• Message text: Proxy generation terminated: not supported

INCLUDE SPRX_GET_WSDL OBJECT DOKU ID TX

What causes this issue?

You used the language command <redefine> in the interface description.
This command completely redefines existing types. Schema definitions
with the <redefine> extension, however, use the original type
definition.
Since a type can only have one status in ABAP, this feature is not
supported by the proxy generation.

System Response

The system produces a system error. The proxy cannot be generated.

How to fix this error?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message SPRX066 - Proxy generation terminated: not supported ?

  The SAP error message SPRX066 indicates that there is an issue with proxy generation, specifically that the <redefine> operation is not supported. This error typically occurs when you are trying to generate a proxy for a web service or an interface that has been defined in a way that is not compatible with the proxy generation process.
  Causes:
  
  Redefinition of Types: The error often arises when there are complex types or structures that have been redefined in the WSDL (Web Services Description Language) file. This can happen if the WSDL uses the <redefine> element to modify existing types.
  Unsupported Features: The SAP proxy generation tool may not support certain XML schema features, such as redefinitions, which can lead to this error.
  Version Mismatch: There may be a mismatch between the version of the WSDL and the version of the SAP system or the proxy generation tool being used.
  
  Solutions:
  
  Modify the WSDL: If you have control over the WSDL, consider removing the <redefine> elements or restructuring the WSDL to avoid the need for redefinitions. This may involve creating new types instead of redefining existing ones.
  Use a Different Tool: If modifying the WSDL is not feasible, consider using a different tool or method for generating the proxy that can handle redefinitions, if available.
  Check SAP Notes: Look for relevant SAP Notes that may address this specific issue. SAP frequently updates its documentation and provides fixes or workarounds for known issues.
  Consult Documentation: Review the SAP documentation for proxy generation to ensure that you are following the correct procedures and that your WSDL is compliant with the expected standards.
  Contact SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance. They may have additional insights or solutions based on your specific scenario.
  
  Related Information:
  
  Proxy Generation: This process involves creating a client-side representation of a web service that can be used in SAP systems to call the service.
  WSDL: A WSDL file describes the web service, including its operations, input and output parameters, and data types.
  SAP PI/PO: If you are using SAP Process Integration (PI) or Process Orchestration (PO), ensure that your configurations are correct and that you are using compatible versions of the software.
  
  By addressing the root cause of the <redefine> issue in the WSDL, you should be able to resolve the SPRX066 error and successfully generate the proxy.
