This field contains the new inventory value.
If you do not enter a new total value here but have chosen to enter a new unit cost in the Unit Cost (Revalued) field instead, the new total value is calculated by multiplying the value in the Unit Cost (Revalued) field with the number in the Quantity field.
The Inventory Value (Calculated) field holds the current value of the item, and the Amount field shows the difference between the two values. When you post the line, the amount in the Amount field is posted to the Value Entry table in order to create the new inventory value.
