• What is the cause and solution for SAP error message B1012 - Message type & does not exist ?

  The SAP error message B1012, which states "Message type & does not exist," typically occurs in the context of SAP's IDoc (Intermediate Document) processing. This error indicates that the system is trying to use a message type that has not been defined or is not available in the system.
  Cause:
  
  Missing Message Type: The specified message type is not defined in the system. This could happen if the message type was never created or if it was deleted.
  Incorrect Configuration: The configuration settings for the IDoc processing may be incorrect, leading to the system looking for a message type that does not exist.
  Transport Issues: If the message type was recently transported from another system, there may have been issues during the transport process that caused it not to be created properly.
  Typographical Error: There may be a typo in the message type name being referenced in the program or configuration.
  
  Solution:
  
  
  Check Message Type Definition:
  
  Go to transaction code WE30 (IDoc Types) or WE81 (Message Types) to verify if the message type exists.
  If it does not exist, you may need to create it or ensure that it is properly defined.
  
  
  
  Create or Adjust Message Type:
  
  If the message type is missing, you can create it using transaction WE81.
  Ensure that the message type is correctly linked to the appropriate IDoc type.
  
  
  
  Review Configuration:
  
  Check the configuration settings in transaction WE20 (Partner Profiles) to ensure that the message type is correctly assigned to the relevant partner profiles.
  Verify that the settings for the outbound and inbound parameters are correct.
  
  
  
  Check for Transport Issues:
  
  If the message type was recently transported, check the transport logs for any errors or issues.
  You may need to re-transport the message type or manually create it in the target system.
  
  
  
  Correct Typographical Errors:
  
  Review the code or configuration where the message type is referenced to ensure there are no typos or incorrect references.
