Which ACL is needed for sc_req_item.order_guide field?

[snow_beginner]

Hi,

I have a requirement that the field 'order guide' on sc_req_item should be read only unless the person has the role catalog_admin or is admin.

I have created a write and read ACL for this requirement.

I then created a test user and just gave it catalog_admin role but when I impersonate this user and check the form I can see the entire form is read only for me. As admin it's fine. 

There are also lots of ACL on this sc_req_item table. Do I need the create ACL too?
