Hi Everyone,

When I copy a iist from one list and make changes to new list it is affecting in original list. Is it a feature from servicenow or any glitch ??

Please provide information on this.

Hi,

This is actually expected behavior in ServiceNow, not a glitch.

When you “copy” a list (for example via filter breadcrumbs or list URL), you’re not creating a completely independent list — you’re still working on the same underlying table and filter definition. So any changes you make (like modifying filters, columns, or views) can reflect back because they are tied to the same configuration.

Why this happens

• List layouts (columns, filters, etc.) are often user preferences or shared configurations
• Copying a list does not duplicate the configuration, it just reuses it
• So changes can appear in both places

---

How to avoid this

1. Save as a separate filter

Instead of reusing the same list:

• Use Save → Save As
• Give it a new name
  This ensures your filter is independent

2. Use a different view

If column changes are affecting both:

• Create or switch to a different view
• Configure columns there

3. Check if it’s a shared list

Sometimes lists are shared across users/roles, so changes are reflected globally
