Adding an interest dividend to savings account creates a credit and debit, cancelling it out.
I create a sales receipt from a dummy customer called Bank interest. I set the account to a line item also called Bank interest. I then tell it to deposit straight into the savings account. The result is a credit and a debit in the savings account, which cancels each other out. I know you can add bank interest through the reconcile window, but I'm not caught up on reconciling yet. I have old interest amounts I need to enter.
