Fixed Asset Depreciation Not Calculating in Microsoft Dynamics GP

Microsoft Dynamics GPI was on a call with a client the other day looking at a few issues with them in Microsoft Dynamics GP. One of the issues was that they had been setting up the Fixed Asset Management module, but when they ran depreciation, nothing happened.

We did some exploring and the only difference I could find, from who I would have normally configured the module, was that the Fixed Asset Calendar ((Financial » Setup » Fixed Assets » Calendar)) had been configured only for the required years starting in 2020; I usually set it up for a 200 year period.

The first asset being setup was dated in period 12 of 2020 so there is no logical reason why prior years should be needed. However, after we added 2019 into the calendar and re-ran the depreciation, all of the assets depreciated correctly.
