Dauer berechnen
Eventuell müssen Sie Benutzern häufig eine Möglichkeit geben, anzugeben, wann eine Aufgabe oder ein Prozess fällig ist. Mit der Skripteinbindung DurationCalculator können Sie das Fälligkeitsdatum entweder anhand einer einfachen Dauer oder anhand der relativen Dauer berechnen.
Normalerweise berechnet das Festlegen eines Fälligkeitsdatums die Arbeitszeit und nicht die Gesamtzeit. Bei der Bestimmung des Fälligkeitsdatums wird nur der Teil des Tages berücksichtigt, an dem Arbeit verrichtet wird. Beispiel: Eine Aufgabe ist in 10 Stunden fällig, ist jedoch auf einen Geschäftstagszeitplan beschränkt. Wenn die Arbeit am Montag um 10:00 Uhr beginnt, ist sie wie unten berechnet am Dienstag um 12:00 Uhr fällig.
10am-5pm on Monday (6 hours) + 8am-12pm on Tuesday (4 hours)Informationen zu Zeitplänen, die Sie als Eingaben für die DurationCalculator-Methoden verwenden können, finden Sie unter Zeitpläne erstellen und verwenden.
Dieses Skript veranschaulicht die Verwendung von DurationCalculator zur Berechnung eines Fälligkeitsdatums.
