Why is a separate interface order needed for each AR?

Interfaces are configured on an AR basis – meaning the company, all directories/sub-directories and associated setup for the HIS functionality must be in place and then the interface configuration in Linux, in the software tables and in the Interface Management System (IMS) can be set up. Each company has an ARID and a FACID which drive the interface configuration as all HL7 messages must contain these identifiers to ensure the data in the message is routed appropriately. Interface setup/configuration/maintenance and support all starts with an order as we have to schedule and allocate the appropriate resources to make the interface work, as well as ensure documentation reflects what is set up and expected to be supported/managed with software updates and changes.
