Is it true that a mass update for an award must be saved before adding an attachment?

The statement is true. In the context of a mass update for an award, it's necessary to save the changes made during the update process before you can attach any documents or files. This requirement is often set to ensure data integrity, as it establishes a saved state of the award data that the attachment can reference. It prevents potential loss of data or inconsistencies, which could occur if an attachment were added without a secure save of the current state of the award. Saving first allows you to ensure that the updates made are finalized and accurately reflected before introducing additional elements like attachments.

The other choices do not align with common data management practices. For instance, the notion that attachments could be added before saving or in response to certain errors doesn't reflect the typical workflows where saving is prioritized to maintain data integrity and prevent confusion during the update process.
