Hi,
According to me, on AUC Assets no Depreciation should be posted as Depreciation should be only posted yo Assets which are ready for use and AUC assets are in process assets. Once AUC Asset is transferred to Fixed Asset through T-Code AIBU then on such Fixed Asset system should post depreciation. Now in your case if you post Unplanned Depreciation in the month of August then system will calculate the depreciation retrospectively. Now if the last Fiscal year is closed inAsset Accounting and FI then system will recalculate the amount of depreciation from start of fiscal year till August month and post the variation in the September posting else will bifurcate the amount of variation in the remaining useful period of that fiscal year if Smoothing is active. Trasaction type would be 640 and the same will populate automatically in the T-Code ABAA.

Malhar.
