I believe that, when working in JIra on-prem, if you set a field configuration scheme for a project any JQL searches created with the project would be limited to the fields within the project field configuration. In other words, they would not see EVERY field in Jira.
In Jira cloud, I am not able to make this happen. I have several projects that have a specific set of fields. When they create a JQL search, they only want to see the fields used by their projects, not every field ever created in Jira.
Can this be done in JIra Cloud?
