Update Purchase Order Costs

Interactive financial admin screen for reconciling inbound purchase order line costs. Select an unbalanced PO from the dropdown to load its product lines, edit individual cost values inline, and push finalized costs into OpenCart product records when ready.

• Select PO — choose an existing unbalanced purchase order from the dropdown; the page reloads with all line items.
• Edit cost — change a line's cost field; the value saves automatically on change and recalculates the line total using received quantity.
• Quantity mismatch — PO quantity and received quantity display in red when they differ.
• Mark balanced — click Mark P/O Balanced and Update Product Costs to write each line cost into oc_product.custom_field key 3.
