  The SAP error message:
  WS_TOOL026 Type & already exists in the service definition
  
  Cause:
  This error occurs when you try to add or create a data type in a Web Service Definition (WSDL) that already exists in the service definition. Essentially, the system detects a duplicate type name within the same service definition, which is not allowed because each type must be unique to avoid conflicts in the generated WSDL and service metadata.
  When does it typically happen?
  
  When manually adding or importing types into a Web Service Definition in transaction SE80 or SOAMANAGER.
  When regenerating or extending a service and the system tries to create a type that is already present.
  When there is a naming conflict due to multiple includes or reused structures with the same name.
  
  
  Solution:
  
  
  Check for duplicates:
  
  Review the service definition to identify if the type name already exists.
  Use transaction SE80 or the Web Service Navigator to inspect the types defined in the service.
