Field help (DPRRATG) @ L.V. Expertise X3

The rules for the entry of the depreciation rate are a function of the depreciation method entered:

When one of the following modes are entered, this field cannot be entered, and the rate must be set to 0:
CA (Amortization expense / Gross value), DA (German digressive), DE (Spanish declining), FD (French declining), DX (German mixed declining), DP (Portuguese declining), DV (Portuguese mixed declining), DI (Spanish mixed declining), FM (Shapes and moulds), LG (Line), PR (Progressive), RA (Amortization expense / Net value), RE (Residual), SA (Without depreciation), SY (Softy), UD (Declining balance), UL (Straight line), OU (Operation units)

When the method entered has the value PI (Inflated progressive), AN (Anticipato), OR (Ordinario) or IT (Ordinario/Anticipato), it is mandatory to enter the rate.
When the entered mode is the DB one (Belgian declining), this rate, when entered, must be higher than the linear rate and lower than the double of the straight rate.
