# How to manage preventive maintenance events?

- [x] PT

Preventive maintenance event management allows you to recalculate events, adjust dates, and understand the rules that influence how events behave over time.

---

## Reprogram preventive maintenance events

The recalculation of preventive maintenance events is a daily process that recalculates all preventive maintenance events.

This **recalculation** can be done **automatically** or **manually**.

To have the recalculation performed automatically, follow these steps:

1. Access **Settings | Work | Background Services**;
2. Enable the **Enable Event Rescheduling** option.

To recalculate manually, follow these steps:

1. Access **Work | Preventive Maintenance | Preventive Maintenances**;
2. Select the desired **preventive maintenance**;
3. Click on **Operations**, then on **Reschedule Events**.

> [!WARNING]
> If preventive maintenance has already been successfully recalculated on the **same day** (depending on the time zone), **it will not be recalculated again**.

---

## Long-term event planning

Not all events are generated at the time preventive maintenance is approved. They are recalculated over time, according to a set of rules.

**Events based on recurrence**

- **Daily plans**: are scheduled for a maximum of 2 years;
- **Monthly plans with terms up to 24 months**: are scheduled for up to 4 years;
- **Monthly plans with a term longer than 24 months**: can be scheduled for up to 10 years.

**Meter-based events**

The projection depends on the frequency of the events, calculated based on the meter reading average:

- **Up to 7 days**: are scheduled for up to 2 years;
- **From 8 to 365 days**: are scheduled for up to 4 years;
- **From 366 to 730 days**: are scheduled for up to 8 years;
- **More than 730 days**: are scheduled for up to 10 years.

**Events based on recurrence and meter readings**

The projection deadline is defined based on the **recurrence or meter rules**, and the one resulting from the **interval between events** is applied.

> [!WARNING]
> These rules apply to the **approval of preventive maintenance** and to each **recalculation**.

## Change the date of an event

You can change the date of an event on its details page.

To do this, follow these steps:

1. Access **Work | Preventive Maintenance |****Prev. Maint. Events**;
2. Select the **event**;
3. Click **Edit**;
4. On the **Scheduling** tab, change the **Fixed Date** field;
5. Click **Save**.

Any change to an event's date must comply with the following rules:

- The new date cannot be **earlier** than the **previous** event or **later** than the **next** one;
- When preventive maintenance is **rescheduled** (either automatically or manually), events with a **fixed date** retain their **original date**;
- If preventive maintenance **automatically** creates a **work order**, it will be created on the **new event date**;
- If the event already has an associated **work order**, the **date cannot be changed**.

> [!NOTE]
> If you need to **reset** the original date, simply **remove the value from the Fixed Date** field. The next time the system recalculates, the **Expected Date** will be **updated automatically**.

## Calculating events with meters

When preventive maintenance has an **associated meter** and uses scheduling criteria based on the **opening** or **closing** of work orders, the cumulative value of the event is **updated** based on the meter’s **latest reading**.

This occurs when:

- The work order has an **associated preventive maintenance event**;
- The event is the **most recent one** with an associated work order;
- There is a **meter associated** with the preventive maintenance plan;
- The scheduling criterion is **opening** or **closing**.

When the work order is opened or closed, the event value is updated with the current meter reading. In the next recalculation, future events are calculated based on that value.
