  The SAP error message:
  WRF_APC237: Planning not allowed for hierarchy &1, node &2 (hierarchy level)
  
  
  Cause:
  This error occurs when you attempt to perform planning activities on a hierarchy node or level that is not allowed for planning in the SAP system. Specifically, the planning function is restricted for the particular hierarchy or node you are trying to work with.
  In SAP APO (Advanced Planning and Optimization), certain hierarchy nodes or levels are designated as non-planning nodes. This restriction is often set to prevent planning at summary or aggregated levels where detailed planning data is not maintained or allowed.
  
  Explanation:
  
  Hierarchy &1: The name or ID of the hierarchy.
  Node &2: The specific node within the hierarchy.
  Hierarchy level: The level of the node in the hierarchy.
  
  The system checks the planning authorization or settings for the hierarchy node and blocks planning if it is not permitted.
  
  Common Scenarios:
  
  Trying to plan at a summary node instead of a leaf node.
