# INACBG Modal Implementation Status

## ✅ Completed Features

### 1. Modal UI Component (edit-INACBG.tsx)
- Full responsive modal design
- INACBG code list display with trash icons
- Delete confirmation modal
- Real-time total klaim calculation
- Responsive for all screen sizes (mobile, tablet, desktop)

### 2. Real-Time Calculation Engine
- **Delta-based approach:** Only new codes added/deleted affect calculation
- **Base calculation:** totalKlaim = original total + sum of new codes
- **Deleted codes:** Subtracted from the delta
- **Visual feedback:** Displays total before and after changes

### 3. Delete Functionality
- Click trash icon to confirm delete
- Confirmation modal before deleting
- Automatic recalculation after delete
- Codes removed from display immediately

### 4. API Integration
- Added endpoints: `getTarifBPJSInacbgRI` and `getTarifBPJSInacbgRJ`
- Fetches tarif data for both RI (Rawat Inap) and RJ (Rawat Jalan)
- Full code descriptions displayed for user reference

### 5. Parent Component Integration
- "Edit INACBG" button in INACBG_Admin_Ruangan component
- Replaced old "Edit" button functionality
- Modal opens/closes correctly
- Integration with existing billing data

### 6. Submit to Backend
- Delta payload calculation:
  - New codes added: included in submission
  - Existing codes kept: NOT included (database keeps them)
  - Deleted codes: marked for deletion with delta
- Backend automatically merges changes with existing data

---

## 🔴 Current Issue: Data Display

### Problem
Existing INACBG codes saved in database are NOT appearing in modal when opened.

### Symptoms
- Modal opens correctly
- Total klaim shows correctly (totalKlaimOriginal is loaded)
- INACBG codes list shows: "Belum ada kode INA CBG yang dipilih"
- User cannot see or delete existing codes

### Root Cause
**UNKNOWN** - Debugging in progress. Data flow broken somewhere between:
1. API returns data → 
2. Component loads codes → 
3. Modal receives codes → 
4. UI displays codes

---

## 🔧 Debugging Infrastructure Added

### Console Logging Points

**In Parent Component (INACBG_Admin_Ruangan.tsx):**
```
1. Line 446-449: API response format check
   - Shows kode_inacbg value and type
   
2. Line 463-466: Code loading completion
   - Shows if codes loaded successfully
   - Shows parsed code array
   
3. Line 1534-1539: Button click handler
   - Shows originalInacbgCodes state at click time
   - Shows totalKlaimOriginal value
   
4. Line 388-395: Modal open effect
   - Logs whenever isEditINACBGModalOpen changes
   - Shows all relevant state values
```

**In Modal Component (edit-INACBG.tsx):**
```
1. Line 50-54: State change monitor
   - Logs when selectedInacbgCodes changes
   - Shows current array and length
   
2. Line 130-145: Modal initialization effect
   - Shows currentData received from props
   - Shows type and array detection
   - Shows codes to be set
```

### How Logging Helps
- **Pinpoint exactly where data is lost**
- **Identify data format issues** (string vs array)
- **Verify each step of data flow**
- **Detect state initialization problems**

## 📋 Data Structure

### From API Response
```javascript
{
  kode_inacbg: ["J75", "K45", "L20"],  // Array of code strings
  tipe_inacbg: "RI" | "RJ",
  kelas: "Kelas 1",
  total_klaim: 2776725,
  // ... other fields
}
```

### In Parent Component States
```javascript
originalInacbgCodes: ["J75", "K45", "L20"]  // DB snapshot (never changes)
existingInacbgCodes: ["J75", "K45", "L20"]  // Calculation baseline
selectedInacbgCodes: ["J75", "K45", "L20"]  // Current UI selection
```

### Passed to Modal
```javascript
currentData={{
  kode_inacbg: originalInacbgCodes,         // Should be array
  tipe_inacbg: tipeInacbg,
  kelas: kelas,
  total_klaim: totalKlaimOriginal,
}}
```

### In Modal Component States
```javascript
selectedInacbgCodes: ["J75", "K45", "L20"]  // To display
existingInacbgCodes: ["J75", "K45", "L20"]  // For calculation baseline
```

## 🧪 Testing Checklist

When debugging, verify in order:

- [ ] API returns data with `kode_inacbg` field
- [ ] `kode_inacbg` is an array (not string or object)
- [ ] Array contains code strings ["J75", "K45", etc]
- [ ] `originalInacbgCodes` state updates after API fetch
- [ ] Button click logs show `originalInacbgCodes` with data
- [ ] Modal receives data in `currentData.kode_inacbg`
- [ ] Modal sets `selectedInacbgCodes` from received data
- [ ] UI renders codes list with trash icons
- [ ] Clicking trash button shows confirmation modal
- [ ] Confirming delete removes code from list

## 🎯 Next Action Required

**User must run the application and check browser console (F12) to:**
1. Verify logs appear in expected sequence
2. Identify where data flow breaks
3. Share console output for analysis
4. Based on logs, apply targeted fix

Once console output is reviewed, the specific root cause will be identified and a precise fix applied.
