If you receive the alert "The xxx field is required for this import"

If you receive the alert "The xxx field is required for this import," one or more of the records you're trying to import has no entry in the field you selected to identify the record.

To solve this issue, first, check the entry in the Identify xxx by field in the Import File window to be sure that setting is the correct one. If it is the correct setting, you must review the data you're trying to import; edit the data so that each record has an entry in the field you selected for identification.
