Expression to find last non NULL value in Field regardless of current selection

[Anonymous]

Hi Qlik Community

I am trying to create an expression to find the last non NULL value in a Field regardless of any current selection.

Using the following sample data, my objective is to identify the relevant Month with the desired results being :-

Used A - 1/05/2017     Used B - 1/06/2017     Used C - 1/07/2017

The example expression

=Max({<[Used C]={"<>ISNULL()"}>} Month)

is correct where Month is not a current selection however as soon as a selection is made for Month the results are by their nature limited to that selection and not what I am looking for. I have not yet discovered the strategic placement of "{1}" if that is the solution.

Any enlightenment would be greatly appreciated.

Thanks

Brian

=Max({<[Used C]={"<>ISNULL()"},Month=>} Month)

Note : = sign at the end is optional
