• What is the cause and solution for SAP error message SWF_XI_ADAPTER056 - Only synchronous update mode is supported ?

  The SAP error message SWF_XI_ADAPTER056: Only synchronous update mode is supported typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when there is an issue with the configuration of the integration scenario, particularly when dealing with synchronous communication.
  Cause:
  This error generally arises due to the following reasons:
  
  
  Asynchronous vs. Synchronous Communication: The error indicates that the system is trying to process a message in an asynchronous manner, but the configuration or the receiver system only supports synchronous processing. This can happen if the sender is configured to send messages asynchronously while the receiver expects synchronous communication.
  
  
  Incorrect Configuration: The integration flow (iFlow) or the receiver channel may be incorrectly configured to handle synchronous requests. This can include settings in the integration scenario that do not match the expected behavior of the involved systems.
  
  
  Service Interface Mismatch: The service interface defined in the Enterprise Services Repository (ESR) may not align with the expected interface in the receiver system, leading to a mismatch in processing modes.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Communication Mode: Verify the communication mode of both the sender and receiver systems. Ensure that if the sender is set to send messages synchronously, the receiver is also configured to accept synchronous messages.
  
  
  Review iFlow Configuration: Inspect the iFlow in the Integration Directory. Ensure that the sender and receiver channels are correctly set up for synchronous communication. Look for any settings that might indicate asynchronous processing.
  
  
  Adjust Receiver Settings: If the receiver system is not capable of handling synchronous requests, consider changing the sender configuration to use asynchronous communication instead, if that is acceptable for your business process.
  
  
  Service Interface Validation: Check the service interfaces in the ESR to ensure they are correctly defined and that the expected message types align with the actual messages being sent.
  
  
  Testing: After making the necessary adjustments, perform tests to ensure that the communication works as expected without triggering the error.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for Process Integration and Process Orchestration for detailed guidance on configuring synchronous and asynchronous communication.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other users who may have encountered similar issues.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SXMB_MONI for monitoring messages and SXI_MONITOR for checking integration scenarios.
  
  By following these steps, you should be able to identify the root cause of the error and implement the necessary changes to resolve it.
