Floor Stock is typically an inventory that is consumed in production but is not tracked in the perpetual inventory system. Floor stock is different from non-stock inventory since it does actually have an item no and item master record, but rather than tracking quantities in the inventory system, the materials are typically expensed as they are received. A material item for a job can be identified as floor stock on the Material Details tab.

An item marked as Floor Stock is handled differently by the scheduler than other material items.  If an item is marked as Floor Stock, the scheduler will not delay a job/operation for receipt of the Floor Stock item.  That is, regardless of the status of the Floor Stock's Available, Date Expected and Data Received values, the scheduler will never delay a job or operation for Floor Stock.
