        {
                foreach (INReplenishmentItem item in Base.Records.Select())
            {
                INReplenishmentItem Rep = PXSelectJoin<INReplenishmentItem, LeftJoin<INItemClass,
                On<INReplenishmentItem.FK.ItemClass>>,
        Where<INReplenishmentItem.siteID, Equal<Required<INReplenishmentItem.siteID>>,
            And2<Where<
                Current<INReplenishmentFilter.itemClassCDWildcard>, IsNull,
                Or<INItemClass.itemClassCD, Like<Current<INReplenishmentFilter.itemClassCDWildcard>>>>,
            And2<Where<
                INReplenishmentItem.launchDate, IsNull,
                        Or<INReplenishmentItem.launchDate,

                        item.QtyPOOrders = Rep.QtyPOOrders;
                        item.QtyPOPrepared = Rep.QtyPOPrepared;
                        Base.Records.Update(item);
                    }   //yield return item;
