• What is the cause and solution for SAP error message LT221 - Negative stocks not allowed with strategy "R" ?

  The SAP error message LT221, which states "Negative stocks not allowed with strategy 'R'," typically occurs in the context of warehouse management and inventory management when trying to perform a stock transfer or other inventory-related transactions. The error indicates that the system is configured to prevent negative stock levels for the specific storage type or strategy being used.
  Cause:
  
  Stock Strategy Configuration: The storage type is configured with a stock strategy that does not allow negative stock levels. Strategy "R" usually refers to a specific stock management strategy that enforces strict inventory control.
  Stock Levels: The transaction you are attempting to perform would result in a negative stock level, which is not permitted under the current configuration.
  Inventory Management Settings: The settings in the warehouse management or inventory management module may be set to disallow negative stocks for certain types of movements or storage types.
  
  Solution:
  
  Check Stock Levels: Before performing the transaction, verify the current stock levels in the relevant storage type. Ensure that there is enough stock available to complete the transaction without going negative.
  Adjust Inventory: If stock levels are indeed low, consider adjusting the inventory by receiving more stock or correcting any discrepancies in the inventory records.
  Review Storage Type Configuration: If negative stocks are necessary for your business process, you may need to review and potentially change the configuration of the storage type or stock strategy. This can be done in the SAP configuration settings (SPRO) under Warehouse Management settings.
  Consult with SAP Basis or Functional Consultant: If you are unsure about changing configurations or if the issue persists, consult with an SAP Basis or functional consultant who can provide guidance based on your specific system setup and business requirements.
  
  Related Information:
  
  Transaction Codes: You may encounter this error while using transaction codes related to inventory management, such as LT01 (Create Transfer Order), LT10 (Transfer Order Confirmation), or others.
