Initial Asset Module Set-up

My agency set-up our Assets module prior to my employment. The module was set-up with monthly depreciation but our agency depreciates assets only annually due to state reporting requirements. I am trying to set-up a new Asset Book and I'm running into challenges with aligning a depreciation calendar and a prorate calendar so that I can start migrating assets from our legacy database into our new Asset book. Anyone with any experience on initial book set-up I'd love to chat with, please.

Thank you,

Brad
