Depreciation key calculating unreliably for complex assets

Hi experts,

My client requires a deprecation key that depreciates in a straight line throughout the life of it's assets. The depreciation of assets should be calculated from when it was capitalized. The key should work out the depreciation for future periods for the duration of the life of the asset, comparing it's expected depreciation to what has already been posted, whereby it will do a catch up to account for the difference and then post depreciation as normal.

The key works as expected but for more complex assets, such as revaluations. Here there are some issues including; the key works as expected until the last couple of years of useful life, whereby depreciation jumps to triple the charge. In other scenarios, the depreciation calculates as expected until the last couple of years until which it stops, leaving net book value forever.

Have you any inkling as to why these issues are occurring?

The key is set up in the following way:

Transaction AFAMA:

  • Maximum amount: N/A
  • Cutoff val. Key: N/A
  • No ord. depreciation with special depreciation: N/A

  • Chnge. Method: No automatic changeover
  • Changeover%rate: 0.0
  • Multiple shift: Increase in depreciation and expired useful life

  • 3.Base method: 0007 (Ordinary: percentage from life (after end of life))
  • Type of depreciation: Ord.depreciation

    Dear customer,

    The base value "02 Half of acquisition value" includes the indexed acquisition values (revaluation), but the base value "01 Acquisition value".
    This could be the reason.

    best regards
