Let say we have a Doctype which has 5 fields(Name, phone, city, pin, state) and we have two users, first is administrator(System Manager) and a VRM. Now we can see all 5 fields of the Doctype when administrator is logged in but when VRM logs in he is only seeing 3 fields(Name, city, pin) even he has the read access for this particular Doctype. What can be the cause of this issue.
This is generally due to perm levels.
Unlike role permission, perm level is assigned at the field level meaning different roles can either view or edit the field, and can also be used to hide information from certain roles.
