Hi Rajesh,

Based on what I just tested, I don't think you need to worry about read-only fields (as long as they are read-only based on ACL or dictionary attribute.) UI policy is a different scenario.

I just created a template on the incident field as an ITIL user (Beth Anglin). I tried to set the number field to "BETH". Since the number field is read-only, it would not apply the template. I got the error seen below.

If someone tries to do something they shouldn't through a template, it does not let them.
