• What is the cause and solution for SAP error message DS470 - Public and private lists may not be attached to a tree together ?

  The SAP error message DS470, which states "Public and private lists may not be attached to a tree together," typically occurs in the context of SAP's Data Services or Business Objects when dealing with data integration and management tasks. This error indicates that there is a conflict in the way lists (public and private) are being used in relation to a tree structure in your data flow or data model.
  Cause:
  The error arises when you attempt to attach both public and private lists to the same tree structure. In SAP Data Services, public lists are accessible to all users, while private lists are restricted to individual users. The system enforces this separation to maintain data integrity and security, hence the error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Your Lists: Check the lists you are trying to attach to the tree. Ensure that you are not mixing public and private lists in the same tree structure.
  
  
  Separate Lists: If you need to use both types of lists, consider creating separate trees for public and private lists. This way, you can maintain the integrity of each list type without causing conflicts.
  
  
  Modify List Types: If appropriate, you can change the type of the list you are using. For example, if a private list is not necessary, you can convert it to a public list, or vice versa, depending on your requirements.
  
  
  Check Data Flow: Ensure that your data flow or data model is designed correctly. Sometimes, restructuring the data flow can help avoid such conflicts.
  
  
  Consult Documentation: Refer to the SAP Data Services documentation for more detailed information on how to manage lists and trees effectively.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or your internal IT team for further assistance.
