How to add atachment to catalog item description

[Arundhati]

Hello Everyone,

I have added an PPT to the catalog item description as a clickable link but it is only downloaded by the ITIL users and customers cannot download it how to make it also accessible to Customers?

Currently I have attached the ppt to sys_attachment and accessing it using sys_id in the description

Hello @Arundhati 

As per ServiceNow's KB Article: https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1830507 you need to create ACL for customer role like snc_external or any other role which differentiate between a customer and itil user.
