Use this tab window to view the CRs (Change Requests) on which the selected CO (Change Order) is based. You can create a CO right clicking and selecting Create CO in either Change Requests or Change Request/General. To create a CO on the basis of several CRs, select several rows in Change Requests, right-click and select Create CO. You are not allowed to add CRs in this window, but you are allowed to change CR Level and CR Type.
