Summary

A project admin can re-arrange the columns on a business project board. A business project only has one board within a project but the order of the column can be arranged individually.

Currently, a user with a basic role does not have permission to re-arrange the columns. A user with a trusted role can re-arrange the columns.

Workaround

Via project settings:
Grant the user project admin or member role

OR

Via user management:
Change the role from basic to trusted
