===== 🛋️ Madrid Sofa: BOM Simulation & Setup =====

This guide simulates how to fully define and structure a **Madrid Sofa** in CushionsERP using raw materials, sub-assemblies, and final BOMs.

----

==== 🛠️ 1. Define Raw Materials ====

These are the **lowest-level components** used in manufacturing (e.g., foam, fabric, zippers).

📍 Navigate to: **Products/Services → New Product**

🆕 Create entries like:
  * 🧽 HR Foam 40D – Seat  
  * 🧵 Fabric – Outdoor Grade A  
  * 🪡 Polyester Thread  
  * 🔗 Zipper YKK 60cm  
  * 📏 Velcro Tape  
  * 🛍️ Plastic Bag (Rain Cover)  

For each item, configure:
  * 🏷️ **Type**: Product  
  * 🛒 **Nature**: Purchasable  
  * 📦 **Stock management**: Enabled  
  * 📐 **Unit**: e.g., meters, pcs, kg

> 🧮 *Tip: Reflect material loss directly in BOM quantities — for example, add 5% extra to account for waste.*

----

==== ✅ 2. Define Sub-Assemblies (Components) ====

These are intermediate items assembled from raw materials:

  * Mattress Cushion  
  * Back Cushion  
  * Pillow  
  * Rain Cover

For each:

  * **Type**: Product  
  * **Nature**: Manufacturable  
  * **Stock Management**: Enabled  
  * **Assign a BOM** (see Step 4)

----

==== ✅ 3. Define the Finished Good ====

Create product: **Madrid Sofa**

  * **Type**: Product  
  * **Nature**: Manufacturable  
  * **Stock**: Managed  
  * **Selling**: Enabled (if sold directly)  
  * **Unit**: pcs

----

==== ✅ 4. Create BOMs ====

Go to: **MRP → Bill of Materials**  
Create a new BOM for each manufacturable item.

^ 📌 BOM A: Mattress Cushion ^ Quantity ^
| HR Foam 40D – Seat        | 2 pcs |
| Fabric – Outdoor          | 3 m   |
| Polyester Thread          | 50 m  |
| Zipper YKK 60cm           | 2 pcs |
| *Apply 5–10% loss if needed manually* | |

^ 📌 BOM B: Back Cushion ^ Quantity ^
| HR Foam 40D – Back        | 1 pcs |
| Fabric – Outdoor          | 2 m   |
| Polyester Thread          | 30 m  |

^ 📌 BOM C: Rain Cover ^ Quantity ^
| Plastic Bag              | 1 pcs |
| Velcro Tape             | 2 m   |
| Thread                  | 10 m  |

^ 📌 BOM D: Madrid Sofa (Final Assembly) ^ Quantity ^
| Mattress Cushion         | 1     |
| Back Cushion             | 1     |
| Pillow                  | 2     |
| Rain Cover              | 1     |

> 🔁 CushionsERP supports **multi-level BOMs** by referencing component BOMs in the final product's BOM.

==== ✅ 5. (Optional) Add Suppliers & Prices ====

For each raw material:

  * Go to **Product → Suppliers**
  * Add:
    * Supplier reference
    * Purchase price
    * Minimum quantity or delay (optional)

----

==== ✅ 6. (Optional) Create Manufacturing Order ====

Once BOMs are created:

  * Go to **Manufacturing → New Order**
  * Select **Madrid Sofa**
  * System calculates all components recursively
  * Execute the MO to deduct materials and add finished stock

----

==== ✅ Summary: Structure Modeled ====

  * 🧱 **Raw Materials** → Stock-managed, purchased  
  * 🧩 **Sub-Assemblies** → Each with its own BOM  
  * 🛋️ **Finished Good** → Final BOM uses subcomponents  
  * 💰 *Optional*: Supplier pricing, inventory links
