Sorting on Multiple Columns in Model
Hello Community,
I have a use case where I need to sort a data set first on column A and then, retaining this order, on column B. From what I gathered, the Sort node allows only one column at a time. Are there any methods?

Unfortunately the sorting dialogue currently only supports one level of sort.
Multilevel sort (sort by, and then by) is in development and will be delivered in a forthcoming release.
Hope that helps,
