• Supplier truck arrives with goods
• Driver provides Delivery Order (DO)
• Warehouse receives and inspects goods
• Need to update inventory levels

Database Tables

• tblpreceipttxn - Goods receipt header
• tblpreceiptitem - Line items received
• tblpreceiptmovement - Inventory movement records

  --items '[
    {
      "product_name": "WIRE D1.2-L105.8",

Business Rules

1. Supplier Validation: Must exist in tbl_supplier
2. Product Validation: Must exist in tblproductcode
3. Inventory Update: Automatically updates stock levels
4. PO Linking: Can link to existing PO for tracking
5. No Tax Calculation: GR records quantities only (tax on invoice)

Example Scenarios

Scenario 1: Full Delivery

# All items from PO received
python create-purchase-receipt/main.py \
  --supplier-name "ACTION BOLT" \
  --receipt-date "2025-10-27" \
  --items '[
    {"product_name": "WIRE D1.2", "quantity": 200, "unit_price": 8.50}
  ]' \
  --po-reference "PO25100055" \
  --json

Scenario 2: Partial Delivery

# Only 150 out of 200 units received
python create-purchase-receipt/main.py \
  --supplier-name "ACTION BOLT" \
  --receipt-date "2025-10-27" \
  --items '[
    {"product_name": "WIRE D1.2", "quantity": 150, "unit_price": 8.50}
  ]' \
  --po-reference "PO25100055" \
  --remark "Partial delivery - 50 units backordered" \
  --json

Scenario 3: Multi-Item Delivery

python create-purchase-receipt/main.py \
  --supplier-name "NINGBO" \
  --receipt-date "2025-10-27" \
  --delivery-order "DO-2024000" \
  --items '[
    {"product_name": "WIRE D1.2-L105.8", "quantity": 100, "unit_price": 8.50},
    {"product_name": "WIRE D0.8-L133.5", "quantity": 200, "unit_price": 7.30}
  ]' \
  --json

Integration with Database Agent

# After Document Agent extracts Delivery Order
extracted_data = {
    "document_type": "delivery_order",
    "issuer": "NINGBO METALWIRE PRODUCTS CO.,LTD",
    "do_number": "DO-2024000",
    "po_reference": "PO25100054",
    "delivery_date": "2025-10-27",
    "line_items": [
        {"description": "WIRE D1.2-L105.8", "qty_delivered": 100, "unit_price": 8.50}
    ]
}

# Call skill via Bash
result = bash_tool.execute(
    f"python skills/purchasing/create-purchase-receipt/main.py "
    f"--supplier-name '{extracted_data['issuer']}' "
    f"--receipt-date '{extracted_data['delivery_date']}' "
    f"--delivery-order '{extracted_data['do_number']}' "
    f"--items '{json.dumps(items)}' "
    "--json"
)

Error Handling

Testing

# Test with sample delivery order
python create-purchase-receipt/main.py \
  --supplier-name "NINGBO" \
  --receipt-date "2025-10-27" \
  --items '[{"product_name": "WIRE D1.2", "quantity": 50, "unit_price": 8.50}]' \
  --verbose --json

Notes

• GR updates inventory immediately
• Can create GR without PO (direct receipt)
• Multiple GRs can reference same PO (partial deliveries)
• GR is the SOURCE for Purchase Return (if defects found)
