Hello, I am using some auto graded assignments from a publishers website that is integrated into my Canvas course. When the assignment is completed the grade is then synced to my Canvas gradebook. Sometimes I need to change the grade sent by the publish. When I do change it, the next day it is overwritten by the publishers sync. Is there a way to lock the grades on an assignment so that it cannot be overwritten by the publishers sync? I know if I set a default grade, that grade will not get overwritten. by the sync.
Have you tried making your update in the publisher's system so that the transferred score is correct?
The publisher systems I've worked with transfer scores on a schedule, and warn that late submissions won't transfer. There might be a setting you could adjust there to avoid daily updates of prior assignments.
If those ideas don't help, all I can suggest is checking do not count towards grades in the canvas assignment settings, and then making another assignment set to "no submission" for you to record the actual grade.
