• What is the cause and solution for SAP error message B1412 - Segment type & not defined for message type & ?

  The SAP error message B1412 ("Segment type & not defined for message type &") typically occurs in the context of Electronic Data Interchange (EDI) or Intermediate Document (IDoc) processing. This error indicates that the system is trying to process a segment that has not been defined for the specified message type in the IDoc configuration.
  Cause:
  
  Missing Segment Definition: The segment type specified in the error message is not defined in the IDoc type associated with the message type.
  Incorrect Configuration: There may be a misconfiguration in the IDoc type or message type settings.

  Solution:
  
  
  Check IDoc Type Configuration:
  
  Go to transaction code WE30 (IDoc Types) and verify that the segment type is defined for the specified message type.

  Consult Documentation:
  
  Review SAP documentation or notes related to the specific message type and segment type for any additional configuration steps or requirements.
