# MrmBacklogProductTypesComponent

**Kind:** Class

**Source:** `Frontend/src/app/components/dashboard/dashboard-libary/widgets/mrm-backlog-product-types/mrm-backlog-product-types.component.ts` (line 45)

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

`MrmBacklogProductTypesComponent` is an Angular dashboard widget for displaying backlog product-type data. It checks feature access, loads and initializes dashboard data, calculates display values, and responds to lifecycle and resize events within the dashboard widget library.

**Extends:** `BaseWidgetComponent`

## Where it refuses work

- `MrmBacklogProductTypesComponent` stops the work with an early return when `this.dashboardLibraryService.checkFeatureSubscription(this.widget.chartEnumId)`.
- `MrmBacklogProductTypesComponent` stops the work with an early return when `month.MonthId == 12`.
- `MrmBacklogProductTypesComponent` stops the work with an early return when `month.TotalValue < this.data[bIndex].MrmBooking[index - 1].TotalValue`.
- `MrmBacklogProductTypesComponent` stops the work with an early return when `month.TotalBookingMonth < this.totalBookingMonths[index - 1].TotalBookingMonth`.
- `MrmBacklogProductTypesComponent` stops the work with an early return when `month.TotalForecastMonth < this.totalBookingMonths[index - 1].TotalForecastMonth`.
- `MrmBacklogProductTypesComponent` stops the work with an early return when `month.MonthId >= new Date().getMonth() + 1`.

function refreshBacklogProductTypes(
  component: MrmBacklogProductTypesComponent,
): void {
  if (!component.checkFeatureSubscription()) {
    return;
  }

  component.getDashboardData();

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

  console.log({
    performancePercentage,
    monthName,
    formattedPrice,
  });
}
```

## AI Coding Instructions

- Call `checkFeatureSubscription()` before requesting or displaying feature-specific dashboard data.
- Keep data loading in `getDashboardData()` and data preparation in `initalizingData()` rather than duplicating initialization logic.
- Preserve the existing method name `initalizingData()` when modifying call sites, including its current spelling.
- Recalculate display-derived values through `calculatePerformancePer()`, `translateMonthName()`, and `getpriceFormatted()` instead of formatting the same values in templates.
- Route resize-related updates through `onResize()` and keep caching behavior within `setChaching()`.
