Site has a date module, where customer chooses a delivery date for an order. there are four weeks where customer can choose from. items changes for each week. we show Four weeks. each week has differnt items. Once items in a particular week is sold, we show that week as sold out. But a customer is allowed to order items in the rest of the weeks..
Now the fix needed is: We want to do daily stock maintenence instead of weekly. If a day in a week is sold, it is to be set as sold out, but rest of the days in that week are open. same as in the other three weeks.
