Balance-Dependent Account Display 

Use

When specifying the accounts to be displayed in a balance sheet item, you can choose whether the account display is balance-dependent or not.

You would use this technique for the fixed asset accounts, which are always displayed under the same item in the balance sheet, irrespective of the balance on the account.

If your bank accounts show a debit balance (that is, you have money at the bank), they are to be displayed as assets under the item "Cash at Bank". However, if the accounts show a credit balance (you are overdrawn at the bank), you want them displayed as liabilities under the item "Payables to bank".
