# Accounts Payable - Events

> **Accounts payable - Events** is the main dashboard where you can analyze the events that occur in the Purchase-to-Pay process from an invoices perspective. Block or change events are recognized as deviations. These are events that you would ideally not want to happen. See the illustration below.

## Introduction

**Accounts payable - Events** is the main dashboard where you can analyze the events that occur in the Purchase-to-Pay process from an invoices perspective. Block or change events are recognized as deviations. These are events that you would ideally not want to happen. See the illustration below.

The information displayed in the dashboard is based on the creation date of the invoices. The **INV creation date** filter in the **Filters** panel enables you to select a period to display the invoices that were created in the selected period.

:::note
Since the process graph displays all invoices which are **created** within the selected period, the graph can also contain changes to these invoices that might be outside the selected period.

### Timestamps

**Throughput time** is the duration between the event end timestamps of two event which follow each other. In this case, waiting time and idle time are also calculated. **Processing time** is the time actually spent on the event. In this case, waiting time and idle time are not taken in to account.

## KPIs

Below is a description of the **KPIs** that are displayed at the top of the **Accounts payable - Events** dashboard.

     KPI  
     Description  
  
 
 
  
     Avg. event throughput time  
     The average event throughput time for invoice events. Note: If you click on the <code>Avg. event throughput time</code> KPI, the <code>Avg. event throughput time</code> metric is selected in the Invoice events dashboard item. 
  
  
     Blocks set  
     The total number of block (set) events on invoices. Note: If you click on the <code>Blocks set</code> KPI, a filter is automatically created and added in the Filters panel. 
  
  
     Changes  
     The total number of change events on invoices. Note: If you click on the <code>Changes</code> KPI, a filter is automatically created and added in the Filters panel. 
  
  
     Main events  
     The total number of main events on invoices. Note: If you click on the <code>Main events</code> KPI, a filter is automatically created and added in the Filters panel. 
  
  
     Total value (invoiced)  
     The total value of the invoices.  
  
  
     Invoices  
     The total number of unique invoices.  
  
 

## Invoice Events

With the **Invoice events** dashboard item you can analyze the Invoices in more detail.

### Metrics

You can create various contexts by selecting different attributes from the drop-down list. The metric selector enables you to select different metrics. Below is a description of the metrics that can be used to analyze the invoices events regarding the selected attribute.

| Metric | Description |
| --- | --- |
| Number of events | The number of unique events, for invoices created within the selected period. |
| Avg. number of events | The average number of events that were performed on invoices that were within the selected period. |
| Percentage of events | The percentage of unique events for invoices created within the selected period, related to the number of invoices. |
| Percentage of invoices | The percentage of invoices per category, compared to unique invoices of all categories, for invoices created within the selected period. |
| Avg. event cost | The average cost of executing events for invoices created within the selected period. |
| Total event cost | The total costs of executing events, for invoices created within the selected period. |
| Avg. event processing time | The average processing time of events for invoices created within the selected period. |
| Total event processing time | The total processing time of event for invoices created within the selected period. |
| Avg. event throughput time | The average throughput time of all events for invoices created within the selected period. |
| Total event throughput time | The total throughput time of all events for invoices created within the selected period. |

## Distribution

The **Distribution** chart enables you to analyze the frequency of events based on the **Event throughput time (end to end). See the illustration below.
