• What is the cause and solution for SAP error message AC309 - Account &3-&1 not allowed to be defined as reconciliation account ?

  The SAP error message AC309 indicates that the account you are trying to define as a reconciliation account is not allowed to be set up as such. This typically occurs in the context of configuring accounts in the Asset Accounting (FI-AA) module or when dealing with General Ledger accounts.
