• What is the cause and solution for SAP error message LT081 - Negative stock not possible for storage unit management ?

  The SAP error message LT081, which states "Negative stock not possible for storage unit management," typically occurs in the context of Warehouse Management (WM) when dealing with Storage Unit Management (SUM). This error indicates that the system is trying to process a transaction that would result in negative stock levels for a storage unit, which is not allowed in SAP.
  Cause:
  
  Negative Stock Configuration: The system is configured to disallow negative stock levels for storage units. This is a common setting in many organizations to maintain accurate inventory levels.
  Incorrect Stock Movement: The transaction being processed (such as a transfer order, goods issue, or goods receipt) may be attempting to remove more stock from a storage unit than is currently available.
  Stock Deletion or Adjustment: If stock has been deleted or adjusted incorrectly, it may lead to a situation where the system believes there is insufficient stock to fulfill a request.
  Data Inconsistencies: There may be inconsistencies in the stock data, such as incorrect stock levels due to previous transactions not being processed correctly.
  
  Solution:
  
  Check Stock Levels: Verify the current stock levels in the storage unit. Use transaction codes like LX03 (Display Stock Overview) to check the stock status.
  Adjust Transactions: If a transaction is causing the error, review it to ensure that it does not exceed the available stock. Adjust the quantities accordingly.
  Review Configuration: If negative stock is required for specific scenarios, consider reviewing the configuration settings in the Warehouse Management module. However, this should be done with caution, as allowing negative stock can lead to inventory inaccuracies.
  Reprocess Transactions: If there are any pending or erroneous transactions, reprocess them after ensuring that stock levels are correct.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific configurations related to your system.
  
  Related Information:
