This error usually arises when the system is trying to send or receive messages via a proxy, but it cannot find the necessary logical port configuration.
  Cause:
  
  Missing Logical Port: The logical port for the specified proxy class has not been created or is missing.
  Incorrect Configuration: The logical port may exist but is not correctly configured.
  Transport Issues: If the system has recently undergone a transport, the logical port configuration may not have been transported correctly.
  Namespace Issues: The proxy class may be in a different namespace, and the logical port is not defined for that namespace.
  
  Solution:
  
  
  Create or Check Logical Port:
  
  Go to transaction SOAMANAGER.
  Navigate to the "Web Service Configuration" section.
  Look for the proxy class mentioned in the error message.

  If necessary, manually create the logical port in the target system.
  
  
  
  Namespace Verification:
  
  Verify that the proxy class and logical port are in the same namespace. If they are not, you may need to create a logical port in the correct namespace.
  
  
  
  Authorization Check:
  
  Ensure that the user has the necessary authorizations to access the logical port and the proxy class.
