Dear Arcita,
What do you want to do exactly with these purchase orders.
In case you want to re-use them, maintain the purchase order line(s) and reset or set the status code in "Single" maintenance mode. When you re-open one purchase order line the transaction will ask, if the other lines should be re-opened also.
The status is normaly set via the receipt of an order(line). When Cancel BO is yes and the qty receipt is less than the order qty the order(line) will be cancelled (X) or otherwise closed (C).
I hope this could help, otherwise
