Hi , I have a model driven application.
It has 2 security roles - Administrator and Investigator
Item1:
There is a view called All Cases
In that view , Admin should be able to see the values in column "A"
In that view , Investigator should not be able to see the values in column "A"
Person with security Role : Administrator , able to see values in column "A"

Person with security Role : Investigator , not able to see values in column "A"

Item 2:
When I open the case, The field A should be editable by person having either Administrator security role or Investigator security role

I tried field Level Security I was able to achieve the first item but not second , can someone please help.

If I use the above , in views the value becomes empty , and when I open the case I am able to edit but not see the value
I want it empty in Views and be visible when I open the case , Is that a possibility ?
Please let me know.
