In the Fixed Asset module our client wants common depreication rates applied for groups. But in Navision every Asset has to be given the depreciation rate seperately. So I cannot say calculate depreciation for all vehicles where the common rate of depreciation is say 10% Any suggesstions to overcome this Tks

Can you give some more information. What depreciation method are you using? If you are using Straight line and manually specifying the % rate, then all you need is some field on the header to group these together. You could, for example, use the search description.
