Table-Specific Information

Creating Asset Types

An AssetType can be created with one of two methods of computing depreciation. The first is according to a fixed percentage (in this example, 0.15%):

INSERT INTO AssetTypes (
  AssetTypeName,
  FixedAssetAccountId,
  DepreciationExpenseAccountId,
  AccumulatedDepreciationAccountId,
  BookDepreciationSetting_DepreciationMethod,
  BookDepreciationSetting_AveragingMethod,
  BookDepreciationSetting_DepreciationRate
)
VALUES (
  'Vehicles',
  '8e968d1a-5e25-4dad-b6f9-c8f4d72c0cac',
  '20b36596-3d1d-4789-9f08-50c92d19d522',
  '2a9bb066-3398-40e8-a953-caaabed2b7a7',
  'StraightLine',
  'FullMonth',
  0.15
)

Alternatively, you could create an asset type that depreciates according to an effective lifetime:

INSERT INTO AssetTypes (
  AssetTypeName,
  FixedAssetAccountId,
  DepreciationExpenseAccountId,
  AccumulatedDepreciationAccountId,
  BookDepreciationSetting_DepreciationMethod,
  BookDepreciationSetting_AveragingMethod,
  BookDepreciationSetting_EffectiveLifeYears
)
VALUES (
  'Vehicles',
  '8e968d1a-5e25-4dad-b6f9-c8f4d72c0cac',
  '20b36596-3d1d-4789-9f08-50c92d19d522',
  '2a9bb066-3398-40e8-a953-caaabed2b7a7',
  'StraightLine',
  'FullMonth',
  12
)

Updating Asset Types

Since an AssetType must be either using a depreciation rate or an effective lifetime, you must set one field to NULL if you want to change the AssetType to use the other. For example, to change from an effective lifetime to a depreciation rate:

UPDATE AssetTypes
SET BookDepreciationSetting_DepreciationRate = 0.09,
    BookDepreciationSetting_EffectiveLifeYears = null
WHERE AssetTypeId = 'bf28b6ca-3cc6-4591-ac5a-2c1115f04b4b'
