You use bank account posting groups to create linkages between your bank accounts and the central financial statements in the general ledger.
Open the Bank Account Posting Groups window.
In the Code field, enter the code for the group you want to set up. The code should be descriptive; you can use both numbers and letters.
In the G/L Bank Account No. field, click the AssistButton to see the chart of accounts. Select the desired account, and then click OK to copy it to the field.
