When an unplanned depreciation is posted to an asset in SAP S/4HANA, the system immediately updates both the Asset Accounting (FI-AA) and the General Ledger (FI-GL) in real time. This ensures that the financial statements reflect the most accurate and up-to-date information without waiting for any periodic posting programs.

FI-AA Posting:

The unplanned depreciation is recorded in the asset sub-ledger, reducing the asset’s book value. The asset master data is updated with the new depreciation values.

Transaction Code: ABAA for unplanned depreciation.

FI-GL Posting:

The corresponding FI-GL accounts are also updated immediately. This includes posting the depreciation expense and adjusting the accumulated depreciation account.

Real-time integration between FI-AA and FI-GL ensures that both ledgers are synchronized, providing a consistent view of the financial data.
