• What is the cause and solution for SAP error message WRF_APC114 - Undo not possible; no purchasing data exists in buffer for material &1 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_APC114 Undo not possible; no purchasing data exists in buffer for material &1
  
  Cause:
  This error occurs in the context of SAP Advanced Planning and Optimization (APO), specifically within the Supply Network Planning (SNP) or Production Planning and Detailed Scheduling (PP/DS) modules when working with the Product Master or Purchasing Data.
  
  The system tries to perform an undo operation on purchasing data for a material.
  However, the buffer (temporary storage area in memory) does not contain any purchasing data for the specified material.
  This usually happens if:
  
  The purchasing data was never loaded into the buffer.
  The buffer was cleared or not updated.
  The undo operation is triggered incorrectly or out of sequence.
  There is a mismatch or inconsistency between the planning data and the buffer content.
  
  
  
  
  Explanation:
  
  In APO, data such as purchasing info records, product master data, and other planning-relevant data are loaded into buffers for performance reasons.
  When changes are made, the system may keep track of previous states to allow undo operations.
  If the system cannot find the original purchasing data in the buffer, it cannot revert the changes, hence the error.
  
  
  Solution:
  
  
  Reload the Purchasing Data into the Buffer:
  
  Use transaction /SAPAPO/MAT1 (Product Master) or relevant transactions to reload the purchasing data for the material.
  Alternatively, run the relevant CIF (Core Interface) integration to ensure the latest purchasing data is transferred from ECC to APO.
  
  
  
  Check Buffer Status:
  
  Verify if the buffer for the material is active and contains the purchasing data.
  You can use transaction /SAPAPO/MAT1 or /SAPAPO/MAT2 to check and maintain product master data.
  
  
  
  Avoid Undo Operation if Not Applicable:
  
  Ensure that the undo operation is only triggered when there is valid data in the buffer.
  Review the process or custom code that triggers the undo to prevent inappropriate calls.
  
  
  
  Clear and Reload Buffers:
  
  Sometimes clearing the buffer and reloading the data can resolve inconsistencies.
  Use report /SAPAPO/OM_REORG or relevant buffer management tools.
  
  
  
  Check CIF Integration:
  
  Ensure that the purchasing data is correctly replicated from ECC to APO.
  Check CIF queues and logs for errors related to the material.
  
  
  
  SAP Notes and Support:
  
  Check SAP Notes for any known bugs or patches related to this error.
  Example SAP Note: 1234567 (hypothetical) — always search SAP ONE Support Launchpad for the latest notes.
  
  
  
  
  Related Information:
  
  
  Transactions:
  
  /SAPAPO/MAT1 - Product Master Maintenance
  /SAPAPO/MAT2 - Product Master Display
  /SAPAPO/OM_REORG - Buffer Reorganization
  CIF Transactions: CFM1, CFM2, CFM3 for integration monitoring
  
  
  
  Concepts:
  
  Buffering in APO: Improves performance by storing master data in memory.
  Undo Operations: Allow reverting changes but require original data in buffer.
  CIF (Core Interface): Integration mechanism between ECC and APO.
  
  
  
  Common Scenarios:
  
  After a product master change in ECC, purchasing data might not be immediately available in APO buffer.
  Undoing changes in APO without proper buffer data leads to this error.
