I have an obj1 and field on it field1 and one profile Billing User.
When I click a Custom Button on obj1, it will check the field1 to true for all the profile. However, I want field1 such that it should read only from page layout but it edit from apex, only for Billing User Profile.
If we make field read only from Field Accessibility then this field will not update by apex. I want Field Editable by apex and read only for manually only for specific profile. (Note: I've 12 record type) how can I achieve this?
