• Message type: E = Error

• Message class: SIW - Service Implementation Workbench

• Message number: 332

• Message text: Proxy has not yet been generated or proxy class is not active

What causes this issue?

SIW tries to retrieve additional information about service proxies in
order to process a request. The information available however does not
point to a valid proxy. This may either mean that the proxy you
requested has not been generated or activated or it can mean that the
values available do not point to a valid proxy anyway.
An example for the latter is that you specified "Outbound" for the
direction of the proxy although the proxy in question is an inbound one.

System Response

No information can be retrieved and the process stops.

How to fix this error?

generated and activated. If this is the case please double check if all
given values are valid.

• What is the cause and solution for SAP error message SIW332 - Proxy has not yet been generated or proxy class is not active ?

  The SAP error message SIW332 indicates that a proxy has not yet been generated or that the proxy class is not active. This error typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when working with web services or when trying to call a proxy object.
  Causes:
  
  Proxy Not Generated: The proxy class for the web service has not been generated in the SAP system. This can happen if the service definition has been created but the corresponding proxy has not been generated.
  Inactive Proxy Class: The proxy class exists but is not active. This can occur if the class has been deactivated or if there are issues with the transport of the proxy.
  Configuration Issues: There may be configuration issues in the Integration Directory or in the Service Registry that prevent the proxy from being recognized.
  Transport Issues: If the proxy was transported from one system to another, it may not have been activated in the target system.
  
  Solutions:
  
  
  Generate the Proxy:
  
  Go to the transaction SPROXY in the SAP GUI.
  Find the relevant service interface and generate the proxy class if it has not been generated yet.
  Ensure that you are in the correct namespace and that the service interface is properly defined.
  
  
  
  Activate the Proxy Class:
  
  In the same transaction SPROXY, check if the proxy class is active.
  If it is inactive, activate it by selecting the proxy and choosing the activation option.
  
  
  
  Check Configuration:
  
  Verify the configuration in the Integration Directory to ensure that the service is correctly defined and that the communication channel is set up properly.
  Check the Service Registry to ensure that the service is registered and accessible.
  
  
  
  Transport the Proxy:
  
  If the proxy was transported, ensure that the transport request was successfully imported into the target system.
  After importing, check if the proxy is active in the target system.
  
  
  
  Check for Errors in Logs:
  
  Review the application logs (transaction SLG1) for any related error messages that might provide more context on the issue.
  Check the system logs (transaction SM21) for any system-related issues that might affect the proxy.
