• What is the cause and solution for SAP error message AY165 - Deprec. simulation data already exist - copying is not necessary ?

  The SAP error message AY165, which states "Deprec. simulation data already exist - copying is not necessary," typically occurs in the context of asset accounting when you are trying to copy or simulate depreciation data for an asset that already has existing simulation data.
  Cause:
  The error arises because the system detects that there is already simulation data for the asset in question. This means that the depreciation simulation process has already been executed for that asset, and the system does not allow for duplicate entries or overwriting of existing simulation data.
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check Existing Simulation Data: 
  
  Navigate to the asset in question and check if there is already simulation data present. You can do this by using transaction codes like AS03 (Display Asset) or AS02 (Change Asset) to view the asset's details.
  
  
  
  Delete Existing Simulation Data: 
  
  If you determine that the existing simulation data is no longer needed, you can delete it. This can typically be done using transaction code AS11 (Display Depreciation Simulation) or AS12 (Delete Depreciation Simulation). Ensure that you have the necessary authorizations to perform this action.
  
  
  
  Re-run the Simulation: 
  
  After deleting the existing simulation data, you can re-run the depreciation simulation for the asset. Use the appropriate transaction code (e.g., AFAB for running depreciation) to perform the simulation again.
  
  
  
  Review Configuration: 
  
  If this issue occurs frequently, review the configuration settings for asset accounting to ensure that the processes are set up correctly and that there are no conflicts in the simulation and depreciation processes.
  
  
  
  Consult Documentation: 
  
  Refer to SAP documentation or help resources for more detailed guidance on handling depreciation simulations and related error messages.
  
  
  
  Contact SAP Support: 
  
  If the issue persists or if you are unsure about the steps to take, consider reaching out to SAP support for assistance. They can provide more specific guidance based on your system configuration and version.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as AS01 (Create Asset), AS02 (Change Asset), AS03 (Display Asset), AFAB (Run Depreciation), and AS11/AS12 (Depreciation Simulation).
  Asset Accounting Configuration: Understanding the configuration settings in the Asset Accounting module can help prevent similar issues in the future.
  User Authorizations: Ensure that you have the necessary authorizations to view and modify asset data, as this can impact your ability to resolve the error.
  
  By following these steps, you should be able to address the AY165 error and successfully manage depreciation simulations for your assets in SAP.
