ALL FEATURES OPERATIONAL!** --- Here are 4 comprehensive markdown documentation files for your Logistics OMS system. These files provide complete architectural specifications and can be directly used with Cursor: ### 1. `Order-Creation-System.md` ```markdown # Order Creation System ## Overview Excel-like grid interface for creating orders with real-time calculations and supplier integration. ```mermaid graph TD A[Order Grid] --> B[Item Entry] B --> C[Price Handling] B --> D[Supplier Assignment] C --> E[Carrying Charge Calculation] D --> F[Payment Type Selection] E --> G[Container Pre-plan] ``` ## Business Logic ### Price Handling ```javascript function handlePrice(item) { if (item.knownPrice) return item.price; // AI-powered estimation return ( historicalData[item.code].avgPrice * (1 + marketTrends[item.category]) ); } ``` ### Carrying Charge Calculation ```typescript const calculateCarryingCharge = ( basis: 'carton' | 'cbm' | 'weight', rate: number, item: OrderItem ) => { switch(basis) { case 'carton': return rate * item.cartons; case 'cbm': return rate * (item.unitCbm * item.cartons); case 'weight': return rate * (item.unitWeight * item.cartons); } }; ``` ### Payment Type Handling ```typescript enum PaymentType { CLIENT_DIRECT = 'Client Paid Factory', THROUGH_ME = 'Payment Through Me' } const paymentFlow = (type: PaymentType) => { if (type === PaymentType.CLIENT_DIRECT) { system.trackStatus('Factory Payment Pending'); } else { system.initiatePaymentProcess(); } }; ``` ## UI Components ```tsx ``` ## Integration Points - Supplier API for real-time capacity checks - Historical price database - Market rate monitoring service - Currency exchange API ## Edge Cases - **Unknown Prices**: Auto-estimate using similar items - **Mixed Payment Types**: Handle per-item payment flows - **Unit Conversion**: Automatic kg/lb conversion - **Bulk Discounts**: Apply tiered pricing automatically ``` ### 2. `Warehouse-LoopBack-System.md` ```markdown # Warehouse Planning & Loop-Back System ## Overview Automated handling of real-world logistics scenarios including shortages, damages, and quality issues. ```mermaid sequenceDiagram Warehouse->> System: Received Items System->> QC: Trigger Inspection alt All Items OK QC->> System: Approve for Container else Partial Shortage QC->> System: Report Shortage System->> LoopBack: Create New Order LoopBack->> Stage1: Add Missing Items else Quality Issues QC->> System: Flag Defects System->> LoopBack: Create Replacement Order end System->> Container: Update Allocation ``` ## Key Algorithms ### Shortage Handling ```typescript class LoopBackService { static handleShortage(originalOrder, item, shortageQty, reason) { const newOrder = { ...originalOrder, items: [{ ...item, quantity: shortageQty, loopBackReason: reason }], parentOrderId: originalOrder.id }; // Apply business rules if (reason === 'DAMAGE') { newOrder.priority = 'HIGH'; newOrder.deadline = Date.now() + 7*86400000; } return newOrder; } } ``` ### Container Allocation Logic ```javascript function optimizeContainerAllocation(items, containers) { const allocationPlan = []; let remainingItems = [...items]; containers.forEach(container => { const containerLoad = { container, items: [] }; let remainingCapacity = container.maxCbm; // Prioritize complete client orders remainingItems = remainingItems.filter(item => { const itemCbm = item.unitCbm * item.quantity; if (itemCbm <= remainingCapacity) { containerLoad.items.push(item); remainingCapacity -= itemCbm; return false; // remove from remaining } return true; }); // Handle partial allocations remainingItems.forEach(item => { const maxQty = Math.floor(remainingCapacity / item.unitCbm); if (maxQty > 0) { const partialItem = {...item, quantity: maxQty}; containerLoad.items.push(partialItem); remainingCapacity -= maxQty * item.unitCbm; // Create shortage record LoopBackService.handleShortage( item.order, item, item.quantity - maxQty, 'PARTIAL_ALLOCATION' ); } }); allocationPlan.push(containerLoad); }); return allocationPlan; } ``` ## UI Components ```tsx { if (result.status === 'FAILED') { loopback.createReplacementOrder(result); } }} /> { if (newQty < item.receivedQty) { loopback.handleShortage(item, item.receivedQty - newQty); } }} /> ``` ## Integration Points - Inventory management system - Quality control databases - Supplier notification APIs - Container optimization engine ## Edge Cases - **Partial Deliveries**: Auto-create loop-back orders - **Last-Minute Changes**: Real-time container reallocation - **Multi-Client Items**: Split allocation with priority - **Capacity Limits**: Warn when exceeding container limits ``` ### 3. `Container-Financials.md` ```markdown # Container Management & Financial System ## Core Architecture ```mermaid classDiagram class Container { +string realContainerId +string clientFacingId +string billNo +string sealNo +Charge[] charges +Milestone[] milestones +calculateProfit() number } class Charge { +string name +string type +number value +string currency } class FinancialEngine { +calculateCarryingCharge() number +allocateCharges() ChargeAllocation[] +calculateProfit() ProfitReport } Container "1" --> "*" Charge FinancialEngine --> Container ``` ## Financial Logic ### Charge Allocation ```typescript const allocateCharges = (container, clients) => { const totalCbm = clients.reduce((sum, client) => sum + client.cbmShare, 0); return clients.map(client => { const allocationRatio = client.cbmShare / totalCbm; return { clientId: client.id, charges: container.charges.map(charge => ({ ...charge, allocatedValue: charge.value * allocationRatio })) }; }); }; ``` ### Profit Calculation ```typescript class ProfitCalculator { static calculate(container) { const revenue = container.carryingCharges; const costs = container.charges.reduce((total, charge) => { const valueINR = charge.currency === 'USD' ? charge.value * exchangeRate : charge.value; return total + valueINR; }, 0); return { grossProfit: revenue - costs, margin: ((revenue - costs) / revenue) * 100 }; } } ``` ### Container Identification System ```typescript class ContainerMapper { private map = new Map(); createClientFriendlyId(realId: string): string { const clientId = `SHIP-${Math.random().toString(36).substr(2, 8).toUpperCase()}`; this.map.set(clientId, realId); return clientId; } } ``` ## UI Components ### Client View ```tsx ``` ### Admin View ```tsx ``` ## Charge Structure | Charge Name | Type | Value | Currency | |---------------------------|------------|------------|----------| | Duty GST | Percentage | 18% | INR | | Clearing Charges | Fixed | ₹2,500 | INR | | Unloading Charges | Weight-based | ₹50/kg | INR | | Miscellaneous | Fixed | ₹1,200 | INR | | Container Marine Insurance| Fixed | $50 | USD | | Container Freight | Fixed | $2,950 | USD | | Telex Charges | Fixed | $75 | USD | ## Edge Cases - **Currency Fluctuations**: Lock exchange rates at order creation - **Shared Costs**: Prorate container charges between clients - **Partial Shipments**: Adjust carrying charges proportionally - **Payment Disputes**: Freeze container until resolution ``` ### 4. `Security-User-Roles.md` ```markdown # Security & User Role Management ## Role-Based Access Matrix | Permission | Admin | Staff | Client | |---------------------|-------|-------|--------| | View all orders | ✓ | ✓ | ✗ | | Edit financials | ✓ | ✗ | ✗ | | View profits | ✓ | ✗ | ✗ | | Create users | ✓ | ✗ | ✗ | | Edit own orders | ✓ | ✓ | ✗ | | View container IDs | ✓ | ✓ | Masked | | Initiate loop-backs | ✓ | ✓ | ✗ | | View all clients | ✓ | ✓ | ✗ | ## Data Isolation Architecture ```mermaid sequenceDiagram User->>API: Request /orders API->>Auth: Verify token Auth->>API: Return user roles alt Client User API->>Database: SELECT * FROM orders WHERE client_id = {user.clientId} else Staff User API->>Database: SELECT * FROM orders API->>Data: Mask financial fields else Admin API->>Database: SELECT * FROM orders end API->>User: Return filtered data ``` ## Implementation Code ### Authentication Middleware ```typescript app.use('/api', (req, res, next) => { const token = req.headers.authorization; const user = authService.verifyToken(token); if (!user) return res.status(401).send(); // Attach user to request req.user = user; next(); }); ``` ### Data Filtering ```typescript // Row-Level Security Middleware app.use('/api/orders', (req, res, next) => { if (req.user.role === 'client') { req.query.clientId = req.user.clientId; } next(); }); // Field Masking Transformer const maskFinancials = (data, user) => { if (user.role !== 'admin') { return data.map(item => ({ ...item, unitCost: undefined, profitMargin: undefined, supplierPrice: undefined })); } return data; }; ``` ### Container ID Masking ```typescript class ContainerService { getContainer(id, user) { const container = db.getContainer(id); if (user.role === 'client') { return { ...container, realContainerId: undefined, clientFacingId: containerMapper.getClientFacingId(container.realContainerId) }; } return container; } } ``` ## Audit Trail System ```typescript class AuditLogger { static log(action: string, user: User, details: object) { db.create('audit_logs', { timestamp: new Date(), action, userId: user.id, ip: request.ip, userAgent: request.headers['user-agent'], details: JSON.stringify(details) }); } } // Usage AuditLogger.log( 'LOOPBACK_CREATED', currentUser, { originalOrder: 'ORD-1001', newOrder: 'LOOP-2837' } ); ``` ## Security Features - JWT authentication with 30-minute expiration - Role-based access control at API endpoint level - Financial data masking middleware - Container ID anonymization for clients - Complete audit trails for all operations - HTTPS enforcement - Rate limiting (100 requests/min) - IP whitelisting for admin access ## Edge Cases - **Permission Conflicts**: Deny access with explanation - **Data Leak Prevention**: Double-check client isolation - **Session Hijacking**: Automatic token invalidation - **Concurrent Edits**: Optimistic locking for records ``` These markdown files provide complete specifications for your Logistics OMS system: 1. **Order Creation System** - Excel-like grid with payment handling 2. **Warehouse & Loop-Back** - Automated shortage handling 3. **Container Financials** - Charge allocation and profit calculation 4. **Security & Roles** - Data isolation and access control Each file includes: - Visual diagrams using Mermaid - Core business logic in TypeScript/JavaScript - UI component specifications - Integration points - Edge case handling - Security implementations To use with Cursor: 1.
