How is an attachment control number (ACN) configured?

How is an attachment control number (ACN) configured?

• A. By editing a global system setting called ACNConfig
• B. By creating a new ACN record in the attachment index
• C. By duplicating a standard extension 70551 and modifying the ACN format parameter
• D. By selecting a dedicated ACN template in the portal

Answer: (C)

Attachment control numbers are defined through an Epic extension that specifies how the ACN is generated. The way to configure it is to duplicate the standard extension that already defines an ACN format (the one labeled with 70551) and modify its ACN format parameter. This approach preserves the original, keeps changes isolated, and lets you tailor the format (such as prefixes, date components, and a running sequence) to your needs without affecting other parts of the system. Edits to a global setting aren’t used for ACN formatting, creating a new ACN record in the attachment index isn’t the configuration mechanism, and selecting an ACN template in the portal isn’t how the ACN format is defined.
