Shipment Advice Bill Auto Complete

On a draft vendor bill (in_invoice) or vendor credit note (out_refund), a new "Auto-Complete Shipment" field appears next to the vendor bill reference. You pick a shipment advice that is in state done and has no bill yet; the module then creates the bill lines for you.

• Only incoming shipment advices are accepted, and only those not already linked to a bill.
• If the shipment advice has several suppliers, a warning is shown and nothing is generated.
• If the bill already has a vendor, it must match the shipment's supplier; otherwise the field is ignored. If the bill has no vendor, it is set from the shipment.
• Lines are built from the purchase order lines behind the shipment's done stock moves, using the received quantities, and the vendor, currency, origin and reference are filled in.
• Lines already coming from the same shipment advice are removed before regenerating, so re-selecting does not duplicate them.

On the shipment advice itself you can see the related supplier(s), the linked bill and a read-only "Bill Lines" list. When a bill is created or later modified from a shipment advice, a message is posted in the bill's chatter with a link to the shipment advice. No over-billing check is performed, so the bill must be reviewed manually.
