Purchase Order Back Orders

Calculates outstanding products in each purchase order marked In Process. Only purchase orders with at least one partially received line item and remaining outstanding quantity are displayed, grouped by supplier with subtotal and final total rows.

• Outstanding qty = ordered qty minus received qty minus canceled qty (per line item).
• A PO appears only when it has outstanding units and at least one line with received qty > 0.
• Supplier — vendor name from pd_purchase_order_supplier (shown once per supplier group).
• PO — purchase order identifier.
• Date Ordered — PO header date.
• Product Qty — sum of remaining units across all line items on the PO.
• Amount — extended cost (outstanding qty × line cost) for the PO.
