# Bulk Update

Bulk Update lets you modify specific fields across multiple rows (voyages, items, etc.) at once, saving time and reducing repetitive actions. Each list will show different fields for bulk updating. If no bulk-editable fields are configured for a particular list, an empty Bulk Update window will appear.

1\) Click on the **Bulk Update** button or hover a row an click the checkbox to select an instance. A highlighted **Bulk Update** button with the "x" icon indicates that you are in edit mode.

{% endtab %}
{% endtabs %}

5\) For each field, choose one of the following update options:

* **Keep Existing**: The field value will remain unchanged for all selected rows.
* **Set New Value**: Enter a new value that will be applied to the field across all selected rows.
* **Change by Percentage**: Enter a percentage to adjust the field’s value accordingly.
  * *Example*: If you enter **10**, a value of 5**0** will increase to **55**.
* **Change by Value**: Enter a number to add/subtract from the existing field value.
  * *Example*: If you enter **10**, a value of **50** will increase to **60**.

Once you've made your selections, click **Next** to preview the changes before applying them.
