  • What is the cause and solution for SAP error message WRF_APC115 - Undo not possible; no sales data exists in buffer for material &1 ?

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


    SAP Error Message:

    WRF_APC115 Undo not possible; no sales data exists in buffer for material &1


    Cause:

    This error occurs in the context of Advanced Planning and Optimization (APO), specifically during the Sales and Operations Planning (S&OP) or Demand Planning processes when trying to perform an undo operation on sales data for a particular material.

    • The system tries to undo or reverse a previous sales data entry or planning version.
    • However, it cannot find any sales data in the buffer (the temporary storage area used during planning runs) for the specified material.
    • This usually means that either:
      • No sales data was loaded or planned for the material in the current planning version or buffer.
      • The sales data was already deleted or never existed in the buffer.
      • The planning version or key figure context is incorrect or inconsistent.

    When does it typically occur?

    • During demand planning or S&OP when you try to undo changes or reset sales data for a material.
    • When executing planning functions or macros that involve undoing sales data.
    • When the system expects sales data in the buffer but finds none.

    Solution:

    1. Check if sales data exists for the material:

      • Verify that sales data for the material is actually loaded into the planning version and buffer.
      • Use transaction /SAPAPO/SDP94 or /SAPAPO/SDP7 to check the planning version and key figures.
      • Confirm that the material &1 has sales data in the current planning version.
    2. Reload or re-import sales data:

      • If sales data is missing, reload the sales data from the source system (e.g., ERP system) into APO.
      • Use the CIF (Core Interface) or data transfer processes to ensure sales data is available.
    3. Check planning version and key figure settings:

      • Ensure you are working in the correct planning version.
      • Verify that the key figures related to sales data are correctly defined and active.
    4. Avoid undo operation if no data exists:

      • If no sales data exists, undo operation is not applicable.
      • Skip the undo step or handle the logic in planning macros or functions to check for data existence before undoing.
    5. Check for inconsistencies or buffer issues:

      • Sometimes buffer inconsistencies can cause this error.
      • Try to reset or refresh the planning buffer.
      • Use transaction /SAPAPO/OM17 to manage buffers or restart planning runs.
    6. Consult SAP Notes:

      • Check SAP Notes for any known bugs or patches related to this error message.
      • Example SAP Note: 1234567 (hypothetical) might address buffer or undo issues.

    Related Information:

    • Planning Buffer: Temporary storage used during planning runs to hold data before saving to the database.
    • Sales Data in APO: Typically transferred from ERP systems via CIF interface.
    • Undo Operation: Used to revert changes made during planning runs.
    • Transactions:
      • /SAPAPO/SDP94 - Planning Book for Demand Planning.
      • /SAPAPO/SDP7 - Planning Book for S&OP.
      • /SAPAPO/OM17 - Buffer Management.
    • Key Figures: Metrics used in planning books, e.g., sales quantity, forecast, etc.

    If you provide more context (e.g., transaction, process step), I can help tailor the solution further.
