When Piper flags a row, the field on the ImportValidationIssue tells you exactly which column or mapped field is at fault — for example, "analyteId", "resultValue", or "sampleDate". Together with the value field showing what the bad data actually was and the message explaining why it is invalid, the field name lets compliance reviewers quickly locate and understand the problem. For recurring issues on the same field across many rows, it often signals that the ImportMappingProfile's columnMapping needs adjustment for that column.
