Error when editing column names in Advanced Query Editor
Two columns were added to the source table which have the same names that columns already loaded were changed to. So I went into the Advanced editor and changed the names of the already loaded column...

I don't see any issues with the M code no that you have suffixed the names with "old".
I was in a similar situation and I did create a new connection to the file and on the new connection I replaced the M code shared by you.
Can you give it a try If it doesn't work you have to give the file used in it with only one row and you can replace all the values in that row with test data.
Anonymous I modified that step by changing the new names to something other than the column names being added. So then in the preview it had both the new columns and the old columns, which is what I am looking for. But then when I close and apply I get that error.
Hi Anonymous
Can you send me the file or the M Code for the same.
