  Data Entry Errors: Manual entry errors during the posting of transactions can lead to this issue, such as entering a wrong quantity or value.
  
  
  Solution:
  
  
  Check Available Quantities: Verify the current stock levels for the material in question. Use transaction codes like MMBE (Stock Overview) to check the available stock and ensure that the quantity you are trying to reduce is valid.
  
  
  Review Document Flow: Check the document flow related to the material document you are trying to process. Ensure that there are no previous postings that have already reduced the quantity or value you are trying to adjust.
  
  
  Adjust the Reduction Amount: If you find that the amount you are trying to reduce is indeed too high, adjust it to a valid amount that does not exceed the available quantity.
  
  
  Consult with a Colleague or SAP Support: If you are unsure about the quantities or the document flow, consult with a colleague or reach out to SAP support for assistance.
  
  
  Transaction Logs: Review transaction logs or change documents to identify any previous transactions that may have affected the stock levels.
