  The SAP error message /AIF/ENGINE_IDOC012 indicates that there is a configuration issue in the Application Interface Framework (AIF) where more than one interface is assigned to a specific combination of basic type and message type for IDocs. This can lead to ambiguity in processing, as the system does not know which interface to use for the given IDoc.
  Cause:
  The primary cause of this error is that multiple interfaces have been defined in the AIF for the same basic type and message type combination. This can happen due to:
  
  Duplicate Configuration: Multiple interfaces might have been created unintentionally for the same IDoc type.
  Incorrect Mapping: The mapping of IDoc types to interfaces may not have been set up correctly.
  Changes in Configuration: Changes made to the AIF configuration without proper checks can lead to this issue.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Interface Assignments:

  Review the purpose of each interface to determine which one should remain.
  
  
  
  Remove or Adjust Duplicates:
  
  If you find multiple interfaces assigned, decide which one to keep based on your business requirements.
  Remove or deactivate the unnecessary interfaces to eliminate the conflict.
  
  
  
  Test the Configuration:
  
  After making changes, test the IDoc processing to ensure that the error no longer occurs and that the correct interface is being used.
  
  
  
  Documentation:
