Help with transformation
How can I make sure specific transformations such as remove top 3 rows and promote first row to header is applied to all source files when sourcing to a onedrive folder. I’ve successfully removed the top three rows by transforming the “Transform Sample File” but whenever I promote the top row to Column headers I get an error message stating “column 1” of the table wasn’t found.
This has been so frustrating. I can’t seem to get it to work. Any insight, tips, tricks, help ?
Hi Marza1991 ,
Try first removing the change type step each time you promoted the headers:then Remove changed type steps under other queries.
