I have a question around importing deals. We are trying to clean up our deal list so we exported to Excel to remove all the outdated deals and now I am trying to reimport the new deals (I copied to a new Excel sheet). I keep getting an error message saying that some fields are missing a header row (none are missing). Apparently some fields are read-only and cannot be imported. To save me doing a trial and error on every single column, does anyone know which deal fields CANNOT be imported. I thought the import would be straightforward but that is very much not the case with deal imports. Any assistance would be greatly appreciated. Thank you.
