🗄️ Database Tables

Primary Settlement Tables

🔑 Key Functions

1. Default Action / Settlement Form - Settlement Interface

Location: Line 121

Purpose: Display settlement creation form with employee and reference data

Process Flow:

1. Load employees with existing cash custody (bind)

2. Load available cash registers/safes

3. Load expense type categories

4. Load cost centers for project allocation

5. Display settlement creation form

Data Loading:

$binds = $bindEx->getAllEmployeeWithBind();        // Employees with cash custody
$save = $saveDAO->queryByConditions(0);            // Active cash registers
$expensesType = $expensesTypeDAO->queryByCondition(0); // Expense categories
$costCenter = $costCenterDAO->queryByCondation(0); // Cost centers

---

2. add() - Process Settlement Transactions

Location: Line 144

Purpose: Create multiple settlement transactions in a single group

Function Signature:

elseif ($_GET['do'] == "add")
// Processes: Multiple settlement lines in one transaction group

Process Flow:

1. Get iteration count and employee ID

2. Generate new group number for transaction set

3. Process each settlement line via add($i, $group)

4. Handle transaction completion and error management

Group Processing Logic:

$itr = filter_input(INPUT_POST, "itr");              // Number of settlement lines
$employeeId = filter_input(INPUT_POST, "employee");  // Employee being settled
$bindSettlement = $bindSettlementEx->getLastGroupNo($employeeId);
$group = $bindSettlement->groupno + 1;               // New group number

for ($i = 1; $i <= $itr; $i++) {
    add($i, $group);  // Process each settlement line
}

---

3. add($itr, $group) - Individual Settlement Processing

Location: Line 409

Purpose: Process individual settlement line item

Function Signature:

function add($itr, $group)

Process Flow:

1. Extract settlement parameters for line item

2. Determine settlement type (cash vs expense)

3. Create settlement record

4. Generate financial journal entry via saveDailyEntry()

Settlement Type Processing:

$bindSettlementType = filter_input(INPUT_POST, "bindSettlement" . $itr);

if ($bindSettlementType == 1) {
    // Cash settlement - return money to safe
    $bindSettlement->settlementwayid = $save;
    $id = $save;
} else {
    // Expense settlement - reimburse expense
    $bindSettlement->settlementwayid = $expensestype;
    $id = $expensestype;
}

---

4. saveDailyEntry() - Financial Accounting Integration

Location: Line 316

Purpose: Create comprehensive accounting entries for settlements

Function Signature:

function saveDailyEntry($value, $bindSettlementType, $employeeId, $id, 
                       $bindSettlementId, $project)

Accounting Logic:

1. Credit: Employee custody account (reduce employee cash)

2. Debit: Cash account (if cash return) OR Expense account (if expense)

3. Cost Center: Apply project allocation if specified

Journal Entry Structure:

// Credit: Employee custody account (always)
$employee = $employeeDAO->load($employeeId);
$custodyAccountName = 'عهدة ' . $employee->employeeName;  // "Custody of [Employee Name]"
$treeId3 = addTreeElement($custodyAccountName, 46, 3, 0, 1, '', 0, 0);

$dailyEntryCreditor->value = $value;
$dailyEntryCreditor->accountstreeid = $treeId3;

// Debit: Cash or expense account (depending on settlement type)
if ($bindSettlementType == 1) {
    // Cash return
    $mySave = $mySaveDAO->load($id);
    $treeId2 = $mySave->treeId; // Cash account
} else {
    // Expense reimbursement
    $expensesType = $expensesTypeDAO->load($id);
    $treeId2 = $expensesType->treeId; // Expense account
}

$dailyEntryDebtor->value = $value;
$dailyEntryDebtor->accountstreeid = $treeId2;

---

6. edit() - Settlement Modification

Location: Line 163

Purpose: Edit existing settlement group

Function Signature:

elseif ($_GET['do'] == "edit")
// Parameters: groupno, employeeid

Process Flow:

1. Load existing settlement records by group

2. Calculate current employee cash balance

3. Display edit form with current data

Balance Calculation:

