# ✅ TAT Alerts Display System - Complete Implementation
|
|
|
|
## 🎉 What's Been Implemented
|
|
|
|
Your TAT notification system now **stores every alert** in the database and **displays them in the UI** exactly like your shared screenshot!
|
|
|
|
---
|
|
|
|
## 📊 Complete Flow
|
|
|
|
### 1. When Request is Submitted
|
|
|
|
```typescript
|
|
// First level approver assigned
|
|
Level 1: John (TAT: 24 hours)
|
|
↓
|
|
TAT jobs scheduled for John:
|
|
- 50% alert (12 hours)
|
|
- 75% alert (18 hours)
|
|
- 100% breach (24 hours)
|
|
```
|
|
|
|
### 2. When Notification Fires (e.g., 50%)
|
|
|
|
**Backend (`tatProcessor.ts`):**
|
|
```typescript
|
|
✅ Send notification to John
|
|
✅ Create record in tat_alerts table
|
|
✅ Log activity
|
|
✅ Update approval_levels flags
|
|
```
|
|
|
|
**Database Record Created:**
|
|
```sql
|
|
INSERT INTO tat_alerts (
|
|
request_id, level_id, approver_id,
|
|
alert_type = 'TAT_50',
|
|
threshold_percentage = 50,
|
|
alert_message = '⏳ 50% of TAT elapsed...',
|
|
alert_sent_at = NOW(),
|
|
...
|
|
)
|
|
```
|
|
|
|
### 3. When Displayed in Frontend
|
|
|
|
**API Response** (`workflow.service.ts`):
|
|
```typescript
|
|
{
|
|
workflow: {...},
|
|
approvals: [...],
|
|
tatAlerts: [ // ← NEW!
|
|
{
|
|
alertType: 'TAT_50',
|
|
thresholdPercentage: 50,
|
|
alertSentAt: '2024-10-06T14:30:00Z',
|
|
alertMessage: '⏳ 50% of TAT elapsed...',
|
|
levelId: 'abc-123',
|
|
...
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
**Frontend Display** (`RequestDetail.tsx`):
|
|
```tsx
|
|
<div className="bg-yellow-50 border-yellow-200 p-3 rounded-lg">
|
|
⏳ Reminder 1
|
|
50% of SLA breach reminder have been sent
|
|
Reminder sent by system automatically
|
|
Sent at: Oct 6 at 2:30 PM
|
|
</div>
|
|
```
|
|
|
|

|
|
|
|
## 🎨 UI Display (Matches Your Screenshot)
|
|
|

|
**50% Alert (⏳):**
|
|
- Background: `bg-yellow-50`

|
|
|
|

## 🔄 Complete Data Flow
|
|
|
|
### Backend:
|
|
|
|
1. **TAT Processor** (`tatProcessor.ts`):
|
|
- Sends notification to approver
|
|
- Creates record in `tat_alerts` table
|
|
- Logs activity
|
|
|
|
2. **Workflow Service** (`workflow.service.ts`):
|
|
- Fetches TAT alerts for request
|
|
- Includes in API response
|
|
- Groups by level ID
|
|
|
|
3. **Approval Service** (`approval.service.ts`):
|
|
- Updates alerts when level completed
|
|
- Sets `was_completed_on_time`
|
|
- Sets `completion_time`
|
|
|
|
### Frontend:
|
|
|
|
1. **Request Detail** (`RequestDetail.tsx`):
|
|
- Receives TAT alerts from API
|
|
- Filters alerts by level ID
|
|
- Displays under each approval level
|
|
- Color-codes by threshold
|
|
|

|
|
## 📊 Database Schema
|
|
|
|
### TAT Alerts Table:
|
|
|
|
```sql
|
|
SELECT
|
|
alert_type, -- TAT_50, TAT_75, TAT_100
|
|
threshold_percentage, -- 50, 75, 100
|
|
alert_sent_at, -- When alert was sent
|
|
alert_message, -- Full message text
|
|
level_id, -- Which approval level
|
|
approver_id, -- Who was notified
|
|
was_completed_on_time, -- Completed within TAT?
