• What is the cause and solution for SAP error message WRF_APC096 - Hierarchy node &1 of hierarchy &2 is not an end node ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_APC096: Hierarchy node &1 of hierarchy &2 is not an end node
  
  Meaning / Cause:
  This error occurs in SAP when a hierarchy node that is expected to be an end node (leaf node) in a hierarchy structure is actually not an end node. In other words, the system expects the node to have no child nodes (i.e., it should be a terminal node in the hierarchy), but the node you are trying to use or reference has one or more child nodes.
  This situation typically arises in the context of APC (Activity Price Calculation) or costing hierarchies, where certain operations or calculations require the selection of leaf nodes only.
  
  When does it occur?
  
  When you try to assign or use a hierarchy node in costing or activity price calculation that must be a leaf node but is not.
  When defining or processing hierarchies in SAP Controlling (CO) or Product Costing (CO-PC).
  During the execution of costing runs, activity price calculations, or when working with cost component splits or cost center hierarchies.
  
  
  Explanation:
  
  Hierarchy &2: This is the name or ID of the hierarchy.
  Hierarchy node &1: This is the node within the hierarchy that is being referenced.
  The system expects node &1 to be an end node (leaf node) but it has child nodes, so it cannot be used in the current context.
  
  
  Solution / How to fix:
  
  
  Check the hierarchy structure:
  
  Go to the hierarchy &2 in the relevant SAP transaction (e.g., transaction KCH1 for cost center hierarchies or the relevant APC hierarchy maintenance transaction).
  Verify the node &1 and check if it has child nodes.
  
  
  
  Use a leaf node:
  
  Instead of using node &1, select a node that is an end node (a node without any children).
  If you need to use node &1, ensure that it is converted into a leaf node by removing or reassigning its child nodes.
  
  
  
  Adjust the hierarchy if necessary:
  
  If the business process requires node &1 to be used as an end node, restructure the hierarchy so that node &1 has no children.
  This might involve moving child nodes to other parts of the hierarchy or deleting unnecessary nodes.
  
  
  
  Check configuration and master data:
  
  Ensure that the hierarchy is correctly maintained and consistent.
  Validate that the hierarchy nodes are correctly assigned in master data and costing runs.
  
  
  
  Consult documentation or SAP notes:
  
  Sometimes, specific SAP Notes address issues related to hierarchy handling in APC or costing.
  Search SAP Support Portal for notes related to WRF_APC096 or hierarchy node errors.
  
  
  
  
  Related Information:
  
  Hierarchy nodes in SAP are structured in a tree format, where end nodes (leaf nodes) are nodes without children.
  Many costing and controlling processes require leaf nodes because calculations or assignments are done at the most granular level.
  Transactions to maintain hierarchies include:
  
  KCH1 / KCH2 / KCH3 for cost center hierarchies.
  CKH1 / CKH2 / CKH3 for product cost hierarchies.
  
  
  APC (Activity Price Calculation) uses hierarchies to roll up or distribute costs; incorrect node selection can cause errors.
  Always ensure hierarchy consistency and correctness before running costing or APC processes.
