**Purpose**: Main interface that handles multiple report types based on checkbox selections

**Function Signature**:
```php
// Multiple report types can be selected via checkboxes
$rep1 = $_REQUEST['rep1']; // Sales reports
$rep2 = $_REQUEST['rep2']; // Sales return reports  
$rep3 = $_REQUEST['rep3']; // Combined sales/return reports
$rep4 = $_REQUEST['rep4']; // Purchase reports
$rep5 = $_REQUEST['rep5']; // Purchase return reports
$rep6 = $_REQUEST['rep6']; // Combined purchase/return reports
```

**Process Flow**:
1. Load dropdown data (stores, suppliers, clients)
2. Parse report type selections (rep1-rep6 checkboxes)
3. Route to appropriate report functions based on selections
4. Handle client-specific vs supplier-specific vs general reports
5. Display via appropriate templates

**Report Type Routing**:
```php
if ($clientId > 0) {
    if ($rep1 == '1') showAll(); // Sales reports
    if ($rep2 == '1') returnshowAll(); // Return reports
    if ($rep3 == '1') { showAll(); returnshowAll(); } // Combined
}

if ($supplierId > 0) {
    if ($rep4 == '1') showBuyBill(); // Purchase reports
    if ($rep5 == '1') showBuyReturn(); // Purchase returns
    if ($rep6 == '1') showBuyReturnAndBuy(); // Combined purchase
}
```

## 🧮 Calculation Methods

### Discount Calculation (Fixed vs Percentage)
```php
// Fixed amount discount (type = 1)
if ($sellbilldiscounttype == 1) {
    $totalDiscount = $sellbilldiscount + $detailDiscount;
    $taxValue = $sellbillaftertotalbill - ($sellbilltotalbill - $sellbilldiscount);
}

// Percentage discount (type != 1)
else {
    $discountValue = ($sellbilltotalbill / 100) * $sellbilldiscount;
    $totalDiscount = $discountValue + $detailDiscount;
    $taxValue = $sellbillaftertotalbill - ($sellbilltotalbill - $discountValue);
}
```

### Performance Optimization Techniques
```php
// Batch loading to prevent N+1 queries
$billIDs = array_unique(array_column($sellbillData, 'sellbillid'));
$userDataArr = R::getAll('select userid,employeename from user where userid in(' . implode(',', $userIDs) . ')');

// Array indexing for fast lookups
$userDataArr = customArrayIndexOne($userDataArr, 'userid');

// Join data efficiently
foreach ($sellbillData as &$value) {
    $value['username'] = $userDataArr[$value['userid']]['employeename'];
    $value['clientname'] = $clientDataArr[$value['sellbillclientid']]['clientname'];
}
```

### Serial Number Filtering
```php
if (!empty($proSellTrackingSerial)) {
    // Find bills containing specific product serial
    $detailsData = R::getAll('SELECT distinct sellbillid FROM sellbilldetail where proSellTrackingSerial="' . $proSellTrackingSerial . '"');
    
    // Build IN clause for main query
    $sellbillIds = array_column($detailsData, 'sellbillid');
    $queryStringDetailIds = " and sellbillid in (" . implode(',', $sellbillIds) . ")";
}
```

---

## 🔒 Security & Permissions

### Input Validation
- All `$_REQUEST` parameters filtered through framework
- Date format validation and timezone handling
- Numeric ID validation and type casting
- Serial number format validation
- SQL injection prevention through parameterized queries

### Data Access Control
- Uses standard ERP session authentication
- Respects user permissions from authentication.php
- No additional access restrictions beyond standard login
- Bill condition filtering (conditions = 0 for active bills)

### Query Security
```php
// Safe parameter binding
$queryString .= ' sellbilldate >= "' . $startDate . '" AND sellbilldate <= "' . $endDate . '" AND';

// Condition filtering for data integrity
$queryString .= ' AND sellbill.conditions=0';

// Array indexing prevents injection
$billIDs = array_unique($billIDs);
$queryString .= ' AND sellbillid IN (' . implode(',', $billIDs) . ')';
```

