• What is the cause and solution for SAP error message AC439 - Account should only be able to be posted automatically ?

  The SAP error message AC439 indicates that a specific account is configured to allow only automatic postings. This typically occurs in the context of asset accounting, where certain accounts are set up to handle transactions automatically, such as depreciation or asset acquisition, and not through manual journal entries.
  Cause:
  The error occurs when a user attempts to post a transaction manually to an account that is restricted to automatic postings only.

  Use Automatic Posting:
  
  If the account is correctly configured for automatic postings, ensure that you are using the appropriate transaction codes or processes that trigger automatic postings (e.g., asset acquisition through the appropriate asset transaction).
  
  
  
  Consult with Your SAP Administrator:
  
  If you are unsure about changing the account settings or if the account should remain restricted to automatic postings, consult with your SAP administrator or financial controller. They can provide guidance on whether the account configuration should be modified based on your organization's accounting policies.
