This guide covers error messages you may see when managing groups. For how groups and group access work, see Groups overview. For making programmes available to groups, see Add a programme to a group.
"Learner groups cannot be moved between hierarchies"
What it means: you tried to move a group to a different root group or hierarchy. Groups can't be moved between hierarchies, even if no learners are in them. This is by design.
What to do: if you need the group in another hierarchy, create a new group with the same name in the right root group. You can then delete the old group if it's no longer needed. See Delete a user group.
"Please specify the employer group"
What it means: you're saving an employer user's profile without an employer group. Employer Groups is a mandatory field, because every employer user must be linked to at least one employer organisation.
What to do: assign the employer user to at least one employer group, then save. See Employer groups.
