What must you do if an RDC Import Error shows that a document with a specific identifier already exists?

When faced with an RDC Import Error indicating that a document with a specific identifier already exists, the appropriate action is to overlay to overwrite the existing data. This approach allows the new data associated with that identifier to replace the previous entry, ensuring that the most current and accurate information is retained in the system.

Overlaying is particularly useful when updates or changes to the existing document are needed, and it maintains the identifier's integrity within the database. This method prevents duplication of records and enables efficient data management.

In this context, changing the identifier, deleting the existing document, or creating a new identifier would not resolve the issue effectively. Changing the identifier may lead to confusion or unintended consequences by misaligning data references. Deleting the existing document risks losing valuable information that might be necessary for historical or audit purposes. Creating a new identifier would simply add another layer of complexity and potentially lead to data inconsistency if the original document is still needed. Thus, overlaying is the most logical and efficient solution to properly handle this error within the system.
