Configuration:
  Prefix: LOT-%(year)s-
  
Generated (2024):
  LOT-2024-0000001

Troubleshooting Example

Issue: Wrong Format Generated

User Configuration:

Custom Lot/Serial: %(y)s%(month)s%(day)s

Expected Output:

2411200000001

Actual Output (Before Fix):

%(y)s%(month)s%(day)s0000001  ❌

Actual Output (After Fix v1.1.1):

2411200000001  ✓

Solution: Upgrade to version 1.1.1 or later


Best Practice Example

Good: Date-Only Format for Large Batches

Format: %(y)s%(month)s%(day)s
Batch: 5000 units
Result: All have same date (consistent)
Time: ~1 minute

2411200000001
2411200000002
...
2411205000000

Avoid: Time-Based Format for Large Batches

Format: %(y)s%(month)s%(day)s%(h24)s%(min)s
Batch: 5000 units
Problem: If generation takes > 1 minute, dates differ

24112014300000001  ← Started at 14:30
24112014300000002
...
24112014310002500  ← Crossed to 14:31
...
24112014320005000  ← Ended at 14:32

Result: Inconsistent timestamps within batch

Recommendation: Use date-only codes for large batches


Summary

These examples demonstrate:

Flexibility: Supports various industries and use cases ✓ Automation: No manual date updates needed ✓ Performance: Fast generation even for large quantities ✓ Traceability: Clear date identification in lot numbers ✓ Compliance: Meets regulatory requirements ✓ Scalability: Handles from 1 to 500,000+ units

The date format feature combined with batch optimization provides a powerful, efficient solution for modern manufacturing and warehouse operations.
