  If the PSP group is already a member of another group, consider using a different PSP group that is not currently associated with any other group.
  
  
  
  Modify PSP Group Structure:
  
  If you need to change the structure of your PSP groups, you may need to remove the PSP group from its current group before adding it to a new one. Ensure that this change aligns with your project management requirements.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation or help files related to PSP groups and project structures to understand the rules and limitations regarding group memberships.
