Hi @tabrez ahmed ,

You either need to use an ACL in combination with "glide.security.strict.updates" property or create a business rule that will check the user's role and reset the value of your field.

System Definition > Templates application module is restricted by role "admin".

This is Out-of-Box.

You can modify the module definition to allow one of the roles you're giving to also access that module (you'll also have to modify the base application "System Definition" to add that role as well, or the Application itself won't be visible).

However, I don't recommend the modification, as you may then have upgrade issues later on...as that Application module will be skipped in future upgrades.

Mark my answer correct & Helpful, if Applicable.

Thanks,
Sandeep
