This error indicates that there is an attempt to create a port (which is a communication endpoint) that already exists in the system.
  Cause:
  
  Duplicate Port Creation: The most common cause of this error is that there is an attempt to create a port with the same name and type that already exists in the system. This can happen during configuration or data migration processes.
  Configuration Issues: There may be issues in the configuration settings where the same port is being defined multiple times.
  Data Migration: If you are migrating data from one system to another, it is possible that the migration process is trying to create ports that already exist in the target system.
  
  Solution:
  
  
  Check Existing Ports: 
  
  Go to the relevant transaction or configuration area in SAP where ports are defined (e.g., transaction code SPRO for configuration).
  Check the list of existing ports to see if the port you are trying to create already exists.
  
  
  
  Modify or Delete Existing Port:
  
  If the port already exists and is not needed, consider deleting it or modifying it as per your requirements.
  If the port is needed, you may need to adjust your configuration to avoid the duplication.
  
  
  
  Adjust Migration Logic:
  
  If this error occurs during a data migration process, review the migration logic to ensure that it does not attempt to create ports that already exist in the target system.
