Every asset transaction immediately causes a change of the forecasted depreciation. However, it does not immediately cause an update of the depreciation and value adjustment accounts for the balance sheet and profit and loss statements. The planned depreciation is posted to the general ledger when you run the periodic depreciation posting run. This posting run uses a batch input session to post the planned depreciation for each posting level for each individual asset as a lump sum amount. 

The calculation and scheduling of depreciation, interest and revaluation are automatically controlled by keys in the system, or you can control them manually using a special posting transaction. In both cases, planned depreciation from Asset Accounting must be periodically posted to the corresponding asset and expense accounts of the general ledger. You carry out this posting using a batch input session. In addition to the various depreciation types, interest and revaluation, this batch input session also posts the allocation and writing off of special reserves. 

When the system posts depreciation, it creates collective documents. It does not create separate documents for each asset.

Depreciation Posting Run is done via transaction code 'AFAB'.

The program creates batch input sessions for posting depreciation and interest to the G/L accounts in Financial Accounting and/or to Controlling.
