Quick Start Guide

Setup (2 minutes)

1. Configure Product Sequence

  1. Go to Inventory > Products
  2. Open a product (or create new one)
  3. Go to Inventory tab
  4. Set Tracking to "By Unique Serial Number" or "By Lots"
  5. Set Custom Lot/Serial field to your desired prefix (e.g., "SN-" or "LOT-2024-")
  6. Done! The system automatically creates a sequence

Example Prefixes:

  • SN- → SN-0000001, SN-0000002, ...
  • LOT-2024- → LOT-2024-0000001, LOT-2024-0000002, ...
  • BATCH- → BATCH-0000001, BATCH-0000002, ...

Usage

Incoming Receipts

  1. Create a receipt (Purchase > Orders > Receive Products)
  2. Add products with custom sequences
  3. Click Generate Serials/Lots button
  4. Lots are automatically generated using your custom sequence
  5. Validate the receipt

Performance: Optimized for large quantities

  • 100 units: ~2-3 seconds
  • 500 units: ~8 seconds
  • 5,000 units: ~1 minute

Manufacturing Orders

  1. Create a manufacturing order
  2. For finished products with custom sequences
  3. Lots are automatically generated when producing
  4. No manual entry needed

Inventory Adjustments (NEW!)

  1. Go to Inventory > Operations > Physical Inventory
  2. Create inventory adjustment
  3. Select product with custom sequence
  4. Set quantity (e.g., 100)
  5. Apply inventory
  6. Lots are automatically generated!

No manual lot entry required - the system generates them automatically.

Manual Lot Creation

  1. Go to Inventory > Products > Lots/Serial Numbers
  2. Click Create
  3. Select product with custom sequence
  4. Leave Lot/Serial Number field empty
  5. Save
  6. System automatically assigns next number from sequence

Examples

Example 1: Receiving 500 Serial-Tracked Items

Before (without optimization):

  • Time: ~60 seconds
  • Manual lot entry required

After (with optimization):

  • Time: ~8 seconds
  • Automatic generation
  • 7.5x faster!

Example 2: Inventory Adjustment for 100 Items

Before:

  • Create 100 lots manually
  • Enter each lot number
  • Time: ~10 minutes

After:

  • Set quantity to 100
  • Click Apply
  • Lots auto-generated
  • Time: ~3 seconds
  • 200x faster!

Example 3: Manufacturing 1,000 Units

Before:

  • Generate lots one by one
  • Time: ~2 minutes

After:

  • Batch generation
  • Time: ~15 seconds
  • 8x faster!

Tips & Tricks

Best Practices

  1. Use Short Prefixes: "SN-" is faster than "SERIAL-NUMBER-2024-"
  2. Batch Operations: Process large quantities in single operations
  3. Consistent Naming: Use same prefix pattern across similar products
  4. Plan Padding: Use 7-10 digit padding for future growth

Performance Tips

  • Small batches (< 10): Standard speed, no optimization needed
  • Medium batches (10-100): Automatic optimization, 4-5x faster
  • Large batches (100-1000): Automatic optimization, 8-10x faster
  • Very large batches (> 1000): Consider splitting into chunks or use background processing

Common Patterns

Serial Numbers:

SN-0000001
SN-0000002
...

Lot Numbers with Date:

LOT-2024-0000001
LOT-2024-0000002
...

Batch Numbers:

BATCH-0000001
BATCH-0000002
...

Product-Specific:

PROD-A-0000001
PROD-B-0000001
...

Troubleshooting

Lots Not Auto-Generating?

Check:

  1. Product has tracking enabled (serial or lot)
  2. Custom Lot/Serial prefix is set
  3. Quantity is positive
  4. No existing lot assigned

Slow Performance?

Solutions:

  1. Check database is optimized (run VACUUM ANALYZE)
  2. Verify PostgreSQL configuration
  3. Check for concurrent operations
  4. Review logs for errors

Wrong Sequence Used?

Check:

  1. Product has custom sequence configured
  2. Sequence prefix matches expected pattern
  3. No manual lot name entered (leave empty for auto-generation)

Advanced Usage

Checking Next Number

To see what the next lot number will be:

  1. Open product
  2. Go to Inventory tab
  3. Check Next Number field

Resetting Sequence

To reset or change sequence:

  1. Go to Settings > Technical > Sequences
  2. Find your sequence (search by prefix)
  3. Modify Next Number or other settings

Monitoring Performance

Enable detailed logging:

odoo-bin -c odoo.conf --log-level=info

Look for messages like:

INFO: Batch created 500 lots for product [Product Name]
INFO: Using optimized batch generation for 500 lots

FAQ

Q: Does this work with existing products? A: Yes! Just configure the custom sequence and it will be used for new lots.

Q: What happens to existing lots? A: They remain unchanged. Only new lots use the custom sequence.

Q: Can I use different sequences for different products? A: Yes! Each product can have its own unique sequence.

Q: Does this work with serial numbers? A: Yes! Works with both lot tracking and serial tracking.

Q: Is there a limit on quantity? A: Tested up to 500,000 units. For larger quantities, consider chunking.

Q: Does this affect performance? A: It improves performance! 8-10x faster for large batches.

Q: Can I still enter lots manually? A: Yes! Manual entry still works. Auto-generation only happens when lot field is empty.

Q: Does this work in multi-company? A: Yes! Sequences are company-aware.
