No, Once the learner has completed the course, even if the admin makes changes in the learning item, it has no impact on the transcript. To update the content for a Learner that has previously completed the course, you will need to re-assign the Course with the updated content to the Learner again. This can be done by resetting the completed assignment and either having the user re-complete the Course with the new material or marking them completed again as a Learning Specialist.
To withdraw the user, follow the below steps: As a Learning Specialist, go to My Client Groups -> Learning -> Courses
Search for and select the Course with the updated content.
Go to the Learners tab and search for the user with the old completion.
Select the user in the results and click "Change Status"
Select the option "Undo Complete"
Now the account is in Active status and the Learning Specialist can either use the Bypass and Complete feature to mark the user completed or inform the user that they need to retake the Course with the updated content.
