I have a peculiar prpblem with sales orders. Viewing a list of sales orders in a customer account, some show with a zero balance and some show with a partial balance. Of course, those with a zero balance have been completed in full and closed, having ther cloased tick against each product line. However, those with partial balances yet are also sporting a completed tick make no sense. The entire sales order has been fulfilled yet they show a partial open balance.
Anyone explain what is going on and offer advice on how to correct this please.
