• What is the cause and solution for SAP error message SPRX161 - WSDL cannot be converted in doc style; namespace is not unique ?

  The SAP error message SPRX161 indicates that there is an issue with the Web Service Description Language (WSDL) file being used in your SAP system. Specifically, the error states that the WSDL cannot be converted to document style because the namespace is not unique. This typically occurs when there are multiple definitions in the WSDL that share the same namespace, which can lead to ambiguity in the service definitions.
  Cause:
  
  Non-Unique Namespace: The WSDL file contains multiple elements or types that are defined under the same namespace, which is not allowed in document-style WSDLs.
  WSDL Structure: The structure of the WSDL may not conform to the expected standards, leading to conflicts in the namespace definitions.
  Service Definitions: If the WSDL is generated from multiple sources or if it combines different services, it may inadvertently create overlapping namespaces.
  
  Solution:
  To resolve the SPRX161 error, you can take the following steps:
  
  
  Review the WSDL: Open the WSDL file and check for any duplicate namespace declarations. Ensure that each service, type, and element has a unique namespace.
  
  
  Modify the WSDL: If you find duplicate namespaces, modify the WSDL to ensure that each namespace is unique. This may involve changing the target namespace or restructuring the WSDL.
  
  
  Regenerate the WSDL: If the WSDL is generated from a tool or service, consider regenerating it with the correct settings to avoid namespace conflicts.
  
  
  Test the WSDL: After making changes, test the WSDL to ensure that it can be successfully converted to document style without errors.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for specific guidelines on WSDL structure and best practices.
