Web: Mindestbestand je Lagerort + Einkaufsliste je Ort
- Neuer LocationMinStock-Editor (Zeilen: Lagerort + Menge, separat speichern). - Produktformular: Abschnitt „Mindestbestand je Lagerort" (Menge in Artikel- einheit), zusaetzlich zum Gesamt-Mindestbestand. - Gruppen: je Gruppe ein Editor „Mindestbestand je Lagerort". - Einkaufsliste: Abschnitt „Bedarf: <Lagerort>" mit Produkten und Gruppen, die am Ort unter dem dort hinterlegten Mindestbestand liegen. - API-Methoden set*LocationMinStock und shoppingByLocation.
