• What is the cause and solution for SAP error message SRT_WSP994 - Proxy Definition '&1' and Service Def '&2' are compatible in local system ?

  The SAP error message SRT_WSP994 indicates that there is a compatibility issue between the proxy definition and the service definition in the local system. This error typically arises in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when working with web services.
  Cause:
  The error message suggests that the proxy definition (which is a representation of a web service in the SAP system) and the service definition (which is the actual web service endpoint) are not compatible. This can happen due to several reasons:
  
  Version Mismatch: The proxy definition and the service definition may be based on different versions of the WSDL (Web Services Description Language) file.
  Changes in Service Definition: If the service definition has been modified (e.g., changes in the structure, data types, or operations) after the proxy was generated, it may lead to incompatibility.
  Incorrect Configuration: There may be configuration issues in the service registry or the service consumer settings.
  Transport Issues: If the proxy was transported from one system to another, it may not have been properly updated or synchronized with the service definition.
  
  Solution:
  To resolve the SRT_WSP994 error, you can follow these steps:
  
  
  Check Versions: Ensure that the proxy definition and the service definition are based on the same version of the WSDL. If they are not, regenerate the proxy definition using the correct WSDL.
  
  
  Regenerate Proxy: If there have been changes to the service definition, regenerate the proxy in the SAP system. This can be done using transaction SPROXY:
  
  Navigate to the relevant proxy object.
  Right-click and select "Generate" to create a new proxy definition based on the current service definition.
  
  
  
  Review Configuration: Check the configuration settings in the Integration Directory (if using PI/PO) to ensure that the service is correctly defined and that the endpoint is reachable.
  
  
  Test Connectivity: Use transaction SOAMANAGER to test the web service and ensure that it is functioning correctly. This can help identify if the issue is with the service itself or the proxy.
  
  
  Check Logs: Review the application logs (transaction SLG1) for any additional error messages or warnings that may provide more context about the issue.
  
  
  Transport Issues: If the proxy was transported, ensure that all necessary objects were included in the transport request and that they were imported correctly in the target system.
