• What is the cause and solution for SAP error message SRT_WSP3035 - Domain system '&1' does not support communication type RFC ?

  The SAP error message SRT_WSP3035 indicates that the domain system specified (represented by &1) does not support the communication type RFC (Remote Function Call). This error typically arises in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when trying to establish communication between systems.
  Cause:
  
  Configuration Issues: The target system may not be configured to accept RFC calls. This could be due to incorrect settings in the SAP Gateway or the RFC destination.
  Communication Type Mismatch: The communication type specified in the configuration does not match the capabilities of the target system. For example, if the target system is set up for HTTP communication but the source system is trying to use RFC.
  Network Issues: There may be network connectivity issues preventing the systems from communicating properly.
  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations to perform the requested operation.
  
  Solution:
  
  
  Check Configuration:
  
  Verify the configuration of the RFC destination in transaction SM59. Ensure that the target system is correctly defined and that the communication type is set to RFC.
  Ensure that the target system is configured to accept RFC calls. This may involve checking the settings in the target system's profile or configuration.
  
  
  
  Adjust Communication Type:
  
  If the target system does not support RFC, consider changing the communication type in your configuration to one that is supported, such as HTTP or SOAP, depending on your integration scenario.
  
  
  
  Test Connectivity:
  
  Use the Connection Test feature in transaction SM59 to check if the RFC connection can be established successfully. This will help identify any connectivity issues.
  
  
  
  Check Authorizations:
  
  Ensure that the user credentials used for the RFC connection have the necessary authorizations to execute the required functions in the target system.
  
  
  
  Review Logs:
  
  Check the application logs (transaction SLG1) and the system logs (transaction SM21) for any additional error messages or warnings that could provide more context about the issue.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation for the specific version of your systems to ensure that all prerequisites and configurations are met for RFC communication.
