Final answer:
The SOS owes an item to the unit or individual that requisitioned the item when a due-in detail is established, indicating the management of ordered but not yet received items.
Step-by-step explanation:
When a due-in detail is established after an item has been requisitioned, the Supply Operations Service (SOS) owes the item to the unit or individual that placed the requisition. In a supply chain context, 'due-in detail' refers to the records managed by the SOS indicating items that have been ordered but not yet received. This documentation helps in tracking and inventory management by indicating what items are expected to arrive, thereby enabling better forecast and allocation of resources.
Once established, it becomes the responsibility of the SOS to ensure that the item is delivered to the proper entity as soon as it is received from the supplier. This process is critical in maintaining operational readiness and efficiency within an organization, helping to minimize downtime due to the lack of necessary supplies or equipment.
