# Shortage forecast: spot double-booked tools in time

The **shortage forecast** tells you in good time when things get tight: a tool is reserved for a day but is still with a colleague – or all units are taken and none is left for an unplanned job.

### Where you see shortages

- **In the booking calendar** (*Tools → Booking calendar*) the **Shortage forecast** section sits above the calendar – from today to the end of the selected period. *Show* displays the affected tools in the calendar.
- **When reserving and when planning a pick list**: if the period clashes with another booking, a note with the tool, the days and who has it appears after saving.
- **As a notification**: once a day Tulz checks today and tomorrow. If there is a conflict, the tool crib and foremen of the site get the notification *Shortage: tool double-booked* – a tap opens the booking calendar at that tool.

### The two kinds

- **Conflict**: more is booked for the day than is available – for example a reservation while the tool is still on loan according to its due date, or two planned pick lists for the same tool. Someone needs to act here.
- **All booked**: for tools with several units, every unit is taken. Not an error, but anyone who needs the tool unexpectedly that day will be out of luck.

### Several units

Tools with the same **OEM number** count as one tool with several units – without an OEM number, those with the same name, manufacturer and model. If you have two identical engine supports, only the third booking on the same day is a conflict. For bulk items the quantity counts. A unit that is defective, incomplete, at the calibration service or under repair does not count as available.

### What to do about a conflict

- Bring the colleague's return forward or *Hand over* the loan.
- Move the reservation or the planned pick list to another day.
- Request a unit from another site or from the workshop network.
- If it keeps happening: *Reports → Bottlenecks* shows where a second unit pays off.

Everyone chooses under *My profile → Notifications* whether the notification arrives via bell, push or not at all ("Shortage").
