Field help (DEDVATAMA) 

This field contains the VAT recovery CoA amount related to the update of the receipt value of the asset. This amount is calculated using the CoA amount of the invoiced VAT and the VAT recovery rate. This amount can be forced. It must absolutely have the same sign as the update amount. When the VAT recovery amount is negative, this amount cannot exceed the current VAT recovery amount of the asset, in absolute value. 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 from the CoA amount of the invoiced VAT and the VAT recovery rate.
