# Increase Maintenance Counters

Reports an explicit batch of maintenance event quantities through the counter service.

![Screenshot of a Business Workflow applying supplied maintenance-counter increment entries.](images/business-workflow-task-increase-maintenance-counters.png)

## Inputs

Set `Increments` in the task details. Use the value editor to select compatible results from earlier tasks.

`Increments` accepts a `System.Collections.ObjectModel.Collection<Cmf.Navigo.BusinessOrchestration.MaintenanceManagement.InputObjects.Helpers.IncreaseMaintenanceCountersObject>`. Enter a C# expression enclosed in `{{ ... }}` directly in this input, or reference an earlier output containing that type.

| Property | Description |
| --- | --- |
| `Entity` | Persisted target entity reference, such as a loaded **Resource** or **Container**. |
| `EventName` | Event name used by the configured maintenance activity. |
| `PrimaryDeltaQuantity` | Optional decimal change in the units of the primary quantity counter. |
| `SecondaryDeltaQuantity` | Optional decimal change in the units of the secondary quantity counter. |

Table 1: Maintenance counter increment properties

## Outputs

Use `Increments`, `Count`, `Message` in subsequent tasks.

??? example "Increment a Resource Runtime Counter"

    This example requires a loaded **Resource** and a maintenance activity configured to count primary quantities in hours for an event named `RuntimeHours`. Replace the event name with the one used by your maintenance configuration.

    1. Use [Load or Refresh Entities](../../core/entities/business-workflow-task-load-entities.md), named `load`, to load the target **Resource**.
    2. Add [Foreach](../../core/logic/business_workflow_task_foreach.md) after `load`. Set **Collection** to `{{$load.Result}}` and **Item Name** to `resource`.
    3. Add **Increase Maintenance Counters** inside the **Handler** branch and name it `increase`.
    4. Enter the following expression in `Increments`:

        ```csharp
        {{new System.Collections.ObjectModel.Collection<Cmf.Navigo.BusinessOrchestration.MaintenanceManagement.InputObjects.Helpers.IncreaseMaintenanceCountersObject> {
            new() {
                Entity = (Cmf.Navigo.BusinessObjects.Abstractions.IResource)$scope.resource,
                EventName = "RuntimeHours",
                PrimaryDeltaQuantity = 0.5m
            }
        }}}
        ```

    5. Use `{{$increase.Count}}` or `{{$increase.Message}}` in a subsequent task inside the same **Handler** branch.

    Each iteration reports a half-hour increment for its **Resource**. The task does not convert units. A `CountOne` counter counts the event instead of using the supplied quantity. `Count` reports the number of submitted entries, rather than the number of counters changed.
