• What is the cause and solution for SAP error message APB_FPM_TEST018 - Root level Nodes cannot be moved across trees ?

  The SAP error message APB_FPM_TEST018 indicates that there is an attempt to move a root-level node across different trees in the FPM (Floorplan Manager) application. This error typically arises in scenarios where the structure of the tree nodes is being manipulated, such as in a UI configuration or during runtime operations.
  Cause:
  The root-level nodes in a tree structure are typically the topmost nodes that serve as the starting point for the hierarchy. In SAP FPM, these nodes are not meant to be moved across different trees because they represent distinct hierarchies. Attempting to do so violates the structural integrity of the tree, leading to this error message.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Node Structure: Ensure that you are not trying to move a root node from one tree to another. If you need to reorganize nodes, make sure that you are only moving child nodes within the same tree.
  
  
  Review Configuration: If this error occurs during configuration, review the FPM configuration settings to ensure that the tree structures are correctly defined and that you are not inadvertently trying to manipulate root nodes.
  
  
  Use Correct Methods: If you are using custom code or enhancements, ensure that you are using the appropriate methods for moving nodes. Use methods that are designed to handle child nodes rather than root nodes.
  
  
  Consult Documentation: Refer to the SAP documentation for FPM and tree structures to understand the limitations and proper usage of tree manipulation functions.
  
  
  Debugging: If the issue persists, consider debugging the application to trace where the attempt to move the root node is being initiated. This can help identify the exact point of failure.
  
  
  Related Information:
