S3225 - Details

• The SAP error message S3225, "Cannot delete root node," typically occurs when you attempt to delete a root node in a hierarchical structure, such as a tree structure in SAP. This error indicates that the system does not allow the deletion of a root node because it is essential for maintaining the integrity of the hierarchy.
  
  Cause:
  
  Root Node Protection: In many hierarchical data structures, the root node serves as the primary entry point or parent for all other nodes. Deleting it would disrupt the entire structure.
  Data Integrity: The system is designed to prevent actions that could lead to data inconsistency or loss of critical information.
  User Permissions: Sometimes, the user may not have the necessary permissions to perform deletion actions on certain nodes.
  
  
  Solution:
  
  Check Hierarchy Structure: Ensure that you are not trying to delete a root node. If you need to remove a node, make sure it is not the root node.
