  The SAP error message T1528, which states "Hierarchy tree contains no root nodes; tree will be determined again," typically occurs in the context of hierarchical data structures, such as those used in reporting or master data management. This error indicates that the system is unable to find any root nodes in the hierarchy, which are essential for building the tree structure.
  Causes:
  
  Missing or Incorrect Data: The hierarchy data may be incomplete or incorrectly configured. This could be due to missing entries in the master data or incorrect relationships between nodes.
  Configuration Issues: The hierarchy might not be properly set up in the configuration settings. This could involve missing settings in the relevant customizing transactions.

  Check Master Data: Verify that all necessary master data entries exist and are correctly configured. Ensure that there are valid root nodes defined in the hierarchy.
