I am a brand new to NAV and I am trying to set up fixed assets for my company. How do I set up land? The system wants to force me to use a depreciation book even though land is not depreciated. I set up the asset and used the standard depreciation book and straight-line depreciation, but now when I run depreciation I am getting an error because I have not set the useful life for the asset. How do I set up land so it either doesn't require a depreciation book or the system knows to skip that asset when running depreciation?