// Calculate employee cash position
$bs = $bindEx->queryByEmployeeidAndDeleted($employeeId, 0);        // Total binds
$bSs = $bindSettlementEx->queryByEmployeeidAndDeleted($employeeId, 0); // Total settlements

$sumBind = 0;      // Total cash given to employee
$sumSettlement = 0; // Total cash settled by employee

foreach ($bs as $b) {
    if ($b->bindtype == 1) {
        $sumBind += $b->savevalue;  // External cash
    } else {
        $sumBind += $b->ckekvalue;  // Internal cash
    }
}

foreach ($bSs as $bS) {
    $sumSettlement += $bS->value;  // Settlement amounts
}

$sumNet = $sumBind - $sumSettlement; // Net cash position

---

🧮 Balance Calculation Methods

Employee Cash Balance Calculation

function calculateEmployeeBalance($employeeId) {
    // Get all cash custody records
    $binds = $bindEx->queryByEmployeeidAndDeleted($employeeId, 0);
    
    // Get all settlements (excluding current editing group)
    $settlements = $bindSettlementEx->queryByEmployeeidAndDeleted($employeeId, 0);
    
    // Calculate total cash given to employee
    $sumBind = 0;
    foreach ($binds as $bind) {
        if ($bind->bindtype == 1) {
            $sumBind += $bind->savevalue;  // External cash
        } else {
            $sumBind += $bind->ckekvalue; // Internal cash
        }
    }
    
    // Calculate total settlements
    $sumSettlement = 0;
    foreach ($settlements as $settlement) {
        $sumSettlement += $settlement->value;
    }
    
    // Net position (positive = employee owes company)
    $netBalance = $sumBind - $sumSettlement;
    
    return [
        'totalBind' => $sumBind,
        'totalSettlement' => $sumSettlement,
        'netBalance' => $netBalance
    ];
}

Settlement Group Management

function getNextGroupNumber($employeeId) {
    $lastSettlement = $bindSettlementEx->getLastGroupNo($employeeId);
    return ($lastSettlement->groupno ?? 0) + 1;
}

📊 Performance Considerations

Database Optimization

1. Critical Indexes:

- bindsettlement(employeeid, groupno, deleted)

- bind(employeeid, deleted)

- dailyentry(dailyentryid)

- employee(conditions)

2. Query Optimization:

- Efficient employee balance calculations

- Fast settlement group lookups

- Optimized chart of accounts queries

Balance Calculation Performance

• • Cache employee balance calculations
• • Use database aggregations where possible
• • Minimize loops in balance calculations

🐛 Common Issues & Troubleshooting

1. Balance Calculation Errors

Issue: Employee cash balances don't match expected amounts

Cause: Missing bind records or settlement transactions

Debug:

-- Verify employee cash custody records
SELECT 
    employeeid,
    bindtype,
    CASE WHEN bindtype = 1 THEN savevalue ELSE ckekvalue END as amount,
    deleted
FROM bind 
WHERE employeeid = [EMPLOYEE_ID]
ORDER BY id;

-- Check settlement completeness
SELECT 
    groupno,
    settlementway,
    value,
    deleted,
    dailyentryid
FROM bindsettlement 
WHERE employeeid = [EMPLOYEE_ID]
ORDER BY groupno, id;

2. Journal Entry Mismatches

Issue: Settlement journal entries don't balance

Cause: Incorrect account mapping or amount calculations

Debug:

-- Verify journal entry balance
SELECT 
    de.dailyentryid,
    SUM(ded.value) as total_debits,
    SUM(dec.value) as total_credits
FROM dailyentry de
LEFT JOIN dailyentrydebtor ded ON ded.dailyentryid = de.dailyentryid
LEFT JOIN dailyentrycreditor dec ON dec.dailyentryid = de.dailyentryid
WHERE de.dailyentryid IN (
    SELECT dailyentryid FROM bindsettlement 
    WHERE employeeid = [EMPLOYEE_ID]
)
GROUP BY de.dailyentryid
HAVING total_debits != total_credits;

3. Group Number Conflicts

Issue: Settlement group numbers not unique or sequential

Cause: Concurrent settlement processing

Solution:

• • Implement proper locking mechanism
• • Use database sequences for group numbers
• • Validate group uniqueness before creation
