  The SAP error message "53337 No message flow defined in ALE" typically occurs in the context of Application Link Enabling (ALE) when there is an issue with the configuration of the message flow between systems. This error indicates that the system is unable to find a defined message flow for the specific message type you are trying to process.
  Cause:
  
  Missing Configuration: The most common cause is that the message flow for the specific message type has not been defined in the ALE configuration.
