23 Jul 2014 4:20 PM This is an error message that presents itself in a variety of formats...typically when you are first configuring AX, but it can pop up later depending on how you have AX configured. The actual message is: "Account number for transaction type Vendor (or customer, bank, etc.) balance does not exist." I have found that the error is often the "Account Structure". As an example, If you have defined one account structure for your company where you had applied a filter for "Main accounts" and the filter only covered P&L accounts, but all the sub-ledger accounts are of type "Balance"...then you will get this message when you attempt to use the account. The system will not able to find any account structure for balance sheet account, hence it will throw this error. To fix this, all you have to do is to define an account structure for all the accounts.
