Receiving an EDI transaction and passing it through the communications interface stage usually requires:

A. translating and unbundling transactions.

B. routing verification procedures.

C. passing data to the appropriate application system.

D. creating a point of receipt audit log.

Explanation:

The communication-s interface stage requires routing verification procedures. Edi or ANSI X12 is a standard that must be interpreted by an application for transactions to be processed and then to be invoiced, paid and sent, whether they are for merchandise or services. There is no point sending and receiving EDI transactions if they cannot be processed by an internal system.

Unpacking transactions and recording audit logs are important elements that help follow business rules and establish controls, but are not part of the communications interface stage.
