  Missing Structure Definition: The specified receiver structure has not been created or activated in the system.
  Incorrect Configuration: There may be a misconfiguration in the data model or mapping that points to a non-existent structure.
  Transport Issues: If the structure was recently transported from another system, it may not have been successfully imported.