## 📊 Performance Considerations

### Database Optimization Tips
1. **Critical Indexes Required**:
   - `sellbill(sellbillclientid, sellbilldate, conditions, sellbillstoreid)`
   - `sellbilldetail(sellbillid, proSellTrackingSerial)`
   - `sellbillandrutern(sellbillclientid, sellbilldate, conditions)`
   - `returnsellbill(returnsellbillclientid, returnsellbilldate, conditions)`

2. **Query Optimization Techniques**:
   - Batch loading of related data to prevent N+1 queries
   - Array indexing for fast data joins
   - Efficient use of IN clauses for filtering
   - Proper date range filtering with indexes

3. **Memory Management**:
   - Large datasets may require pagination
   - Array indexing reduces memory overhead
   - Object conversion only when necessary
   - Cleanup of temporary variables

### Performance Monitoring
```sql
-- Monitor query performance
EXPLAIN SELECT * FROM sellbill 
WHERE sellbilldate >= '2024-01-01' AND sellbilldate <= '2024-12-31' 
AND conditions = 0 
AND sellbillclientid = 123;

-- Check index usage
SHOW INDEX FROM sellbill;
SHOW INDEX FROM sellbilldetail;
```

---

## 🐛 Common Issues & Troubleshooting

### 1. **Large Dataset Performance**
**Issue**: Reports timeout or run slowly with large date ranges  
**Cause**: Missing indexes or inefficient queries

**Solutions**:
```sql
-- Add required indexes
CREATE INDEX idx_sellbill_date_client ON sellbill(sellbilldate, sellbillclientid, conditions);
CREATE INDEX idx_detail_serial ON sellbilldetail(proSellTrackingSerial, sellbillid);

-- Limit date ranges or add pagination
WHERE sellbilldate >= '2024-12-01' AND sellbilldate <= '2024-12-31';
```

### 2. **Memory Exhaustion**
**Issue**: PHP memory limit exceeded with large reports  
**Cause**: Loading too much data into memory at once

**Fix**:
```php
// Increase memory limit temporarily
ini_set('memory_limit', '512M');

// Or implement pagination
$limit = 1000;
$offset = $page * $limit;
$queryString .= " LIMIT $limit OFFSET $offset";
```

### 3. **Incorrect Discount Calculations**
**Issue**: Discount totals don't match expected values  
**Cause**: Mixed discount types or missing detail discounts

**Debug**:
```php
// Debug discount calculation
echo "Bill Discount: " . $sellbilldiscount . "<br>";
echo "Discount Type: " . $sellbilldiscounttype . "<br>";
echo "Detail Discount: " . $detaildiscount . "<br>";
echo "Total Before: " . $sellbilltotalbill . "<br>";
echo "Total After: " . $sellbillaftertotalbill . "<br>";
```

### 4. **Serial Number Filtering Issues**
**Issue**: Serial number search returns no results  
**Cause**: Case sensitivity or formatting issues

**Fix**:
```sql
-- Use case-insensitive search
WHERE UPPER(proSellTrackingSerial) = UPPER('SERIAL123');

-- Check for leading/trailing spaces
WHERE TRIM(proSellTrackingSerial) = 'SERIAL123';
```

---

## 🧪 Testing Scenarios

### Test Case 1: Multi-Report Generation
```
1. Select multiple report checkboxes (rep1, rep2, rep3)
2. Set date range and client filter
3. Submit form and verify all selected reports generate
4. Check that totals are calculated correctly across reports
5. Verify performance with large datasets
```

### Test Case 2: Serial Number Tracking
```
1. Create sales bills with specific product serial numbers
2. Search by serial number in advanced filter
3. Verify only bills containing that serial appear
4. Test with partial serial matches
5. Confirm case sensitivity handling
```

### Test Case 3: Performance Testing
```
1. Generate large dataset (1000+ bills)
2. Run reports with various filter combinations
3. Monitor query execution times
4. Test memory usage with large result sets
5. Verify batch loading optimization works
```

### Debug Mode Enable
```php
// Add at top of functions for debugging
echo "Memory Usage: " . memory_get_usage(true) / 1024 / 1024 . " MB<br>";
echo "Query String: " . $queryString . "<br>";
echo "Bill Count: " . count($sellbillData) . "<br>";

// Debug data processing
foreach ($sellbillData as $bill) {
    echo "Bill: " . $bill->sellbillid . " Total: " . $bill->sellbillaftertotalbill . "<br>";
}
```
