I need transaction record details in JSON structure.

Approach:
1. Task: Create transaction record in JSON
2. Complexity: simple - 3-5 fields, minimal nesting
3. Format rules: proper braces/brackets, quoted keys, correct value types
4. Structure: Organize data logically with appropriate nesting
5. Populate fields with realistic example data based on the schema.

Output:
{
  "txn_id": "TXN-60093415",
  "items": [
    {
      "sku": "SKU-40673",
      "qty": 2,
      "price": 118.65
    }
  ],
  "customer_id": "68ad3539-0f4f-4400-8ead-e6ccb788e81a",
  "subtotal": 1240.51,
  "total": 1523.63
}
