I have upgraded our sandbox to Dynamics 365 and have enabled editable grids for my Opportunity entity. I was expecting field security to persist in the editable grid, but I AM able to edit fields that need to remain read only.
For example, we have a workflow that auto-populates the Topic field on the opportunity using information from several other fields. The field is set to read-only, but in the editable grid, I AM able to change the Topic.
Why is this? What can I do to keep the field read-only?
