This error typically arises in the context of SAP's hierarchical data structures, such as when working with ALV (ABAP List Viewer) grids or other tree-like data representations.
  Cause:
  
  Incorrect Data Structure: The data being passed to the function module or subroutine may not be structured correctly, leading to issues when trying to add nodes to the tree.

  Debugging: Use the ABAP debugger to step through the code and identify where the error occurs. Check the values of variables and data structures at runtime.
  Review Code: Look for any programming errors in the function module or subroutine. Ensure that all nodes are being correctly initialized and that there are no null references.
  Configuration Review: If you are using ALV, check the configuration settings for the ALV grid. Ensure that the field catalog and layout are correctly defined.
  Error Handling: Implement error handling in your code to gracefully manage situations where nodes cannot be added.
