  SAP Error Message:
  WPRO_XI_PROXY033: Interface &1 in namespace &2 not found in the application system
  
  Cause:
  This error occurs when the SAP system tries to process or call a proxy interface that is not available or not registered in the target application system. Specifically, the interface (identified by name &1) within the given namespace (&2) does not exist or is not recognized in the system where the proxy call is being made.
  Common reasons include:
  
  The proxy interface has not been imported or generated in the target system.
  The namespace or interface name is incorrect or misspelled.
  The system landscape or configuration is inconsistent, and the interface is missing in the application system.
  Transport or configuration issues where the interface was not transported properly.
  The software component or add-on containing the interface is not installed or activated.
  
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Check Interface Existence:
  
  Go to transaction SPROXY in the target system.
  Search for the interface name (&1) in the namespace (&2).
  Verify if the interface exists and is active.
  
  
  
  Import or Generate Proxy:
  
  If the interface is missing, import the relevant proxy objects or generate the proxy interface in SPROXY.
  You may need to import the corresponding software component or add-on that contains the interface.
  
  
  
  Check Namespace and Interface Name:
  
  Confirm that the namespace and interface name used in the proxy call are correct.
  Check the configuration or code that triggers the proxy call for typos or incorrect values.
  
  
  
  Transport and System Landscape:
  
  Verify that the interface has been transported correctly from the development system to the target system.
  Check transport logs and ensure no errors occurred during import.
  
  
  
  Check Software Component Installation:
  
  Ensure that the software component or add-on containing the interface is installed and active in the target system.
  
  
  
  Re-import or Re-generate Proxy Objects:
  
  Sometimes re-importing or regenerating proxy objects in SPROXY can resolve inconsistencies.
  
  
  
  Check Integration Directory / ESR (if PI/PO involved):
  
  If the interface is part of SAP PI/PO integration, verify that the interface is correctly defined and deployed in the ESR and Integration Directory.
  
  
  
  
  Related Information:

  Summary:
  The error WPRO_XI_PROXY033 indicates that the proxy interface being called is not found in the target system. The solution involves verifying the existence of the interface in SPROXY, ensuring correct namespace and interface names, importing or generating the proxy if missing, and checking transport and system configuration.
