• What is the cause and solution for SAP error message IDOC_ADAPTER251 - Only asynchronous processing supported for IDoc adapter outbound processg ?

  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.
  Cause:
  
  Synchronous vs. Asynchronous Processing: The IDoc adapter is designed to handle outbound IDocs in an asynchronous manner. If the configuration or the message flow is set up to expect synchronous processing, this error will occur.
  Incorrect Configuration: The integration flow or the receiver channel may be incorrectly configured to use synchronous communication instead of asynchronous.
  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).
  Ensure that the receiver channel for the IDoc is set to asynchronous processing.
  If you are using a message mapping or a process integration scenario, ensure that it is designed for asynchronous processing.
  
  
  
  Adjust Message Flow:
  
  If your scenario requires synchronous processing, consider redesigning the flow to accommodate asynchronous processing, as IDocs are inherently designed for asynchronous communication.
  
  
  
  Use Appropriate Message Types:
  
  Ensure that the message types being used are appropriate for asynchronous processing. If you need synchronous behavior, consider using other communication methods supported by SAP.
  
  
  
  Testing:
  
  After making the necessary changes, test the IDoc outbound processing to ensure that the error is resolved and that IDocs are being processed correctly.
  
  
  
  Related Information:
  
  IDoc Basics: IDocs (Intermediate Documents) are a standard SAP format for data interchange between SAP systems and external systems. They are typically used for asynchronous communication.
  SAP PI/PO Documentation: Refer to the official SAP documentation for more details on configuring IDoc adapters and understanding the differences between synchronous and asynchronous processing.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other users who may have encountered similar issues.
  
  By ensuring that your IDoc outbound processing is configured for asynchronous communication, you should be able to resolve the IDOC_ADAPTER251 error.
