When applying a filter on a related record in the message companion, you notice that...

The Message Companion relies on a successful link between a message and a specific record (like a Patient or Encounter). If a message encounters a failure error during processing (e.g., a critical identification error), Bridges may be unable to definitively link that message to the patient record in Chronicles. Because the link is missing, the message will not appear in tools like the Message Companion that filter specifically by that patient ' s ID.
