There is a standard NetSuite button that can be found on a sales order. It is accessible, if and only if the status of the case is not Pending Approval, Billed, or Closed. Also, once the status of the sales order is set to close, you cannot access the said record any longer because it would be locked by standard NetSuite settings. You are allowed to get the values from the sales order but you will not be able to change any of it. An enhancement is now filed for this case: 216263 SS > Scripts/Workflow do not fire when Sales Orders are closed Since the record is now locked and cannot be accessed, here is an alternate solution for this problem.
