Resolve incorrect vacation premium and vacation days calculation in Aspel NOI by adjusting seniority tables and payroll period configuration settings.
The Vacation Premium Calculation Error in Aspel NOI
Aspel NOI is one of Mexico’s most widely used payroll systems. A frequent problem users face is incorrect vacation premium and vacation days calculation, especially after the Federal Labor Law (LFT) reform effective January 2023.
Prerequisites
- Aspel NOI version 10.0 or higher.
- Administrator access to the system.
- Updated seniority table with the 2023 LFT reform values.
Step-by-Step Solution
1. Update the Seniority Table
Navigate to: Configuration → Tables → Seniority (Vacations)
| Years of service | Vacation days (LFT 2023) |
|---|---|
| 1 | 12 |
| 2 | 14 |
| 3 | 16 |
| 4 | 18 |
| 5 | 20 |
| 6-7 | 22 |
| 8-9 | 24 |
| 10-11 | 26 |
The minimum vacation premium is 25% of the salary for vacation days (Art. 80 LFT).
2. Verify the Employee Start Date
- Access: Employee Catalog.
- Verify the “Start Date” field is correct.
3. Verify the Vacation Premium Concept
- Access: Payroll Concepts Catalog.
- Locate “Vacation Premium” and verify it is active with the correct formula.
4. Recalculate the Payroll
Navigate to: Processes → Payroll Calculation and recalculate the affected period.
Prevention
- Apply Aspel NOI updates immediately when available.
- Back up the database before modifying configuration tables.
- Verify the seniority table at the beginning of each fiscal year.
