How to add serial number in the click of Preview Icon

[PrashantT]

Hi, 

I have one requirement where I have to add the serial number as well on the click of preview icon. This variable is created in the catalog item, and it is editable in the RITM.

Thanks

Hey @PrashantT  

Solution - 

• Go to the referenced table
  Navigate to any record in the Company table (core_company).
• Open Form Layout
  Right-click the form header -> Configure -> Form Layout.
• Create or select sys_popup view
  In the View name dropdown:
• If sys_popup exists, select it.
• If not, click New, name it sys_popup, and click OK.
• Add your custom field
  Use the layout editor to add your custom field (e.g., u_custom_field) to the sys_popup view.
• Save and test
  Save the layout. Go back to the Incident form, hover over the Company icon - your custom field should now appear in the popup!

Just go through below articles which sugest you to configure sys_pop view for your reference table.

Hi @PrashantT ,

To customize which fields appear in the reference field popup, you just need to configure the sys_popup view for the target table:
          Open the table with ?sysparm_view=sys_popup in the URL like below:

<your instance name>.service-now.com/<table name>.do?sysparm_view=sys_popup

            Add/remove the fields you want (e.g. Serial Number). Save the layout.

This way, whenever you click the preview icon, the popup will show the fields you defined in that view.

I also found a related discussion on the ServiceNow Community that you can refer to:

Solution:

1. Go to the form where you want to modify the preview, and open Configure → Form Layout from the context menu.

2. By default, you'll see the Default view, but you need to check if the sys_popup view exists.

• If it exists, you can add or remove fields as per your requirements.

• If it doesn’t exist, create a new view named "sys_popup".

Note: Make sure the view is named exactly sys_popup — not something like sys_popup,asset1. The preview functionality only works with the sys_popup view.

Refer to the attached screenshot for more details.

Added serial number to sys_popup view:
