Is your Moving Average Cost (MAC) incorrect? Although there isn't a direct way to change your MAC, the good news is you can influence & 'update' your MAC by creating two Stock Adjustments:
1. The First Stock Adjustment to zero out the stock levels for all items with the incorrect MAC - this will reset the MAC value to Zero.
2. The Second Stock Adjustment to bring the stock levels back up to match what you have On Hand. The Cost Per Item entered here will become the new updated MAC moving forward.
