New units can be added in Employees section under "units", either from "create new unit" or first going to "unit list".
In the "unit list" view you can see all existing units. If there are many units, search results can be filtered using the search tool. By ticking "show deleted" also shows deleted units. Click "Add new unit".
The new unit must be given a unique name and code, then press Save. The code maximum length is 50 characters, name maximum is 1000 characters.
If project targeting is in use, a unit can not have same code that's already in use for a project.
The newly created unit is shown in unit list. The unit will automatically be assigned a unique ID. This ID can be used in Units API integrations.
