# Maximum Inspection Interval Displayed as 0

In certain cases, the MII **(Maximum Inspection Interval)** in the **Calculation Summary** displays as **0**, preventing visibility of the correct inspection planning data. This can interfere with compliance tracking and scheduling accuracy.

To resolve this issue and display the correct MII and Next Inspection Date:

1. **Final Approve the Corrosion Schedule**
  - Ensure the corrosion schedule is fully approved in the system before proceeding.
2. **Edit the Corrosion Schedule**
  - Open the corrosion schedule for editing.
3. **Update the User Interval**
  - Replace the existing User Interval with the **Calculated Interval** shown in the system.
  - This value is typically found in the “Time Interval (Calculated)” section.
4. **Enable “Exceed Max”**
  - If prompted, check the box labeled **“Exceed Max”** to allow the new interval to override the default maximum.
5. **Save and Confirm**
  - After saving, the **MII in the Calculation Summary** will update from **0** to the new interval value.

Once completed, the system will correctly display:

- **Next Inspection Date** based on the updated interval
- **MII** reflecting the calculated value instead of zero

### Note that:

- This workaround is intended as a temporary solution until a permanent fix is implemented.
- Always document the change and rationale in the schedule notes for traceability.
- If unsure about the calculated interval, consult the RBI analysis or contact the corrosion engineering team.
