On systems that allow overlapping MRNs, the HL7 Listener may log the following error upon receiving a message:
-
Merge Medical Record received without an Assigning Authority
This error may be logged when the Medical Records Chart message action encounters a merge message. The error indicates OnBase is configured to use assigning authorities to identify MRNs, but the incoming HL7 message did not contain an assigning authority value in the MRG segment.
If your system is configured for assigning authorities, ensure incoming HL7 messages specify an assigning authority for each MRN.
