Hi,
I have a very basic question, I have a list of data each month and I want to look at the permanent file to see if each vendor should be audited or not. I also want the final output to flag if a vendor is new and not in the permanent file. I know how to join the data but lose the Simba line when joining the data (and not sure how to flag it is new).
I've attached the excel workbook for reference.
The new data each month
