It covers Allow Cost Override on Variation, noting that if enabled, manual edits, bulk imports, or integration price updates can continuously change costs, while disabling it keeps costs driven strictly by PO receipts for audit accuracy. It then reviews costing mode options: last purchase, average, FIFO, and LIFO. The video also explains using an optional lock date to prevent manual edits on layers dated on or before that date, and how material cost defaults control whether receiving PO items to a job use default cost settings or can be overridden by job receipts.
