G/L accounts to be used to track AR/AP transactions in G/L are separately recorded for main, second and third chart of accounts. G/L accounts are recorded using the G/L Accounts (Main Chart of Accounts), G/L Accounts (Second Chart of Accounts) and G/L Accounts (Third Chart of Accounts) options located under the Attached Records menu.
The Connection Codes field of the G/L Connection Codes window is used to specify the transactions to which the specified accounts are applied.

Once the transaction is selected, the connection definition is recorded using the "New" option.
