# Dynamic Expiry Date Calculation for Proposed Standard Change Records

For normal change records, selecting the **Propose for Standard** checkbox automatically calculates the **Expiry Date** from the **Log Time** for changes created with past dates, or from the **Planned End Date** for changes created with future dates.

The **Expiry Date** is dynamically updated to ensure that the proposed standard change remains valid and complies with change management policies.

### Expiry Date Calculation Rules

- [Initial Expiry Date Calculation](/apex/docs/dynamic-expiry-date-validation#rule-1-initial-expiry-date-calculation)
- [Planned End Date Update](/apex/docs/dynamic-expiry-date-validation#rule-2-planned-end-date-update)
- [Past Planned End Date](/apex/docs/dynamic-expiry-date-validation#rule-3-planned-end-date-in-the-past)

#### Rule 1: Initial Expiry Date Calculation

When a user converts a normal change** record to a Standard Change Record using the **Propose for Standard** checkbox, then:

- The change record displays the **Expiry Date** field and is automatically populated based on **Log Time**.
- The system calculates the earliest Expiry Date as:
- `Log Time + 90 Days`
- Users can change the Expiry Date up to:
- `Log Time + 3 Years`

#### Rule 2: Planned End Date Update

When the user updates **Planned End Date** greater than the current Log Time:

- The system automatically recalculates the Expiry Date as:
- `Planned End Date + 90 Days`
- The updated Expiry Date reflects the new **Planned End Date** value.

#### Rule 3: Planned End Date in the Past

When the **Planned End Date** is earlier than the current Log Time:

- The system ignores the Planned End Date for Expiry Date calculation.
- The system recalculates the Expiry Date based on Log Time as:
- `Log Time + 90 Days`

This ensures that the Expiry Date always remains a valid future date.

### Expiry Date Functionality Based on Log Time and Planned End Date

To verify the Expiry Date functionality, perform the following steps:

1. Log in to the application as an Analyst (change manager).
2. Navigate to **Change > User > New Change Record**. The application displays the **Change Record Details** page.
3. Select **Minor** and Change Type as **Normal** record. You can see an option to change this to Standard. Convert this change to Standard using **Propose for Standard Change** checkbox.
4. Select the **Propose for Standard** checkbox. The following changes automatically occurs:
  - The **Expiry Date** is automatically populated as `Log Time + 90 Days`. This calculation happens immediately after selecting the **Propose for Standard** checkbox.
  - Users can change the Expiry Date up to **3 years from the Log Time**. ![Figure: Expiry Date based on Log Time](https://cdn.document360.io/62351b42-cfbd-43ad-8ce1-82b8f455337f/Images/Documentation/dynamic-expiry-date-validation-image-kqr8sw3y.png?sv=2026-02-06&spr=https&st=2026-11-07T16%3A12%3A07Z&se=2026-11-07T17%3A12%3A07Z&sr=c&sp=r&sig=2iy1p0tWpD0CbKZfmfqLAT7FtWEo6LstRwGD4XF4gc0%3D)Figure: Expiry Date
5. Update the **Planned End Date** to a future date. The system automatically recalculates the expiry date.
  - The system automatically recalculates the **Expiry Date** as:
  - `Planned End Date + 90 Days`

6. Update the **Planned End Date** to a date earlier than the current Log Time.
  - The system automatically recalculates the **Expiry Date** as:
  - `Log Time + 90 Days`
  - The past Planned End Date is not considered for Expiry Date calculation. ![Figure: Expiry Date past planned date](https://cdn.document360.io/62351b42-cfbd-43ad-8ce1-82b8f455337f/Images/Documentation/dynamic-expiry-date-validation-image-zyc1mmwr.png?sv=2026-02-06&spr=https&st=2026-11-07T16%3A12%3A07Z&se=2026-11-07T17%3A12%3A07Z&sr=c&sp=r&sig=2iy1p0tWpD0CbKZfmfqLAT7FtWEo6LstRwGD4XF4gc0%3D) Figure: Expiry Date past planned date
