Measure-group based Data Access Sets

Summary:

Oracle Supply Chain Planning: I am trying to create a Measure-group based data access set so that a specific job role will have read only access to a measure group, and write access to another measure group.

I tried this approach:

created a read-only data access set 1 at the Legal Entity level, and data access set 2 at the Measure group level, containing the measure that requires write access. Assigned both the data access set to the job role. Checked the "Enable Data Security checkbox"
