# Articles & bill of materials

> Link articles to packaging units and track per-article readiness

## Overview

The **Articles** page (sidebar → **Articles**, `/packaging/articles`) shows your products — the same shared article master data the EUDR module uses. It is exactly the same table; in the PPWR context Polygon One merely replaces the EUDR compliance column with the link to packaging units and a readiness indicator.

</Frame>

<Info>
  Articles are **not** created twice. An article visible here is the same record used across all compliance modules.

## Linking articles to packaging units

The link is created on a **packaging unit's detail page** in the **Articles** tab:

<Steps>
  <Step title="Open the packaging unit">
    Open the unit that packages the article and switch to the **Articles** tab.
  </Step>

  <Step title="Select an article">
    Under **Articles**, choose an existing article. Only articles not yet linked to this unit are offered.
  </Step>

  <Step title="Link">
    Click **Link article**. The mapping appears in the list immediately.
  </Step>
</Steps>

</Frame>

To remove a link, use the icon in the row; a confirmation dialog prevents accidental unlinking. The link can be re-established at any time.

<Info>
  There is **no** free-text SKU entry. The article's internal article number **is** the SKU — you only link existing articles.
</Info>

Both directions of the link can also be created via [CSV/Excel import](/en/ppwr/stammdaten/import): the **Article Numbers** column in the units import links an imported unit to existing articles by their internal article numbers.

## What the link is used for

* **Per-article readiness** — an article's readiness is **not** a standalone verdict but the rollup of the obligation statuses of the linked packaging unit(s). The rule: **Action needed** dominates — an article never reads "On track" while a linked unit has an outstanding, in-force obligation. If no unit is linked, a dash is shown.

  | Status            | Meaning                                                 |
  | ----------------- | ------------------------------------------------------- |
  | **Action needed** | At least one linked unit has an outstanding obligation. |
  | **On track**      | Linked units are ready; no outstanding obligation.      |
  | **Upcoming**      | Only obligations that are not yet in force.             |

* **Volumes** — the article ⇄ packaging unit mapping is the basis for attributing packaging volumes to a product (relevant, among other things, for the later volume report).

<Warning>
  Don't confuse the two: the **article link** on this page maps products to packaging units. The **component bill of materials** (which materials a unit contains) is maintained in the **Components (bill of materials)** tab of the packaging unit — see [Packaging units](/en/ppwr/stammdaten/verpackungseinheiten).
