Dear All,

I currently have several courses with certificates created for testing purposes, and I want to delete them. However, an error message appears saying, "People already took this quiz. To keep course progression, it should not be deleted."

Could you please advise how I can delete these courses?

Thank you.

Hello Niyas! Thanks for your reply. It is working fine in Odoo 17 and 18. However, in Odoo 15, when I cleared the attendees list and deleted a course, a pop-up error message appeared like 'Validation Error

The operation cannot be completed: another model requires the record being deleted. If possible, archive it instead.

Model: Content Quiz Question (slide.question), Constraint: slide_question_slide_id_fkey'.
