• What is the cause and solution for SAP error message AA591 - Depreciation key has more depreciation types than previous deprec. key ?

  The SAP error message AA591 indicates that there is a mismatch in the depreciation keys used for an asset during its lifecycle. Specifically, it means that the new depreciation key assigned to the asset has more depreciation types than the previous depreciation key. This situation typically arises when you are trying to change the depreciation key of an asset that has already been depreciated.
  Cause:
  
  Change in Depreciation Key: The asset was assigned a new depreciation key that has more depreciation types than the previous one. This can happen if the new key includes additional methods of depreciation that were not present in the old key.
  Configuration Issues: The depreciation keys may not be configured correctly in the system, leading to inconsistencies.
  Asset Lifecycle Changes: If the asset has undergone changes in its lifecycle (e.g., transfer, revaluation), and the new depreciation key is not compatible with the previous key.
  
  Solution:
  
  Review Depreciation Keys: Check the configuration of both the old and new depreciation keys in the Asset Accounting (FI-AA) module. Ensure that the new key is appropriate for the asset and that it aligns with the asset's lifecycle.
  Use Compatible Depreciation Key: If the new depreciation key is not necessary, consider reverting to the previous key or selecting a different key that has a compatible number of depreciation types.
  Adjust Asset Master Data: If the asset has been incorrectly assigned a new depreciation key, you may need to adjust the asset master data to ensure that the depreciation key is appropriate for the asset's current status.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team to understand the implications of changing depreciation keys and to ensure compliance with accounting standards.
  Transaction Codes: Use transaction codes like AS02 (Change Asset) to modify the asset master data and ensure that the depreciation key is set correctly.
  
  Related Information:
  
  Depreciation Types: Understand the different types of depreciation (e.g., straight-line, declining balance) and how they are configured in SAP.
  Asset Accounting Configuration: Familiarize yourself with the configuration settings in the Asset Accounting module, particularly regarding depreciation keys and their settings.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling depreciation keys.
  
  If the issue persists after following these steps, it may be beneficial to engage with your SAP support team or a consultant who specializes in Asset Accounting for further assistance.
