When an ACK message is received, the Auto-Sender writes it to the log file. The ACK message is logged with the original message as an NTE segment (for example, "NTE|O| ACK RECEIVED- ").
The following ACK message characters are substituted in the NTE segment:
-
| is changed to !
-
^ is changed to #
-
~ is changed to @
These substitutions are necessary to prevent an HL7 parser (such as the HL7 EDI Processor) from interpreting the embedded ACK message as HL7 text.
