• What is the cause and solution for SAP error message AC318 - The entry for the depreciation key was completely masked ?

  The SAP error message AC318, which states "The entry for the depreciation key was completely masked," typically occurs in the context of asset accounting when there is an issue with the configuration of the depreciation key or the asset master data.
  Cause:
  
  Depreciation Key Configuration: The depreciation key may not be properly configured in the system. This can happen if the key is set up to mask all entries, meaning that it does not allow for any depreciation calculation.
  Asset Master Data: The asset master record may have incorrect or incomplete information, particularly in the fields related to depreciation.
  Depreciation Areas: There may be issues with the configuration of depreciation areas, such as missing settings or incorrect assignment of the depreciation key to the asset.
  Posting Periods: The posting periods may not be open for the asset, preventing any depreciation from being calculated or posted.
  
  Solution:
  
  
  Check Depreciation Key Configuration:
  
  Go to the configuration settings for the depreciation key in the SAP system (Transaction code: OADB).
  Ensure that the depreciation key is set up correctly and that it allows for depreciation calculations.
  
  
  
  Review Asset Master Data:
  
  Use transaction code AS03 to display the asset master record.
  Check the depreciation key and ensure that all required fields are filled out correctly.
  Make sure that the asset is assigned to the correct company code and that all relevant data is complete.
  
  
  
  Verify Depreciation Areas:
  
  Check the configuration of depreciation areas (Transaction code: OAYZ).
  Ensure that the depreciation key is assigned to the correct depreciation area and that the area is configured to allow for depreciation.
  
  
  
  Check Posting Periods:
  
  Ensure that the posting periods for the asset are open. You can check this in the period control settings (Transaction code: OB52).
  If the periods are closed, you may need to open them to allow for depreciation postings.
  
  
  
  Consult Documentation: If the issue persists, refer to SAP documentation or consult with your SAP support team for further assistance.
