Resolve with Vendor Credit

POST 
/api/purchase-invoices/:purchaseInvoice/resolve-with-credit

Resolve an over-billed purchase invoice by issuing a vendor credit for the over-billed quantities and auto-allocating it against the bill.

Authentication: Requires Bearer token.

The credit is created in open status with restock_inventory=false (it's a billing correction, not a physical return). After the credit is allocated, the invoice's approval status is re-evaluated so the variance flag clears automatically when the credit fully offsets the over-bill.

Request body fields:

  • lines (required, min 1): array of { purchase_order_line_id, quantity }. Each quantity must be > 0 and ≤ the over-billed quantity for that PO line.
  • credit_date (optional, nullable, date): defaults to today.
  • supplier_reference (optional, nullable, max 255): defaults to the invoice's supplier_invoice_number.
  • reason (optional, nullable, max 2000): copied into the vendor credit's note.

Validation errors return 422 with a message for: invoice not linked to a PO, PO line not on this invoice, PO line not on this invoice's PO, requested quantity exceeds over-billed delta, or no over-billed quantities provided.

Returns the newly created VendorCredit (eager-loaded with supplier, currency, lines, and allocations).
