• What is the cause and solution for SAP error message WRF_APC237 - Planning not allowed for hierarchy &1, node &2 (hierarchy level) ?

  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.
  The hierarchy node is marked as non-planning in the master data or configuration.
  The planning version or planning area settings restrict planning on certain hierarchy levels.
  Authorization or customizing settings prevent planning on that node.
  
  
  Solution:
  
  
  Check Hierarchy Settings:
  
  Go to the hierarchy maintenance transaction (e.g., /SAPAPO/MC90 or relevant transaction).
  Verify if the node &2 in hierarchy &1 is marked as a planning node.
  If it is a summary node, planning might not be allowed. You need to plan at the leaf nodes.
  
  
  
  Adjust Planning Settings:
  
  In the planning area or planning version settings, check if planning is allowed for the hierarchy level.
  Adjust the settings if necessary to enable planning on the required nodes.
  
  
  
  Use Correct Planning Node:
  
  Ensure you are selecting the correct node for planning.
  Typically, planning is done at the lowest level (leaf nodes) of the hierarchy.
  
  
  
  Authorization Check:
  
  Verify if your user has the necessary authorizations to plan on the hierarchy node.
  Check roles and authorizations related to planning.
  
  
  
  Consult Configuration:
  
  Check if any custom logic or user-exits restrict planning on certain nodes.
  Review any BAdIs or enhancements that might block planning.

  Summary:
  The error WRF_APC237 indicates that planning is attempted on a hierarchy node or level where it is not allowed. The solution involves verifying the hierarchy node settings, ensuring planning is done at the correct (usually leaf) node, and adjusting planning area or authorization settings accordingly.
