Working time controls which days ION counts as working days when calculating lead times in plans. The value is a standard cron expression. ION reads the day-of-week field (the fifth field) to determine which days count as working days.
For example, * * * * 1-5 means Monday through Friday.
For the full cron specification, see the crontab manpage.
What working time applies to
Working time applies when Autoplan schedules parts your organization makes: parts with a make or dual-source sourcing strategy. When Autoplan counts back from a need date to a start date for a made part, it counts only working days, and the start date always lands on a working day.
Purchased-part lead times always use calendar days. Suppliers quote lead times in calendar time, so a supplier lead time of 35 days means 35 calendar days regardless of the working time setting.
If you record purchased-part lead times in business days, convert them to calendar days when entering them in ION. For a Monday through Friday schedule, multiply by 7/5. For example, 35 business days is about 49 calendar days.
Set working time
- In ION, go to Settings > Supply Chain > Plans.
- In the Working time field, enter a cron expression.
