Default Assignment Rules Tab when creating a course

Content

Hi all,

we have a question regarding the tab "Default Assignment Rules" when creating a new course.
For "Initial Assignment Status" you can select "Request Approved" or "Active".

We would like to know, what is the impact of choosing one respectively the other. So in which case should be selected "Active" and when is choosing "Request approved" more useful?

Are there any documents which provide information about it? So far we have not found anything.

Thanks in advance and best regards
Benedikt
