  The SAP error message IDOC_ADAPTER251 indicates that there is an issue with the configuration of the IDoc adapter in the context of outbound processing. Specifically, it states that only asynchronous processing is supported for the IDoc adapter in outbound scenarios. This error typically arises when there is an attempt to use synchronous processing for an IDoc outbound message, which is not supported.

  Message Type: The message type being used may not be compatible with synchronous processing.
  
  
  Solution:
  
  
  Check Configuration:
  
  Review the configuration of the IDoc adapter in the Integration Directory (or PI/PO system).
