  The SAP error message AA648 ("Net book value negative in area & at fiscal year start") typically occurs in the Asset Accounting (FI-AA) module when the system detects that the net book value of an asset is negative at the beginning of a fiscal year. This situation can arise due to various reasons, such as incorrect asset transactions, depreciation settings, or manual adjustments.
  Causes:
  
  Incorrect Asset Transactions: If there are incorrect postings or transactions related to the asset, such as wrong acquisition costs or unrecorded disposals, it can lead to a negative net book value.
  Depreciation Issues: If the depreciation settings are not configured correctly, or if there are errors in the depreciation calculation, it can result in a negative value.

  Run Asset Reports: Use asset reports (e.g., Asset History Sheet) to analyze the asset's history and identify any discrepancies.
  Adjust Values: If necessary, make adjustments to the asset values to correct any negative net book values. This may involve posting additional acquisition costs or correcting depreciation postings.
  Consult with Finance Team: If the issue persists, consult with your finance or accounting team to ensure compliance with accounting standards and practices.
