How to Run

To explore Place Order:
  1. Open the Sample API project.
  2. Navigate to the REST Lab.
  3. For the endpoint, select Resource and PartnerOrder.
  4. Enter the following request body in the Request Body:
    Request Body
        "is_ready": false,
        "approving_officer": "G PO.1",
        "salesrep_name": "A. Lincoln",
        "customer_name": "Gloria's Garden",
        "LineItems": [
         {   "product_name": "Hammer",
    "quantity_ordered": 1
  5. Click POST.
    The following response is expected:


Next, you define one or more rules that solve the identified behavior, Check Credit. The logic triggered by each LineItems insertion is summarized as follows:

 Object Watches for Reacts by Which chains to
 LineItems.amount inserts, deletes or changes to quantity or partPrice Computes amount Orders.amount_un_paid
 Orders.amount_un_paid attribute amount adjusts amount_un_paid  Customer.balance
 Customer.balance amount_un_paid adjusts balance Validation checkCredit
 Validation checkCredit balance accept or reject transaction
