  • What is the cause and solution for SAP error message WRF_APC045 - Selected node &1 is not an end node ?

    Certainly! Here's a detailed explanation for the SAP error message:


    SAP Error Message:

    WRF_APC045 Selected node &1 is not an end node


    Cause:

    This error occurs in the context of SAP Advanced Planning and Optimization (APO), specifically within the Production Planning and Detailed Scheduling (PP/DS) or Supply Network Planning (SNP) modules when working with the product structure or network.

    • The message indicates that the user has selected a node (e.g., a product, component, or operation) in a product structure or network that is not an end node.
    • An end node is typically a leaf node in the product structure or network, meaning it has no further child nodes or successors.
    • Certain functions or transactions require the selection of an end node because the operation or planning step applies only to the final elements in the structure (e.g., components that are not further broken down).
    • Selecting a node that has child nodes or successors (i.e., an intermediate node) is invalid for the operation being performed.

    When does this happen?

    • When trying to perform planning, simulation, or detailed scheduling activities that require a specific component or operation at the lowest level.
    • When running heuristics, planning runs, or analyzing product structures where only end nodes are valid inputs.
    • During network or BOM (Bill of Materials) processing where the system expects a leaf node.

    Solution:

    1. Select an End Node:

      • Identify the correct end node in the product structure or network.
      • Use transaction or tool to display the product structure and navigate to the leaf nodes.
      • Select a node that has no further child nodes or successors.
    2. Check Product Structure:

      • Use transaction /SAPAPO/SDP94 (Product View) or /SAPAPO/RRP3 (Product Master) to analyze the product structure.
      • Verify the hierarchy and identify the end nodes.
    3. Adjust the Selection Criteria:

      • If the process or function requires an end node, adjust your selection or filter criteria accordingly.
      • Avoid selecting higher-level assemblies or intermediate nodes.
    4. Consult Documentation or SAP Notes:

      • Review SAP documentation related to the specific planning or scheduling function.
      • Check for any SAP Notes that might provide additional guidance or patches if this is a known issue.

    Related Information:

    • Transactions/Tools:

      • /SAPAPO/SDP94 - Product View
      • /SAPAPO/RRP3 - Product Master
      • /SAPAPO/MC90 - Heuristic Planning
      • /SAPAPO/PPDS - Detailed Scheduling
    • SAP Modules:

      • APO PP/DS (Production Planning and Detailed Scheduling)
      • APO SNP (Supply Network Planning)
    • SAP Notes:

      • Search for notes related to WRF_APC045 or product structure node errors in the SAP Support Portal.
    • General Advice:

      • Always ensure that the node selected for planning or scheduling is appropriate for the operation.
      • Understanding the product structure hierarchy is crucial for effective planning in APO.

    If you provide the exact transaction or scenario where this error occurs, I can help with more specific guidance.
