The rows of a subject are fetched once and kept for as long as the connection lasts, so data changed on the platform afterwards is not on screen by itself. It is fetched again as follows: - Choose "Refresh" on the bar under the list, or "Refresh" in the "Edit" menu. - The rows of the subject on screen are fetched again from the platform. Only the subject on screen is refreshed. Changing the company in the toolbar builds the whole tree again and therefore refreshes everything. See [[Caching]].
