# Order Validation & Salesforce Field Mapping Audit Report

## 🔍 **Audit Summary**

### ✅ **What's Working Correctly:**

1. **Core Order Fields** - All documented fields are properly mapped:
   - `AccountId`, `EffectiveDate`, `Status`, `Pricebook2Id`, `Order_Type__c` ✅

2. **Activation Fields** - Correctly implemented:
   - `Activation_Type__c`, `Activation_Scheduled_At__c`, `Activation_Status__c` ✅

3. **Internet Fields** - All documented fields mapped:
   - `Internet_Plan_Tier__c`, `Installation_Type__c`, `Weekend_Install__c`, `Access_Mode__c`, `Hikari_Denwa__c` ✅

4. **SIM Fields** - All documented fields mapped:
   - `SIM_Type__c`, `EID__c`, `SIM_Voice_Mail__c`, `SIM_Call_Waiting__c` + MNP fields ✅

5. **VPN Fields** - Correctly implemented:
   - `VPN_Region__c` ✅

### ⚠️ **Issues Found:**

## **Issue 1: Field Mapping Not Used in Order Builder**

**Problem**: Our `order-builder.service.ts` is hardcoding field names instead of using the field mapping configuration.

**Current Implementation:**
```typescript
// Hardcoded field names
orderFields.Internet_Plan_Tier__c = serviceProduct.internetPlanTier;
orderFields.Access_Mode__c = config.accessMode;
orderFields.Installation_Type__c = installType;
```

**Should Be:**
```typescript
// Using field mapping
const fields = getSalesforceFieldMap();
orderFields[fields.order.internetPlanTier] = serviceProduct.internetPlanTier;
orderFields[fields.order.accessMode] = config.accessMode;
orderFields[fields.order.installationType] = installType;
```

## **Issue 2: Missing Documentation Alignment**

**Problem**: Documentation shows different API structure than implementation.

**Documentation Says:**
```json
{
  "items": [
    { "productId": "...", "billingCycle": "...", "configOptions": {...} }
  ],
  "promoCode": "...",
  "notes": "..."
}
```

**Current Implementation:**
```json
{
  "orderType": "Internet",
  "skus": ["INTERNET-SILVER-HOME-1G", "..."],
  "configurations": { "accessMode": "PPPoE" }
}
```

## **Issue 3: Validation Logic vs Documentation**

**Problem**: Our validation doesn't match documented requirements exactly.

**Documentation Requirements:**
- "Server-side checks: require WHMCS mapping; require `hasPaymentMethod=true`"
- "Create Salesforce Order (Pending Review)"

**Current Implementation:** ✅ Correctly implemented

## **Issue 4: Missing Order Status Progression**

**Documentation Shows:**
- Initial Status: "Pending Review"
- After Approval: "Provisioned" 
- Error States: "Failed"

**Current Implementation:** ✅ Sets "Pending Review" correctly

## **Issue 5: MNP Field Mapping Inconsistency**

**Problem**: Some MNP fields use different patterns.

**Field Map Shows:**
```typescript
mnp: {
  application: "MNP_Application__c",
  reservationNumber: "MNP_Reservation_Number__c",
  // ...
}
```

**Order Builder Uses:**
```typescript
orderFields.MNP_Application__c = true; // ✅ Correct
orderFields.MNP_Reservation_Number__c = config.mnpNumber; // ✅ Correct
```

## **Recommendations:**

### 1. **Fix Field Mapping Usage** (High Priority)
Update `order-builder.service.ts` to use the field mapping configuration instead of hardcoded field names.

### 2. **API Structure Alignment** (Medium Priority)  
Decide whether to:
- Update documentation to match current SKU-based implementation
- OR update implementation to match item-based documentation

### 3. **Add Field Validation** (Medium Priority)
Add validation to ensure all required Salesforce fields are present before order creation.

### 4. **Environment Configuration** (Low Priority)
Ensure all field mappings can be overridden via environment variables for different Salesforce orgs.

## **Overall Assessment: 🟡 MOSTLY CORRECT**

The core functionality is working correctly, but we need to fix the field mapping usage for better maintainability and environment flexibility.
