Week 2 Implementation Guide: Manufacturing (MRP) + Multi-Output BOM + Yield/Wastage

This guide explains what Odoo Community Edition already provides, what we built custom, and how to verify each feature.

Yield % / Wastage report per batch/lot ❌ Not supported ✅ c2c_yield_wastage
Auto-generate yield record on MO done ❌ Not supported ✅ c2c_yield_wastage

Step 0 — Initial Settings Configuration (For a Fresh Database)

If you are deploying this on a brand-new database, you must manually turn on these advanced Odoo features before the custom features will appear.

Turn on Manufacturing Features:

  1. Open the Manufacturing app.
  2. Go to Configuration > Settings.
  3. Under the Operations section, check the box for Work Orders.
  4. Click the purple Save button at the top left. (Note: If you do not do this, the "Work Centers" menu will remain completely hidden!)

Step 2.1 — Standard MRP Configuration

(Step 2.1.1) Create Work Centers

  1. Open Manufacturing app > Configuration > Work Centers.
  2. Click New and create the following 4 work centers for C2C Agricorp:
Work Center Company Cost per Hour
Cleaning Station C2C Agricorp India Pvt Ltd ₹150
Grading Table C2C Agricorp India Pvt Ltd ₹200
Packing Line C2C Agricorp India Pvt Ltd ₹250
Stringing Station C2C Agricorp India Pvt Ltd ₹180
  1. On each Work Center form, set the Costing Method to Time-based and set the Cost per Hour.

(Step 2.1.3) Set Standard Cost on Raw Materials

  1. Open Inventory > Products > Products.
  2. Open Raw Turmeric (or your flower product).
  3. Under the Purchase tab, verify the cost.
  4. Under General Information > Product Type: set to Storable Product.
  5. Go to Accounting tab > Costing Method: should read Standard Price.

Step 2.2 — Multi-Output BOM (c2c_multi_output_bom)

This custom module allows a single BOM to produce multiple finished products in one Manufacturing Order.

How to create a Multi-Output BOM (Example: Roses)

  1. Open Manufacturing > Products > Bills of Materials.
  2. Click New.
  3. Set:
    • Product: Pack 500g Roses (your primary/main output)
    • Quantity: 200
    • BOM Type: Manufacture This Product
  4. In the Components tab, add: Raw Roses | 100 kg.
  5. Click the Output Products tab (new custom tab).
  6. Click Add a line and add co-products:
Output Product Quantity Notes
Pack 500g Roses (Stems) 5 Byproduct stems
  1. Save the BOM.

How to run a Multi-Output Manufacturing Order

  1. Go to Manufacturing > Manufacturing Orders > New.
  2. Select the BOM you just created. The Additional Outputs tab will appear automatically with your co-products pre-filled.
  3. Set the Actual Qty for each output on the Additional Outputs tab.
  4. Assign Lot/Batch to each output line (for FEFO traceability).
  5. Click Mark as Done.
  6. ✅ Odoo will automatically create separate stock moves for EACH output product into your finished goods location.

Step 2.3 — Yield & Wastage (c2c_yield_wastage)

This module auto-generates a yield report every time a Manufacturing Order is marked as Done.

How Yield is Calculated

Input Qty  = Total raw materials consumed
Output Qty = Finished goods produced (what went to stock)
Wastage    = Input - Output
Yield %    = (Output / Input) × 100

How to View Yield Reports

  1. Go to Manufacturing > Reporting > Yield & Wastage (new menu).
  2. You will see a list of all completed MOs with their yield data.
  3. Colour coding:
    • 🔴 Red = Yield below 70% (critical — investigate)
    • 🟡 Yellow = Yield below 85% (warning — review process)
    • ✅ White = Yield 85% and above (acceptable)
  4. Click any record to open the form view with full detail, lot traceability, and a Notes field to record root cause.

Smart Button on MO

After marking an MO as Done, go back to the Manufacturing Order. A new Yield Reports smart button (bar chart icon) will appear in the top right of the MO form. Click it to jump directly to the yield data for that batch.

Step 2.4 — Manufacturing Cost Rollup

How to include labor/overhead in finished goods cost

  1. Open Manufacturing > Configuration > Work Centers.
  2. Open each work center. Set the Cost per Hour (labor rate).
  3. On the BOM, under the Operations tab, add:
    • Work Center: Grading Table
    • Duration: 30 minutes
  4. When the MO is completed, Odoo's mrp_account module (already installed) will post:
    • Raw material cost → Debit Work In Progress
    • Labor cost (time × rate) → Debit Work In Progress
    • On MO done: WIP transfers to Finished Goods at the rolled-up total cost.

Verify Cost Rollup

  1. Complete an MO for Pack 500g Roses.
  2. Go to the MO form > Click the Valuation smart button (if visible, requires Inventory Valuation enabled).
  3. Also check: Accounting > Journal Entries and filter by Manufacturing.

Verification Checklist — Week 2

  • Work Centers created (Cleaning, Grading, Packing, Stringing)
  • Multi-Output BOM created with Output Products tab visible
  • MO completes multi-output → verify 2+ stock moves created in Inventory > Transfers
  • Yield report auto-generated after MO completion
  • Yield & Wastage report visible in Manufacturing > Reporting
  • Color coding works — try an MO where output < 70% of input
  • Journal entries posted for raw cost + labor cost on MO completion

Example: Jasmine Stringing Flow

BOM Setup:

  • Primary Output: Bundle (3m) Jasmine — Qty: 20
  • Component: Raw Jasmine — 100 kg
  • Output Products tab: (none — single output, standard flow)
  • Operations: Stringing Station | 2 hours

Expected Results after MO Done:

  • 20 x Bundle (3m) Jasmine moved to Finished Goods ✅
  • Yield Report created: Input 100kg, Output ~60kg equivalent, Yield ~60% ✅
  • Journal Entry: Raw Material Cost + (2hr × ₹180) = Total COGS ✅
