  Review Inventory Valuation Method: If the material is set to use index-based valuation, consider switching to a different valuation method (e.g., moving average or standard price) if LIFO is required for your business processes.
  
  
  Adjust LIFO Settings: If LIFO is necessary, you may need to adjust the settings in the configuration to ensure that it is compatible with the materials being managed in index pools.
