• What is the cause and solution for SAP error message AA258 - Depreciation key & cannot be changed. (& depreciation posted) ?

  The SAP error message AA258 indicates that the depreciation key for an asset cannot be changed because depreciation has already been posted for that asset. This is a common issue in asset accounting when trying to modify the depreciation key after the asset has been in use and depreciation has been calculated.
  
  Cause:
  
  Depreciation Posted: The primary reason for this error is that depreciation has already been posted for the asset in question. Once depreciation is posted, certain attributes of the asset, including the depreciation key, become locked to maintain the integrity of financial data.
  Asset Configuration: The depreciation key is linked to how the asset is depreciated over its useful life. Changing it after posting can lead to inconsistencies in financial reporting.
  
  
  Solution:
  
  Review Depreciation: Check the asset's depreciation history to confirm that depreciation has been posted. You can do this by using transaction codes like AW01N (Asset Explorer) to view the asset's details.