|
|
completion_time -- When completed
|
|
FROM tat_alerts
|
|
WHERE request_id = 'YOUR_REQUEST_ID'
|
|
ORDER BY alert_sent_at ASC;
|
|
```
|
|
|
|
---
|
|
|
|
## 🧪 Testing the Display
|
|
|
|
### Step 1: Setup Upstash Redis
|
|
|
|
See `START_HERE.md` for quick setup (2 minutes)
|
|
|
|
### Step 2: Enable Test Mode
|
|
|
|
In `.env`:
|
|
```bash
|
|
TAT_TEST_MODE=true
|
|
```
|
|
|
|
### Step 3: Create Test Request
|
|
|
|
- TAT: 6 hours (becomes 6 minutes in test mode)
|
|
- Submit the request
|
|
|
|
### Step 4: Watch Alerts Appear
|
|
|
|
**At 3 minutes (50%):**
|
|
```
|
|
⏳ Reminder 1
|
|
50% of SLA breach reminder have been sent
|
|
Reminder sent by system automatically
|
|
Sent at: [timestamp]
|
|
```
|
|
|
|
**At 4.5 minutes (75%):**
|
|
```
|
|
⚠️ Reminder 2
|
|
75% of SLA breach reminder have been sent
|
|
Reminder sent by system automatically
|
|
Sent at: [timestamp]
|
|
```
|
|
|
|
**At 6 minutes (100%):**
|
|
```
|
|
⏰ Reminder 3
|
|
100% of SLA breach reminder have been sent
|
|
Reminder sent by system automatically
|
|
Sent at: [timestamp]
|
|
```
|
|
|
|
### Step 5: Verify in Database
|
|
|
|
```sql
|
|
SELECT
|
|
threshold_percentage,
|
|
alert_sent_at,
|
|
was_completed_on_time,
|
|
completion_time
|
|
FROM tat_alerts
|
|
WHERE request_id = 'YOUR_REQUEST_ID'
|
|
ORDER BY threshold_percentage;
|
|
```
|
|
|
|

|
|
|
|
## 🎯 Approver-Specific Alerts
|
|
|
|
### Confirmation: Alerts are Approver-Specific
|
|
|
|
✅ **Each level's alerts** are sent to **that level's approver only**
|
|
✅ **Previous approver** does NOT receive alerts for next level
|
|
✅ **Current approver** receives all their level's alerts (50%, 75%, 100%)
|
|
|
|
### Example:
|
|
|
|
```
|
|
Request Flow:
|
|
Level 1: John (TAT: 24h)
|
|
→ Alerts sent to: John
|
|
→ At: 12h, 18h, 24h
|
|
|
|
Level 2: Sarah (TAT: 12h)
|
|
→ Alerts sent to: Sarah (NOT John)
|
|
→ At: 6h, 9h, 12h
|
|
|
|
Level 3: Mike (TAT: 8h)
|
|
→ Alerts sent to: Mike (NOT Sarah, NOT John)
|
|
→ At: 4h, 6h, 8h
|
|
```
|
|
|
|

|
|
|
|
## 📋 KPI Queries
|
|
|
|
### Get All Alerts for a Request:
|
|
|
|
```sql
|
|
SELECT
|
|
al.level_number,
|
|
al.approver_name,
|
|
ta.threshold_percentage,
|
|
ta.alert_sent_at,
|
|
ta.was_completed_on_time
|
|
FROM tat_alerts ta
|
|
JOIN approval_levels al ON ta.level_id = al.level_id
|
|
WHERE ta.request_id = 'REQUEST_ID'
|
|
ORDER BY al.level_number, ta.threshold_percentage;
|
|
```
|
|
|
|
### TAT Compliance by Approver:
|
|
|
|
```sql
|
|
SELECT
|
|
ta.approver_id,
|
|
u.display_name,
|
|
COUNT(*) as total_alerts_received,
|
|
COUNT(CASE WHEN ta.was_completed_on_time = true THEN 1 END) as completed_on_time,
|
|
COUNT(CASE WHEN ta.was_completed_on_time = false THEN 1 END) as completed_late,
|
|
ROUND(
|
|
COUNT(CASE WHEN ta.was_completed_on_time = true THEN 1 END) * 100.0 /
|
|
NULLIF(COUNT(CASE WHEN ta.was_completed_on_time IS NOT NULL THEN 1 END), 0),
|
|
2
|
|
) as compliance_rate
|
|
FROM tat_alerts ta
|
|
JOIN users u ON ta.approver_id = u.user_id
|
|
GROUP BY ta.approver_id, u.display_name;
|
|
```
|
|
|
|
### Alert Effectiveness (Response Time After Alert):
|
|
|
|
```sql
|
|
SELECT
|
|
alert_type,
|
|
AVG(
|
|
EXTRACT(EPOCH FROM (completion_time - alert_sent_at)) / 3600
|
|
) as avg_response_hours_after_alert
|
|
FROM tat_alerts
|
|
WHERE completion_time IS NOT NULL
|
|
GROUP BY alert_type;
|
|
```

## 📊 KPI Reporting Ready
|
|
|
|
### All TAT alerts are now queryable for KPIs:
|
|
|
|
**TAT Compliance Rate:**
|
|
```sql
|
|
SELECT
|
|
COUNT(CASE WHEN was_completed_on_time = true THEN 1 END) * 100.0 /
|
|
NULLIF(COUNT(*), 0) as compliance_rate
|
|
FROM tat_alerts
|
|
WHERE was_completed_on_time IS NOT NULL;
|
|
```
|
|
|
|
**Approver Response Time After Alert:**
|
|
```sql
|
|
SELECT
|
|
approver_id,
|
|
alert_type,
|
|
AVG(
|
|
EXTRACT(EPOCH FROM (completion_time - alert_sent_at)) / 3600
|
|
) as avg_hours_to_respond
|
|
FROM tat_alerts
|
|
WHERE completion_time IS NOT NULL
|
|
GROUP BY approver_id, alert_type;
|
|
```
|
|
|
|
**Breach Analysis:**
|
|
```sql
|
|
SELECT
|
|
DATE(alert_sent_at) as date,
|
|
COUNT(CASE WHEN alert_type = 'TAT_50' THEN 1 END) as alerts_50,
|
|
COUNT(CASE WHEN alert_type = 'TAT_75' THEN 1 END) as alerts_75,
|
|
COUNT(CASE WHEN alert_type = 'TAT_100' THEN 1 END) as breaches
|
|
FROM tat_alerts
|
|
WHERE alert_sent_at >= CURRENT_DATE - INTERVAL '30 days'
|
|
GROUP BY DATE(alert_sent_at)
|
|
ORDER BY date DESC;
|
|
```
|
