This field contains the IAS/IFRS amount of the invoiced VAT related to the update amount of the ex-tax receipt value. This amount, which can be forced, must necessarily have the same sign as the update amount. When this amount is negative, it cannot exceed, in absolute value, the current IAS/IFRS VAT amount of the asset. When this amount is forced by the user, the right-click option Recalculation by the software becomes available. Activating it cancels the entry and automatically recalculates the amount using the update amount of the ex-tax receipt value and the invoiced VAT rate.
