# Tutorial - Container Update Attributes

## Introduction

In this tutorial, you will update the volume of five 384-well plates using the Container - Update Attributes workflow.

## Prerequisites

              Required permissions and setup

              

**Sample Processing** role is required to access this workflow.

**Required system configuration:**

- Container Usage: `Inventory`

These should exist by default in the Sample application.

### Items

Containers and Locations created from Discngine Sample’s automation will be used:

- 5 plates 384 (150 uL – 10 mM). Layout with columns 1 and 24 as empty.
- “Paris” location.

## Workflow

### Job Creation

[Create a new job](/public/docs/jobs-overview#create-a-job) and select the `Container - Update Attributes` workflow.

### Requesting

- Set Source Type as **Plate**
- Specify Request from **Text**
- Copy/paste the plate barcodes in the text area: **PTEST006:PTEST007:PTEST008:PTEST009:PTEST010**
- Click `Add IDs` to confirm. The plates are listed in the added requests.
- Click `Next`

### Task Requesting

You will change the usage and volume of these containers. Choose the task to apply to the selected plates:

- Set Target Usage to **Sample**.
- Set Target Volume to **100 µl**.

Leave the other attributes blank; their values will remain unchanged in the containers.

### Sourcing

The Sourcing page will confirm that the requested operations are compatible with the source plates (see the `Sourced` column).

- Click `Next`.

### Storing

The [Storing step](/public/docs/jobs-overview#storing) allows you to assign a location to the items involved in the job.

- By default, the system keeps the current plate locations. Click `Next`.

A message box asks if you want to increment the Thawing Cycle of the racks. Click `No` to continue.

### Pipe & Close

The [Pipe & Close step](/public/docs/jobs-overview#pipe-close) provides a summary page where you can review the job and optionally pipe it to another workflow. For this tutorial, click `Close & Quit` to finish the job.
