Perhaps, the following might be a solution that can be implemented safely in a production setup:
Objective: To post retirement related depreciation in a single period without smoothing over the remaining periods.
Solution:
- Perform standard depreciation posting run for current period
- Turn Smoothing Indicator Off
- Write Off Asset
- Run Repeat Depreciation Posting Run (select Repeat Posting Run instead of planned and also input the retired asset number)
- Turn Smoothing Indicator back on
This should post the complete depreciation in the current period for the retired asset and smooth out the depreciation for all remaining assets
