The system automatically creates a sequence +6. Check **Next Number** field to preview the format + +### Method 2: Via Sequence Configuration + +1. Go to **Settings > Technical > Sequences & Identifiers > Sequences** +2. Find or create a sequence with code `stock.lot.serial` +3. Set **Prefix** to your format (e.g., `LOT-%(year)s-%(month)s-%(day)s-`) +4. Set **Padding** (e.g., 7 for 7-digit numbers) +5. Assign this sequence to your product's `lot_sequence_id` field + +## How It Works + +### Date Interpolation Process + +``` +1. User configures: %(y)s%(month)s%(day)s + ↓ +2.

Choose Appropriate Granularity + +**Daily Batches**: Use `%(y)s%(month)s%(day)s` +- New sequence each day +- Good for daily production runs + +**Monthly Batches**: Use `%(year)s-%(month)s-` +- New sequence each month +- Good for monthly inventory cycles + +**Yearly Batches**: Use `%(year)s-` +- New sequence each year +- Good for annual product lines + +### 2.

Human Readability vs Compactness + +**Compact** (machine-friendly): +``` +%(y)s%(month)s%(day)s → 2411200000001 +``` + +**Readable** (human-friendly): +``` +LOT-%(year)s-%(month)s-%(day)s- → LOT-2024-11-20-0000001 +``` + +### 4. Avoid Time-Based Codes for Large Batches + +**Not Recommended**: +``` +%(y)s%(month)s%(day)s%(h24)s%(min)s +``` + +**Why**: If batch generation takes > 1 minute, lots might have different timestamps, causing confusion. + +**Better**: Use date-only codes for consistency within batches. + +## Testing Date Formats + +### Quick Test + +1.
