The **Sequence dimension** is a special system dimension used to describe abstract steps or "periods after time." It's commonly used in models where events unfold relative to a time value, such as **depreciation models**, **efficiency curves**, or **growth timelines**.

Rather than using calendar-based time (like years or months), the Sequence dimension allows you to model concepts like “Year 0”, “Year 1”, … “Year 9”, representing steps from a starting point.

## Default behavior

By default, the system generates a Sequence dimension with values ranging from **0 to 9**, which fits most use cases on a yearly level.

However, for more complex models, especially those working on a **monthly basis** or requiring longer timelines, this range may not be sufficient. In those cases, the maximum number of sequence values must be extended.

## How to extend the sequence dimension **FOR ADMINS-ONLY**

To extend the number of generated Sequence dimension values, follow the steps below.

1. Click the **⚙️ cog icon** in the left-hand side navigation bar to open the Admin UI
2. In the Admin UI, go to **Projects**
3. Select the desired project from the list on the left
4. Below the project’s information on the right, click the **Settings button**
5. Scroll to or search for the **Dimensions** section
6. Locate the field:
   `featureFlags.sequenceDimensionAutoGeneratedMax`
7. Enter the new maximum number of steps (e.g., 120 for 10 years of monthly steps)

## When the change takes effect

The change to the Sequence dimension **only takes effect after a re-upload** of the data source that contains the `SEQ_DIM`table. This is usually the **first data source** in your project.

After upload, the sequence values will regenerate according to the new maximum.

## Important considerations

* **Changing the max value affects how sequence level values are formatted.**
  The Sequence dimension uses **fixed-width level values**, and the number of leading spaces depends on the maximum.

  For example:

  * Max = 99 → first value = `"<space>0"`
  * Max = 999 → first value = `"<space><space>0"`
* **Entering sequence values manually in Excel:**
  Use single quotes to preserve leading spaces (e.g. `‘<space><space>0`)
* **Existing models may need adjustments:**
  If models use the `TIMELAG()` function or reference specific sequence values, these **may need to be updated** to reflect the new value format.
