When you perform a physical count and want to adjust the system records to the actual quantities, you need to create an Inventory Count Document to receive the receipts or coupons automatically generated by the System.
If you have not created a "Inventory Count Document", you can correct inventory errors by creating manual vouchers.
If the physical count results in the system are lower than the on-hand quantities, you can create a Stock Issue" for the " Stock Adjustment Voucher to reduce the quantities in the system to match the actual quantities.
