  The SAP error message /BOBF/CONF189 indicates an issue related to the Business Object Processing Framework (BOPF) in SAP. Specifically, it suggests that a node in a BOPF object is trying to use a buffer that is not recognized or does not exist. This can occur in scenarios where there are inconsistencies in the configuration of the BOPF object or when the application is trying to access a buffer that has not been defined.
  Cause:
  
  Missing Buffer Definition: The buffer referenced in the error message may not have been defined in the BOPF configuration.
  Incorrect Node Configuration: The node may be incorrectly configured to reference a buffer that does not exist or has been deleted.
