What requirement is associated with assembly items that use bins?

The requirement associated with assembly items that use bins is that bins must be designated for any component items. This is because, in the context of inventory management within NetSuite, effective organization and tracking of inventory items is critical. When using bins for assembly items, each component item must have a designated bin to ensure accurate availability and inventory levels are tracked properly. This designation helps streamline the assembly process by facilitating the picking of components from designated storage locations, minimizing confusion and improving operational efficiency.

The other options do not align with the principles of inventory management in NetSuite. For instance, serialized components can still be associated with bins; there’s no restriction against using bins for items that are serialized. Additionally, assemblies can indeed use bins, contrary to the suggestion that they cannot. Furthermore, bin association is not limited to parent items only; it applies across both parent and component items to maintain consistency in inventory tracking.
