# MrmCogsComponent

**Kind:** Class

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

`MrmCogsComponent` is an Angular dashboard widget for loading, initializing, aggregating, and saving cost-of-goods data. It responds to component lifecycle changes, checks feature subscription access, calculates totals by year or month, and formats month and price values for display.

**Extends:** `BaseWidgetComponent`

## Where it refuses work

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

import { ComponentFixture, TestBed } from '@angular/core/testing';
import { MrmCogsComponent } from './mrm-cogs.component';

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

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

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

  it('loads and formats dashboard data', () => {
    component.ngOnInit();

    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

- Call `checkFeatureSubscription()` before requesting or displaying dashboard data that depends on subscription access.
- Keep data loading in `getDashboardData()` and data setup in `initalizingData()` so lifecycle methods remain focused on orchestration.
- Recalculate yearly and monthly sums after dashboard data changes before rendering formatted values.
- Use `translateMonthName()` and `getpriceFormatted()` for display output instead of duplicating formatting logic in templates.
- Preserve the existing lifecycle flow between `ngOnInit()`, `ngOnChanges()`, data initialization, and dashboard persistence.
