# Add Items to Packing Container

## Overview

After creating a Material to be packed and creating a **Packing Container Material**, the user can add new items to the Container.

### Concept

In order to add items to a Packing Container, the user should go to the Resource page and open the **Resource View** and select the option `Add Items`.
Then, a wizard should open with the current material associated with the Container, and in order to add, the user can select Materials manually.

As soon as the MES captures the selected Material it will automatically be added to a temporary list of materials. By clicking in the `Add` option it adds Materials to the Container and generate the Labels for those Materials.

Lastly, the user has the option to `Close the Container` if desired, `Close the Container and TrackOut` that performs the TrackOut after
closing the container and the `Leave` button.

!!! info "Preconditions"
    - The Packing Container Material must have the attribute `IsPackingContainer` set to True
