If you have added Child work orders to a Parent WO via the Children tab - on the Parent WO how do you view the WO Costs of just the Parent Work Order? As I see it the Parent WO includes the costs of the parent and the child work orders.
Since cost rolls up to the Parent Work Order, once you add a child the cost will be combined on the cost summary tab and there isn't a way to see only the parent cost unless you look at how much the child WO cost is and subtract it from the total cost of the parent work order. However, if for some reason you wanted to un-link the parent and child work orders, you could go to the child tab on the parent work order and delete that child work order and the cost summary tab will go back to only showing the parent work order cost.
