This can happen during data transfer processes, such as when you are trying to load data from a source system to a target system.
  Cause:

  Adjust the Data Transfer Process:
  
  If the extraction structure is part of a data transfer process, ensure that the process is correctly configured to handle existing structures. This may involve modifying the data transfer settings or using a different extraction structure.
