In the color setup select the date for the “Last Service” under Select attribute. (The field name is optional, but it must be a date field).
When a date field is selected it activates the special functions. Under Value we can now select some operators, while there can be selected an additional field name.
In the example we used the field “Service Interval” – which determines how many days must elapse between each service.
With this interval field, the different operators we achieve the desired effect.
The three operators that can be used are:
before: The date chosen field + interval field to give a date BEFORE today.
equals: The selected date field + interval field to give a date = current date.
After: The chosen date field + interval field to give a date AFTER today’s date.
The three operators require that you select 1 date field and a field service interval.
