I'm very new to PDM Admin and am wondering about approvals written to the Drawing/File card. I currently have one workflow for submission and approvals which works fine and auto writes the Approver's Name and date on the card for an first approval release, but when an ECO is approved the first release Approval should not change. Do I need a second workflow just for ECO's and then indicate on a separate Tab the drawing Approval connected to the ECO?
