• What is the cause and solution for SAP error message WRF_APC106 - Node &1 does not exist ?

  The SAP error message:
  WRF_APC106 Node &1 does not exist
  typically occurs in the context of SAP Advanced Planning and Optimization (APO), specifically within the Demand Planning (DP) or Supply Network Planning (SNP) modules when working with planning books, data views, or during data transfer processes.
  
  Cause
  
  The error indicates that a specified node (location or product node) referenced in the planning book, data view, or during data transfer does not exist in the system.
  This can happen if:
  
  The node ID is incorrect or misspelled.
  The node has been deleted or is inactive.
  The node is not maintained in the master data (e.g., location master, product master).
  There is a mismatch between the planning book/data view and the master data.
  During data transfer (e.g., CIF or DP data transfer), the node referenced in the data does not exist in the target system.
  
  
  
  
  Solution
  
  
  Verify Node Existence:
  
  Check if the node mentioned in the error message actually exists in the system.
  Use transaction /SAPAPO/LOC3 (Location Master) or /SAPAPO/MAT1 (Product Master) to verify the node.
  If the node is a location, ensure it is active and correctly maintained.
  
  
  
  Check Planning Book and Data View:
  
  Review the planning book and data view settings to ensure that the node is included in the selection.
  Adjust the planning book or data view to include only existing nodes.
  
  
  
  Master Data Consistency:
  
  Ensure that master data is consistent and synchronized between SAP ERP and SAP APO.
  Run CIF (Core Interface) to transfer master data again if necessary.
  
  
  
  Data Transfer and Integration:
  
  If the error occurs during data transfer, check the source data for references to non-existent nodes.
  Correct or remove invalid node references in the source system.
  
  
  
  Recreate or Reactivate Node:
  
  If the node was deleted or inactive but still required, recreate or reactivate it.
  
  
  
  Check Authorizations:
  
  Sometimes, the node exists but the user does not have authorization to access it, leading to this error.

  Notes and Documentation:
  
  Check SAP Notes related to WRF_APC106 for any known bugs or patches.
  Review APO master data synchronization guides to avoid master data inconsistencies.
  
  
  
  Common Scenarios:
  
  After system copy or transport, master data might be missing or inconsistent.
  After deletion of locations or products, planning books or data views still reference them.
  During initial setup or configuration of planning books, incorrect node IDs are used.
