 3 additional columns?
Thank you!
