Restrict the deletion of attachment

[Tanya10]

Hi ,
I have a requirement to restrict deletion of attachment post submission of request for particular catalog item.
I followed this -https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0825743
It works well, but on portal even though attachment is not deleted it adds an additional comment saying deleted attachment

can you try Creating Fresh Table.None DELETE ACL on sys_attachment?

if user fails ACL then delete/cross icon won't be shown

Ensure none of the existing DELETE ACLs pass for sc_req_item

-> add this in condition of existing Table.None DELETE ACLs, so that they don't allow DELETE

-> in the new ACL you create, use this script

var gr = new GlideRecord("sc_req_item");
gr.addQuery("cat_item.name", "XYZ");
gr.addQuery('sys_id', current.table_sys_id);
gr.query();
answer = !gr.hasNext();

Hi @Ankur Bawiskar 
I did implement the same solution and added the condition on existing delete acl on attachment table but it doesn't work

@Tanya10 

try checking that widget and how it shows that cross icon

that will help you to restrict
