**Part of:** [Frontend](subsystem-frontend-src-app)

`MrmProfitLossComponent` is an Angular dashboard widget that prepares and displays profit-and-loss data for the MRM dashboard. It checks feature access, loads or initializes dashboard data, calculates year and month totals, formats prices, and saves dashboard state.

**Extends:** `BaseWidgetComponent`

## Where it refuses work

- `MrmProfitLossComponent` stops the work with an early return when `this.dashboardLibraryService.checkFeatureSubscription(this.widget.chartEnumId)`.
- `MrmProfitLossComponent` stops the work with an early return when `month.MonthId == 12`.
- `MrmProfitLossComponent` stops the work with an early return when `month[propertyName] < this.data[bIndex - 1][propertyName]`.
- `MrmProfitLossComponent` stops the work with an early return when `month[propertyName] < this.totalBookingMonths[index - 1][propertyName]`.
- `MrmProfitLossComponent` stops the work with an early return when `AppSettings.calculateMonthsBeforeToday(month.YearId, month.MonthId -1) == 0 || AppSetting…`.

## Usage

```ts
import { MrmProfitLossComponent } from './mrm-profit-loss.component';

const component = new MrmProfitLossComponent();

// Angular normally calls lifecycle hooks.
component.ngOnInit();
component.ngOnChanges();

if (component.checkFeatureSubscription()) {
  component.getDashboardData();
  component.calculateSumByYear();
  component.calculateSumByMonth();

  const monthName = component.translateMonthName();
  const formattedPrice = component.getpriceFormatted();

  component.saveDashboardData();
}
```

## AI Coding Instructions

- Keep dashboard loading and persistence inside `getDashboardData`, `initalizingData`, and `saveDashboardData` rather than duplicating data setup in lifecycle hooks.
- Check `checkFeatureSubscription()` before requesting or rendering feature-specific profit-and-loss data.
- Recalculate totals through `calculateSumByYear()` and `calculateSumByMonth()` after changing dashboard data.
- Preserve the existing `getpriceFormatted()` method name when calling or updating formatting logic.
- Handle input-driven updates in `ngOnChanges()` and initial setup in `ngOnInit()`.
