  The SAP error message /AIF/RAL_MESSAGE018 indicates that there is an issue with the selection of interface versions in the Application Interface Framework (AIF). This error typically occurs when multiple versions of an interface are available, but the system requires that only one version be selected for processing.
  Cause:
  The error is caused by the following scenarios:
  
  Multiple Interface Versions: The interface you are trying to use has multiple versions defined in the AIF configuration, and the system cannot determine which one to use.
  Configuration Issues: There may be a misconfiguration in the AIF settings where multiple versions are active, but the system expects a single version to be selected for processing.
  Message Processing: When processing messages, if the system encounters multiple versions of the same interface, it raises this error to prevent ambiguity.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Interface Versions:
  
  Go to the AIF configuration and check the available versions for the interface in question.
  Ensure that only one version is active or that the correct version is selected for processing.

  You may need to deactivate or remove unnecessary versions if they are not needed.
  
  
  
  Message Mapping:
  
  Review the message mapping settings to ensure that the correct interface version is being referenced in the mapping logic.
  
  
  
  Testing:
  
  After making changes, test the interface to ensure that the error no longer occurs and that the correct version is being processed.
