• What is the cause and solution for SAP error message WR120 - Partial sales price revaluation not allowed on account of negative stocks ?

  Certainly! Here's a detailed explanation for the SAP error message WR120 - Partial sales price revaluation not allowed on account of negative stocks:
  
  Error Message
  WR120: Partial sales price revaluation not allowed on account of negative stocks
  
  Cause
  This error occurs during a sales price revaluation process (usually in SD or MM-IM integration scenarios) when the system attempts to perform a partial revaluation of sales prices, but there are negative stock quantities for the material in the relevant plant or storage location.
  
  Negative stock means that the system shows that more stock has been issued than received, resulting in a stock quantity below zero.
  SAP does not allow partial sales price revaluation if negative stocks exist because the valuation logic depends on having a positive stock base to correctly calculate the price adjustments.
  Negative stocks can arise due to timing differences in goods receipts and issues, incorrect postings, or inventory inconsistencies.
  
  
  Explanation
  
  Sales price revaluation is typically done to adjust the sales price of a material based on changes in the cost or valuation.
  When the system tries to revalue only a part of the stock (partial revaluation), it needs to know the exact stock quantity and value.
  Negative stock situations make it impossible for the system to correctly calculate the revaluation because the stock quantity is invalid or inconsistent.
  Therefore, SAP blocks the partial revaluation to prevent incorrect pricing or valuation postings.
  
  
  Solution / How to Resolve
  
  
  Check and Correct Negative Stocks:
  
  Use transaction MB52 or MMBE to check stock levels for the material in the plant/storage location.
  Identify where negative stocks exist.
  Investigate the cause of negative stocks (e.g., missing goods receipts, incorrect postings, timing issues).
  Correct the negative stock by:
  
  Posting missing goods receipts (MIGO).
  Adjusting inventory via physical inventory (MI01/MI04/MI07).
  Reversing incorrect goods movements.
  Coordinating with warehouse and inventory management teams.
  
  
  
  
  
  Perform Full Revaluation Instead of Partial:
  
  If partial revaluation is not possible due to negative stocks, consider performing a full sales price revaluation.
  Full revaluation recalculates the price for the entire stock, which may bypass the issue of partial stock inconsistencies.
  
  
  
  Avoid Negative Stocks:
  
  Implement process controls to avoid negative stocks in the future.
  Use availability checks and stock management settings to prevent issuing stock that is not available.
  
  
  
  Check Customizing Settings:
  
  Review the settings in Sales and Distribution (SD) and Inventory Management (IM) related to price revaluation.
  Ensure that the system is configured to handle revaluation correctly.
