• What is the cause and solution for SAP error message SRT_WSP452 - You cannot specify more than one interface name ?

  The SAP error message SRT_WSP452 indicates that there is an issue with the configuration of a web service in SAP, specifically that more than one interface name has been specified when only one is allowed. This error typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when dealing with web services.
  Cause:
  The error is caused by the configuration of a web service where multiple interface names have been defined in a way that is not supported. This can happen in various scenarios, such as:
  
  Incorrect Service Definition: The web service definition may have multiple interface names specified in the service configuration.
  Misconfiguration in the Service Consumer: The consumer of the web service may be incorrectly set up to call multiple interfaces instead of a single one.
  WSDL Issues: If the WSDL (Web Services Description Language) file used to define the web service has multiple interface definitions, it can lead to this error.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check Service Configuration:
  
  Go to the relevant service definition in the SAP system (Transaction code: SOAMANAGER).
  Ensure that only one interface name is specified for the web service. If multiple interfaces are listed, remove the unnecessary ones.
  
  
  
  Review WSDL:
  
  If you are using a WSDL file, check the WSDL for multiple interface definitions. Ensure that it defines only one interface for the service you are trying to use.
  
  
  
  Adjust Service Consumer:
  
  If you are consuming the web service, ensure that the consumer is configured to call the correct interface. Update the consumer configuration to point to the correct single interface.
  
  
  
  Regenerate Service:
  
  If changes were made to the service definition or WSDL, regenerate the service and re-deploy it to ensure that the changes take effect.
  
  
  
  Testing:
  
  After making the necessary changes, test the web service again to ensure that the error is resolved.
