We ask for your understanding that we cannot make a final statement on this, as this may differ from customer to customer.
However, we have compiled the most important points from the HelpDesk entries below to answer this question.
There are two types of BOM in xentral:
-
Bill of material → is stored as a whole set with a number and this is also booked out in shipping.
-
Just-in-time bill of material (set item) → components are put away as individual items and also booked out individually in shipping
A bill of material that is in the warehouse as a finished product with an item number (thus has an inventory). The product, consisting of the individual components of the BOM, is removed from stock as one product during shipping. The components have already been taken from the warehouse during production. Thus, for example, a USB cable in a BOM is part of this BOM and is bound to this BOM from the moment it is placed in stock (it is no longer available as an individual cable for other BOMs).
Parts list that are stored in the warehouse as individual parts, each with its own article number. The parts contained in this BOM type may also be used in other Just-In-Time BOMs. This BOM is removed from stock and scanned as multiple products during shipping. In this way, duplicate storage of different products is avoided.
Thus, for example, a USB cable can be used in many Just-In-Time BOMs without the material in the warehouse being tied to this BOM.
Production items are items that are used in production, i.e. that are to be transferred to the production document when an order is taken forward for production. Products to be produced are always also a "bill of materials". Products that go into the production of another product are only "production items".
The raw materials list is used as extra information for a product. As a rule, for recipes, products etc. Bills of materials are created. Especially if the products are ordered from the bill of materials or the recipe itself or if they are stored and retrieved.
