I am confused by your statement. You said the value for the inventory value shows and the report variable to show this figure is NVL(sum_cost, 0). But the one showing 0 is the qty on hand, so I understood that the qty on hand must use another variable or field and that is what I thought must have a NULL value in. Maybe you can try to explain the problem better, please?
