• What is the cause and solution for SAP error message M8345 - Price change not allowed, due to negative stock ?

  The SAP error message M8345 ("Price change not allowed, due to negative stock") typically occurs in the context of inventory management and material valuation. This error indicates that a price change for a material cannot be processed because the material has negative stock levels. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Negative Stock: The primary reason for this error is that the material in question has a negative stock balance. This can happen due to various reasons, such as:
  
  Incorrect inventory postings.
  Goods issues that were posted without corresponding goods receipts.
  Errors in stock transfers or adjustments.
  
  
  
  Price Change Restrictions: SAP has built-in controls to prevent price changes when there are inconsistencies in stock levels, as this could lead to inaccurate financial reporting and inventory valuation.
  
  
  Solutions:
  
  
  Check Stock Levels:
  
  Use transaction codes like MMBE (Stock Overview) or MB52 (List of Warehouse Stocks on Hand) to check the stock levels of the material.
  Identify the reason for the negative stock. Look for any recent transactions that may have caused this issue.
  
  
  
  Correct Negative Stock:
  
  If you find that there are incorrect postings, you may need to reverse or adjust those transactions. This can be done using:
  
  MB1A for goods issues.
  MB1B for stock transfers.
  MB1C for other stock adjustments.
  
  
  Ensure that all goods receipts are properly posted to balance out any goods issues.
  
  
  
  Re-evaluate Inventory:
  
  If the negative stock is legitimate (e.g., due to a delay in receiving goods), you may need to wait until the stock is corrected before attempting to change the price again.
  
  
  
  Consult with Finance:
  
  If the material is linked to financial implications, consult with your finance team to ensure that any adjustments made do not affect financial reporting.
  
  
  
  Use Transaction Codes:
  
  You can use MB5B to analyze the stock situation over a specific period to understand the movements that led to negative stock.
  
  
  
  Related Information:
  
  Material Master Data: Ensure that the material master data is correctly maintained, including valuation class and price control indicators.
  Inventory Management Settings: Review the settings in inventory management to ensure that they align with your business processes.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or solutions related to this error message.
  User Authorization: Ensure that you have the necessary authorizations to make changes to stock and pricing.
