Why would you set Choice Action to Ignore on a transform field map?

Setting the Choice Action to “Ignore” on a transform field map in ServiceNow is used to avoid inserting dummy referenced records into the global domain. When importing data, if the system encounters a reference field value that does not match any existing records, setting the Choice Action to “Ignore” will prevent the creation of a new, potentially incorrect record. Instead, the system will skip the field and leave it blank, ensuring data integrity and avoiding the clutter of unnecessary records.
