# MrmDepreciationComponent

**Kind:** Class

**Source:** `Frontend/src/app/components/dashboard/dashboard-libary/widgets/mrm-depreciation/mrm-depreciation.component.ts` (line 77)

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

`MrmDepreciationComponent` manages depreciation data for a dashboard widget by initializing, retrieving, saving, and calculating totals by year or month. It also checks feature subscription access and prepares month and price values for display.

**Extends:** `BaseWidgetComponent`

## Where it refuses work

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

## Usage

```ts
import { ComponentFixture, TestBed } from '@angular/core/testing';
import { MrmDepreciationComponent } from './mrm-depreciation.component';

describe('MrmDepreciationComponent', () => {
  let fixture: ComponentFixture<MrmDepreciationComponent>;
  let component: MrmDepreciationComponent;

  beforeEach(() => {
    TestBed.configureTestingModule({
      declarations: [MrmDepreciationComponent],
    });

    fixture = TestBed.createComponent(MrmDepreciationComponent);
    component = fixture.componentInstance;
  });

  it('loads and formats depreciation dashboard data', () => {
    fixture.detectChanges();

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

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

      expect(formattedPrice).toBeDefined();
      expect(monthName).toBeDefined();
    }
  });
});
```

## AI Coding Instructions

- Keep data loading and initialization aligned with `ngOnInit` and `ngOnChanges`.
- Check `checkFeatureSubscription()` before showing or requesting depreciation dashboard data.
- Run `calculateSumByYear()` and `calculateSumByMonth()` only after the required dashboard data is initialized.
- Use `translateMonthName()` and `getpriceFormatted()` for widget display values instead of formatting those values in templates.
- Save changes through `saveDashboardData()` after updating the component’s depreciation state.
