Cause

As explained in the long text of the error message:
Inserting object (Cost element group: AA) is not possible. The object contains values/intervals that would lead to overlaps with already existing values/intervals.

It means, if you want to attach lower level cost element group, you need to mak sure there is no duplication assignment of cost elements.

Resolution

To verify the same, you can use the app Display Cost Element Groups.

Menu - Extras - Check and Help Functions - Compare Two Groups
Display matches

There you will find the duplicated cost elements assigned to both groups.
