Depending on the specifications in the chart of depreciation and in the asset class, you can manage any number of depreciation areas per asset in the FI-AA component (see Depreciation Areas). Often you are required to post all of these different parallel asset valuations to the general ledger, in order to have these parallel values available at the general ledger level.

You can specify that the posting values from one depreciation area are updated automatically, online to the general ledger accounts (see Features at Chart of Depreciation Level). (Usually you select the book depreciation area as the area for automatic updating to Financial Accounting). You can update other depreciation areas to the general ledger using periodic processing (see Parallel Valuation). Depreciation can only be updated during periodic processing (see Posting Depreciation).
