Although rare and unlikely, the multiple options feature can change against a contextualised course. The reason would be to ensure that the option for that course remains in line with contextualisation.
You don't need to be on the lookout for this change. We will let you know if the multiple option for a contextualised course ever changes.
When your group has been enrolled in a course that changed from multiple options allowed to a single option allowed, then you will need to update the contextualisation settings for that course. When this occurs, a caption text appears in the Contextualisation tab for those groups that states:
The Course Profile has changed, multiple options are no longer accepted. Please review the settings and click Save to confirm.
All you need to do is choose one option from the sector that best fits the needs of the group and then press the save button at the bottom of the page.
