# Close Experiment

:lock: Experiment.**Close**

## Overview

This operation is used to close an **Experiment**.

## Setup

No special setup is required other than to meet the preconditions of the transaction.

## Preconditions

* The Experiment exists, is Active and is in the system state Completed.

## Sequence of Steps

### Step 1

1. Select an **Experiment**. To be able to close it, it needs to be active and in state *Completed*.
2. Optionally, edit the Result of the **Experiment** before closing it. You can choose one of the following Experiment Results:
    * Success
    * Failure
    * Inconclusive
3. Add a Conclusion of the **Experiment** (optional).
4. If necessary, enter a comment (optional).
5. Once you have finished editing the **Experiment** results, click on **Close**. The system will confirm that the **Experiment** has been closed successfully.

!!! note
	The **Experiment** closure can also be done automatically if the new **Experiment Definition** has been configured as "Close Experiment Automatically = true". In this case, after all materials/sub-materials have performed all the actions in all the Steps, the Experiment will be closed automatically. However, it can still be edited before being closed by the system.
