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.

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:Select an article
Under Articles, choose an existing article. Only articles not yet linked to this unit are offered.

There is no free-text SKU entry. The article’s internal article number is the SKU — you only link existing articles.
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).
