A batch's release status is decided by whichever lab report points at it, so the batch and the report need to be linked.

  1. The easiest way is when you add the report: pick the "Inventory batch" in the "Link to batch" section before saving.
  2. If a batch has no report yet, its product page shows "Add report" next to it, which takes you to a new certificate already linked to that batch.

A batch without a linked report shows "No report yet" on its product page and stays in quarantine.
