Restrict portal users from changing fields to display

Hello Tyler, 

1. Create Replacing View Model and choose the Parent Object - "PortalCaseSection"

2. Add next code to this schema:

define("PortalCaseSection", [], function() {

  return {

    entitySchemaName: "Case",

    details: /**SCHEMA_DETAILS*/{}/**SCHEMA_DETAILS*/,

    diff: /**SCHEMA_DIFF*/[

        {

             "operation": "remove",

        "name": "SeparateModeViewOptionsButton"

        }

    ]/**SCHEMA_DIFF*/,

    methods: {}

    };

});

3. As a result, "View" button option will be hidden for Portal Users: 

Best Regards,
