  Previous Posting: The error arises when there has already been a difference posted for the same inventory item. This means that the system has already recorded a discrepancy between the physical stock and the system stock.
  Source Bin Limitation: The system restricts further adjustments to the source bin where the original difference was identified. This is a safeguard to maintain data integrity and prevent multiple postings for the same discrepancy.
  
  Solution:
  
  Check Previous Postings: Review the inventory postings for the item in question to confirm if a difference has already been posted. You can do this by checking the inventory management documents or the stock overview.
  Adjustments in Source Bin: If you need to make further adjustments, ensure that you are working within the source bin where the original difference was recorded. You may need to perform a stock adjustment or a physical inventory count in that specific bin.
  Use the Correct Transaction: Make sure you are using the appropriate transaction code for posting differences. In EWM, this might involve using the correct inventory adjustment or stock transfer transactions.
  Consult Documentation: Refer to SAP documentation or help resources for specific instructions on handling inventory differences in EWM.
