• What is the cause and solution for SAP error message SRT_WSP3279 - Interface with name "&1" and namespace "&2" is defined more than once ?

  The SAP error message SRT_WSP3279 indicates that there is a conflict in the definition of a web service interface. Specifically, it means that an interface with the specified name and namespace has been defined more than once in the system. This can lead to ambiguity when the system tries to resolve which interface to use.
  Cause:
  
  Duplicate Interface Definitions: The most common cause of this error is that the same web service interface has been defined multiple times, either in the same namespace or across different namespaces.
  Transport Issues: If you have transported objects from one system to another, it is possible that the same interface was included in multiple transports, leading to duplicates.
  Development Errors: During development, if multiple developers are working on the same interface without proper coordination, it can lead to duplicate definitions.
  
  Solution:
  
  
  Check for Duplicates: 
  
  Go to the SAP transaction code SOAMANAGER and navigate to the "Web Service Configuration" section.
  Search for the interface using the name and namespace provided in the error message.
  Identify if there are multiple entries for the same interface.
  
  
  
  Remove or Rename Duplicates: 
  
  If you find duplicate entries, you will need to either delete or rename the duplicate interface definitions to resolve the conflict.
  Ensure that you have a backup or that the duplicates are not being used before deletion.
  
  
  
  Transport Management: 
  
  If the issue arose due to transport, review the transport requests to ensure that the same interface is not being transported multiple times.
  Adjust the transport requests accordingly to avoid duplicates.
  
  
  
  Check Development Guidelines: 
  
  Implement guidelines for interface naming and development to prevent future occurrences of this issue.
  Encourage developers to check existing interfaces before creating new ones.
  
  
  
  System Consistency Check: 
  
  After making changes, perform a consistency check in the system to ensure that there are no remaining issues related to web service definitions.
