• What is the cause and solution for SAP error message B1806 - Message type & is dependent on itself ?

  The SAP error message B1806 ("Message type & is dependent on itself") typically occurs in the context of message control in SAP, particularly when dealing with output types in the Sales and Distribution (SD) module or other areas where message types are configured.
  Cause:
  This error indicates that there is a circular dependency in the configuration of message types. Specifically, it means that the message type you are trying to configure or use is set up in such a way that it references itself, which creates a logical inconsistency. This can happen if:
  
  The message type is incorrectly configured in the output determination procedure.
  There is a mistake in the assignment of the message type to the output condition records.
  The message type is set to trigger based on conditions that include itself.
  
  Solution:
  To resolve the B1806 error, you can follow these steps:
  
  
  Check Output Type Configuration:
  
  Go to the transaction code NACE (or SPRO for configuration).
  Navigate to the relevant application area (e.g., Sales and Distribution).
  Check the configuration for the message type that is causing the error.
  Ensure that the message type does not reference itself in any of its conditions or dependencies.
  
  
  
  Review Output Determination Procedure:
  
  In the output determination procedure, check the sequence of message types and ensure that there are no circular references.
  Make sure that the message type is not set to trigger based on conditions that include itself.
  
  
  
  Check Condition Records:
  
  Use transaction VV21 (or VV22, VV23 for changes and display) to check the condition records for the output type.
  Ensure that the condition records do not create a loop or dependency on the same message type.
  
  
  
  Test Changes:
  
  After making the necessary adjustments, test the output determination process to ensure that the error no longer occurs.
  
  
  
  Consult Documentation:
  
  If you are unsure about the configuration, refer to SAP documentation or consult with a functional consultant who specializes in the relevant module.
