  This error usually arises when the system is trying to display or process a tree structure that exceeds the allowed number of regulation nodes. The limitation is often set to ensure performance and manageability of the data structure. The "&1" in the message indicates the maximum number of nodes that can be displayed or processed.
  Solution:
  To resolve this error, you can consider the following approaches:

  Check Configuration Settings: Review the configuration settings related to the regulatory data structures in your SAP system. There may be parameters that define the maximum number of nodes allowed, and these can sometimes be adjusted by a system administrator.
  
  
  Use Alternative Views: If the tree structure is too large, consider using alternative views or reports that can handle larger datasets without hitting the node limit.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on managing tree structures and understanding the limitations in your version of SAP.
  
  
  Contact SAP Support: If the issue persists and you cannot find a suitable solution, consider reaching out to SAP support for assistance. They may provide insights specific to your system configuration or version.
