A new column in the source file isn't showing on my combined files data set.

I combine 2 CSV files from within a folder in power bi for my dataset. I have added a new column onto the end of each of these files but the new column does not appear within power bi. I have performed some transform data steps after adding the files together, is there a way to get the new column to show without undoing the transform data steps i have done?

Hi, thank you for the reply, i thought this also but it doesn't have that option, i'm not sure if it is becuase the files are combined:

Go to Transform Sample file, you can find this Columns= there.

Perfect Thank You!

Hi, when you click on Source, you will see Columns=5 or whichever number you first time imported. Afterwards, no matter how many columns you add to the source file, only that number in PBI will be read. Just delete it.
