You can also add a cost unit combination by clicking
next to an existing cost unit combination.
The values of the existing combination will then be prefilled.
1. Click **Add cost unit combination**.
Note: (unspecified) means that no cost unit types underneath will be valid. Let us use the example above with
Departments and Business units, and that you have a 3rd cost unit type called Project.
If you set up the combination R&D - (unspecified), you cannot choose a business unit.
1. Select cost units under each cost unit type.
1. Click **OK**.
## How to assign an approver to a cost unit combination
1. Select the combination.
1. Click **Assign approver.
You can also assign an approver by clicking the person icon next to an existing approver. This will copy that row so you
can easily add an approver with the same role.
1. From the drop-down list, select a [role](../../../../online_help/configuration/roles/).
1. Select an approver.
1. Optional: If you are using branches in Visma.net ERP, you can select a specific branch to assign an approver to.
If you want the approver to receive documents regardless of the branch used in the document, then you can use the "Any" branch.
1. Optional: Select the **Deputy** check box if the approver only receives documents that cannot be approved by the
other approver(s). This function is used to avoid approvers having to approve their own documents.
1. Click **Save**.
