## 3. ERP Integration
### 3.1 Supported ERP Systems
- SAP Business One
- Microsoft Dynamics 365
- Oracle NetSuite
- Odoo
- Custom ERP systems
### 3.2 Integration Patterns
**Pattern 1: API-Based Integration**
```javascript
// Sync harvest data to ERP
async function syncHarvestToERP(harvestData) {
// Get harvest log from WIA-AGRI-027
const harvest = await wiaClient.getHarvestLog(harvestData.harvestId);
// Transform to ERP format
const erpInventoryItem = {
productCode: harvest.cropType,
quantity: harvest.quantity,
unit: harvest.unit,
quality: harvest.quality,
harvestDate: harvest.harvestDate,
batchNumber: harvest.batchNumber,
location: harvest.location,
cost: calculateProductionCost(harvest),
metadata: {
systemId: harvest.systemId,
nutrientFormula: harvest.nutrientHistory.formulaId
}
};
// Create inventory entry in ERP
await erpClient.createInventoryItem(erpInventoryItem);
}
```
**Pattern 2: Webhook-Based Integration**
```javascript
// ERP webhook endpoint
app.post('/webhooks/wia-harvest', async (req, res) => {
const event = req.body;
if (event.event === 'harvest.logged') {
const harvestData = event.data;
// Process harvest data
await processHarvestForERP(harvestData);
// Update production tracking
await updateProductionMetrics(harvestData);
}
res.status(200).json({ received: true });
});
```
### 3.3 Data Mapping
| WIA-AGRI-027 Field | ERP Field | Transformation |
|-------------------|-----------|----------------|
| harvestId | productionOrderId | Direct mapping |
| cropType | productCode | Lookup from master data |
| quantity | inventoryQuantity | Direct mapping |
| weight | netWeight | Direct mapping |
| quality | qualityGrade | Map premiumβA, grade_aβB |
| harvestDate | completionDate | ISO 8601 to ERP date format |
| operator | operator | Direct mapping |
| systemId | workCenter | Lookup from system registry |

## 10. Testing & Validation
### 10.1 Integration Testing
```javascript
const { WIAClient } = require('@wia/agri027-sdk');
const assert = require('assert');
describe('WIA-AGRI-027 Integration Tests', () => {
let client;
before(() => {
client = new WIAClient({ apiKey: process.env.WIA_API_KEY });
});
it('should retrieve system status', async () => {
const status = await client.getSystemStatus('HYDRO-SYS-001');
assert(status.systemId === 'HYDRO-SYS-001');
assert(status.status === 'operational');
});
it('should get current sensor data', async () => {
const sensors = await client.getSensorData('HYDRO-SYS-001');
assert(Array.isArray(sensors));
assert(sensors.length > 0);
});
it('should adjust nutrients', async () => {
const adjustment = await client.adjustNutrients('HYDRO-SYS-001', {
targetPH: 6.0,
targetEC: 2.0
});
assert(adjustment.status === 'initiated');
});
});
```
### 10.2 Load Testing
```javascript
const autocannon = require('autocannon');
autocannon({
url: 'https://api.wia.org/agri027/v1/system/HYDRO-SYS-001/status',
connections: 100,
duration: 60,
headers: {
'Authorization': 'Bearer YOUR_API_KEY'
}
}, (err, result) => {
console.log('Requests/sec:', result.requests.average);
console.log('Latency (ms):', result.latency.mean);
});
```
---
## 11. Best Practices
### 11.1 Error Handling
```javascript
async function robustIntegration() {
try {
const data = await wiaClient.getSensorData('HYDRO-SYS-001');
await processData(data);
} catch (error) {
if (error.code === 'RATE_LIMIT_EXCEEDED') {
// Wait and retry
await sleep(60000);
return robustIntegration();
} else if (error.code === 'NETWORK_ERROR') {
// Log and alert
logger.error('Network error:', error);
await alertOps(error);
} else {
// Unexpected error
throw error;
}
}
}
```
### 11.2 Caching Strategy
```javascript
const NodeCache = require('node-cache');
const cache = new NodeCache({ stdTTL: 300 }); // 5 minutes
async function getCachedSystemStatus(systemId) {
const cacheKey = `system:${systemId}:status`;
let status = cache.get(cacheKey);
if (!status) {
status = await wiaClient.getSystemStatus(systemId);
cache.set(cacheKey, status);
}
return status;
}
```
