Regardless of what the view mandates the round-trip excel export will always contain an ID column as 1st column in the excel export. This contains the numeric unique id of the item being exported, which is then used to identify the target items when importing the data back. This ID column also contains a link pointing back to Codebeamer, and by clicking on that link will open the relate item in a web browser. This makes very easy to find the exported items from Excel later.
