• What is the cause and solution for SAP error message B1110 - Reference message type may not have reference ?

  The SAP error message B1110, which states "Reference message type may not have reference," typically occurs in the context of message type configuration in the SAP system, particularly when dealing with IDoc (Intermediate Document) processing or other message types in the SAP Application Interface Framework (AIF).
  Cause:
  This error usually arises when there is an inconsistency in the configuration of message types. Specifically, it indicates that a message type is incorrectly set up to reference another message type that is not allowed to be referenced. This can happen due to:
  
  Incorrect Configuration: The message type being referenced may not be configured to allow references, or it may not exist.
  Hierarchy Issues: The message type hierarchy may be incorrectly defined, leading to a situation where a message type is trying to reference another type that is not valid.
  Data Model Issues: There may be issues with the underlying data model that prevent the reference from being valid.
  
  Solution:
  To resolve the B1110 error, you can take the following steps:
  
  
  Check Message Type Configuration:
  
  Go to transaction code WE30 (for IDoc types) or WE81 (for message types) and review the configuration of the message types involved.
  Ensure that the message type you are trying to reference is correctly defined and that it is allowed to be referenced by the other message type.
  
  
  
  Review the Reference Settings:
  
  Check the settings for the message type that is causing the error. Ensure that it is not set to be a reference message type if it should not be.
  If necessary, adjust the configuration to allow or disallow references as appropriate.
  
  
  
  Check for Consistency:
  
  Ensure that all related message types and IDoc types are consistent and correctly defined in the system.
  Look for any discrepancies in the configuration that might lead to this error.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to message types and IDoc processing for any specific guidelines or known issues.
  
  
  
  Testing:
  
  After making changes, test the configuration to ensure that the error no longer occurs and that the message processing works as expected.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as WE30 (IDoc Types), WE81 (Message Types), and WE20 (Partner Profiles) for managing IDoc and message type configurations.
  SAP Notes: Check SAP Notes for any updates or patches that may address known issues related to message types and IDocs.
  Community Forums: Engage with SAP community forums or support channels for additional insights or similar cases encountered by other users.
