Sorting by Month with timestamp data.

[#1]

I am new here, and also new with Qlikview.

I have a issue with sorting by months. I have a column called Closed which containt  Timestamp data.

I did use a format pattern for timestamp: MMMMMMMMMM-YYYY, as you can see below in the screenshot.

Now I want to sort it like this:

april-2013

maart-2013

etc...

How can I accomplish this? Thanks for your help.

Your listbox shows duplicates because the values are really still timestamps, just formatted as month-year. What I think you should do is create a new field in the script:

date(monthstart(Closed),'MMMM-YYYY') as MonthYear

This new field will be a date field with the start of the month as numeric value and formatted as monthname-year. You can sort that numerically in descending order to get the sorting you want.

Sorting seems to be ok. I think your problem is that you formatted the textual representation of your values like 'MMMM-YYYY', but you kept the underlying numeric timestamp values, thus keeping multiple values for your months in e.g. a list box (because of the distinct numeric values).

Create an additional list box expression

=num(Closed)

to see what I mean.

Try using something like

LOAD

     Date(Monthstart(Closed),'MMMM-YYYY') as MonthClosed,

     ....

when creating your month field from timestamp field.
