📋 Bill of Materials (Advanced) - User Manual

Version 2.0 | ProductionPlannerPro

1. What's New in BOM Advanced?

New Features:

• 🔧 Material Categories - Separate Raw Materials, Packing Materials, and Labels
• ⏱️ Lead Time Tracking - Track procurement time for each material
• 📊 Availability Checking - Real-time stock availability analysis
• 🎯 Smart Recommendations - "You have X, need Y → Order Z"
• 📅 Production Planning - Calculate earliest start dates based on lead times
• 🔒 Material Allocation - Reserve materials for production orders

2. Material Categories Explained

2.1 Why Categories Matter

Organizing materials by category helps with:

• Better procurement planning (different suppliers for different categories)
• Accurate lead time tracking
• Clearer BOM organization
• Separate inventory management

2.2 The Three Categories

Category	Description	Examples
🔧 Raw Materials	Base materials for manufacturing	Wood planks, steel sheets, plastic pellets, fabric
📦 Packing Materials	Materials for packaging the finished product	Cardboard boxes, bubble wrap, tape, foam inserts
🏷️ Labels	Labels, stickers, tags	Product labels, barcode stickers, warning tags, care labels

3. Creating a BOM with Categories

Step 1: Create BOM Header

1. Click ➕ Create BOM
2. Enter BOM Code (e.g., BOM-CHAIR-001)
3. Enter BOM Name
4. Select Product from dropdown
5. Set version, output quantity, status
6. Click 💾 Create BOM

Step 2: Add Materials by Category

1. Click 👁️ View on your BOM
2. Select a category tab (Raw Materials / Packing Materials / Labels)
3. Choose material from dropdown
4. Enter quantity required
5. Enter wastage percentage (if applicable)
6. Enter lead time in days
7. Click ➕ Add to BOM
8. Repeat for all materials in that category
9. Switch tabs and add materials to other categories

4. Lead Time Management

4.1 What is Lead Time?

Lead time is the number of days between ordering a material and receiving it. This includes:

• Supplier processing time
• Manufacturing time (if custom)
• Shipping time
• Quality inspection time

4.2 Why Track Lead Times?

• Know when to order materials
• Calculate earliest production start date
• Plan production schedules accurately
• Avoid production delays

4.3 How Lead Times Affect Planning

5. Material Availability Checking

5.1 How It Works

1. Open a BOM
2. Enter "Quantity to Produce" (e.g., 100 units)
3. Click 🔍 Check Availability
4. System analyzes stock for all materials
5. Shows results with recommendations

5.2 Understanding the Results

Status	Meaning	Action Required
✅ Sufficient	Enough stock available	None - Ready to produce
⚠️ Partial	Some stock available, not enough	Order the shortage amount
❌ Insufficient	No stock or very low	Order full requirement

5.3 Smart Recommendations

The system provides actionable recommendations:

6. Reserved vs Available Stock

6.1 Stock Types Explained

• Current Stock: Total physical stock in warehouse
• Reserved Stock: Allocated to confirmed orders
• Available Stock: Current - Reserved = What you can actually use

6.2 Why This Matters

7. Production Planning Workflow

Step-by-Step Process:

1. Receive Sales Order: Customer orders 100 chairs
2. Check BOM: Open Wooden Chair BOM
3. Check Availability: Enter quantity 100, click Check
4. Review Results:
   • Oak Wood: Need to order 125 MTR (lead time: 7 days)
   • Screws: Sufficient
   • Foam: Need to order 20 PCS (lead time: 5 days)
   • Box: Need to order 50 PCS (lead time: 2 days)
5. Order Materials: Place orders with suppliers
6. Calculate Start Date: Max lead time = 7 days → Can start in 7 days
7. Schedule Production: Schedule for 7 days from now
8. Reserve Materials: System reserves materials when production order created
9. Start Production: All materials available, begin manufacturing

8. Material Allocation

8.1 What is Allocation?

Allocation = Reserving materials for a specific production order. This prevents:

• Double-booking materials
• Stockouts mid-production
• Production delays

8.2 How It Works

1. Create production order for 100 chairs
2. System automatically reserves materials based on BOM
3. Reserved stock = Previously reserved + New reservation
4. Available stock decreases
5. Other orders see reduced availability
6. When order completes/cancels, materials released

9. Best Practices

9.1 Material Categories

• Always organize materials by correct category
• Raw materials = things you transform
• Packing = things you add at the end
• Labels = things you stick on

9.2 Lead Times

• Be realistic - add buffer for delays
• Update lead times quarterly based on actual experience
• Track by supplier (different suppliers = different lead times)
• Include inspection time in lead time

9.3 Wastage

• Set wastage based on historical data
• Review and adjust monthly
• Higher wastage for cutting/machining operations
• Zero wastage for pre-packaged items

9.4 Availability Checking

• Always check before confirming orders to customers
• Check availability weekly for planned orders
• Order materials immediately when shortages identified
• Consider safety stock for critical materials

10. Troubleshooting

Issue: Materials don't show in category dropdown

Solution:

• Check material type matches category (raw materials for Raw Materials tab)
• Ensure materials are created and active
• Refresh the page

Issue: Availability shows "Insufficient" but I have stock

Solution:

• Check Available Stock not just Current Stock
• Stock may be reserved for other orders
• View material allocations to see what's reserved

Issue: Lead time calculation seems wrong

Solution:

• System uses maximum lead time across all materials
• Check individual material lead times
• Earliest start = Today + Max Lead Time

11. FAQs

Q: Can I move a material to different category after adding?

A: Yes! Delete the material from BOM and re-add it in the correct category tab.

Q: What happens if I don't set lead times?

A: System defaults to 0 days, meaning materials assumed immediately available. This may cause planning issues.

Q: How often should I check availability?

A: Best practice:

• Before confirming customer orders
• Weekly for upcoming production schedule
• After receiving new orders
• When planning material purchases

Q: Can the same material be in multiple categories?

A: Technically yes, but not recommended. Choose the most appropriate category.

Q: What's the difference between BOM and BOM Advanced?

A:

• BOM: Basic material list
• BOM Advanced: Categories + Lead times + Availability + Planning
