In this Interactive Grid, the SAL column is part of the query, but is not included in the Primary report.
So in the Grid View it is not shown, as expected. However, if you switch to Single Row View (in the hamburger menu of a row) then the SAL column is shown.
The SAL column can be hidden, but the user has to manually select Displayed Columns from the Setting menu to do that.
Why that would be needed, or why the Displayed Columns option even exists, is a mystery to me; I (read: the developer) didn't include the column for a reason, so why is the user able to overrule that?
I would list this as a bug, but this was already present in 23.1 (and probably earlier), so maybe it is a feature...
Maybe fixable using the
interactiveGrid and/or
recordView Jquery widget; the
showExcludeHiddenFields option of the latter looks promising.
