Purchase order extensions and blanket orders

DXSteel extends the BC Purchase Order with certificate requirements, coverage costs, transport, and processing metadata. Purchase lines carry multiple cost layers via a separate Purchase Line Cost table. Blanket orders support automated cost transfer and conversion to regular orders.

Key header fields

Field	Purpose
Total Amount Coverage	Sum of all order-level coverage costs. Read-only.
Shipment Method Code	Incoterm (FOB, CIF, DDP).
Delivery Time	Estimated arrival.
Transport Route Code	Shipping lane.
Factory	Vendor's producing facility.
Country/Region Production	For Country-of-Origin certificates.
Thickness Norm / Flatness Norm / Surface Norm	Spec requirements for certificates.
Z-Test / Ultrasonic Test / Stamping	Quality test requirements.
Delivery Condition	Special delivery instruction.

Purchase Line Costs — three types

Type	When to use
Charge (Item)	Fixed item-charge increments that raise cost price.
Service (Item)	Service costs (freight, inspection) outside item charge.
Coverage (Item)	Coverage costs with amount/percentage; either order-level or order-line-level.

Blanket-order workflow

Create a Blanket Order with vendor, lines, unit cost.
Add costs via Purch. Line Coverages.
Convert to a regular order with the BC standard action. DXSteel uses CopyPurchPostedCoveragesDMX to copy all coverage costs to the new order.
Receive and invoice on the regular order; the blanket balance decrements.

Best practices

Set unit cost + coverage costs once on a blanket order. Each conversion to a regular order inherits them automatically.

Order-level coverage costs (in Purchase Order Coverages) apply to the whole order; line-level (in Purchase Line Costs) per line. Choose the right layer deliberately.

Cost editing locks for invoices and credit memos. You can only edit costs freely on Open purchase orders.
