Edit the book settings
Go to Application Management / Cash & Cards / Books and edit the book by clicking on the pencil icon. Under the heading 'Organizational unit', you will see which organizational unit the book is linked to:
You can move the book to another desired organizational unit. Employees linked to the book with a role will be automatically unlinked. When using a Cash & Card function profile, existing roles on the new organizational unit are automatically linked to the book. Of course, it's a good idea to check the role overview after changing the organizational unit.
