Regarding an RDC Import Error, why might it be necessary to append data instead of overlaying?

Appending data instead of overlaying is sometimes necessary when overlaying is restricted for existing productions. In a legally sensitive and highly regulated environment, existing productions must be preserved for audit and compliance reasons. This preservation can prevent the overlaying of data, which might risk losing original files or evidence that is crucial for legal cases or investigations.

When data is appended, it allows for the inclusion of new information without disturbing the integrity and continuity of already established records. This method ensures that all relevant data remains accessible and verifiable, which is essential in maintaining a reliable chain of custody for legal and compliance purposes.

Understanding the implications of how data is managed in a system is vital for ensuring that legal obligations are met, and users can effectively manage and retrieve necessary information without jeopardizing existing records.
