Accelerating Depreciation so asset becomes fully reserved in under 1 year

 Hello:

We integrated Brazil into our Oracle FA app earlier this year.  Their GAAP books are setup with a Flat depreciation method.  A ledger we are currently integrating uses accelerated depreciation based on if the asset is used in 1, 2, or 3 production shifts, so an asset can actually become fully reserved in under 1 year.  How can we fully reserve an asset in under 1 year, using the Flat depreciation method/rates, when the adjusted rate cannot exceed 100% (based on the message I receive when I try this)?
