NPrinting doesn't apply evaluate filter

One of my filters I use in NPrinting does not work. Either the table that should be produced is absent (very wrong expression I guess) or the table is present, but this one filter has not been applied.

I try to set the filter with the "evaluate" option. I tried a lot of different expressions, but none of them is working.

The table in QlikView (12.20.20400.0)

The table on which the filter should apply is a table with just 4 values, all dates. 3 of them are loaded from an excel-file, one (the one I'm trying to filter) is generated from the script bij the statement vLastPreviousMonthDay=Date(MonthEnd(Today(),-1),'DD-MM-YYYY') and then added tot the table with $(vLastPreviousMonthDay)

The filter in NPrinting (February 2018 SR1)

I use three filters in NPrinting to generate the table. Two of them are of the type  "Value is" or "Numeric value is" and work correctly. This specific filter should be dynamic, to always present the data filtered by the last day of the previous month. So I use "Evaluate value" with (at first) the same expression as the script in QlikView that generated this date.

I tried these expressions, all with no luck:

=Date(MonthEnd(Today(),-1),'DD-MM-YYYY')

=Text(Date(MonthEnd(Today(),-1),'DD-MM-YYYY'))

=Num(Date(MonthEnd(Today(),-1),'DD-MM-YYYY'))

=Date(MonthEnd(Today(),-1))

=Text(Date(MonthEnd(Today(),-1)))

=Num(Date(MonthEnd(Today(),-1)))

=MonthEnd(Today(),-1)

=Text(MonthEnd(Today(),-1))

=Num(MonthEnd(Today(),-1))

and all above with Now() instead of Today(). I noticed that the expressions with "Text(" will return the table, but not with te filter applied. The Num() versions leave the produced table absent (so that's not the way!)

Note:

When I just say "numeric value is" and then "31-03-2018" as the expression, the filter is set correctly. (but it doesn't work with "value is" instead of "numeric value is"). So: somehow the expression is incorrect?

Can anyone help me?

Ok then

I just tested it in my environment and i did not have any issues.

Since you are doing MonthEnd function it actualy creates a timestamp value like fore example 2018/04/01 23:59:59


try this maybe..

Can you please try using Floor function (both - in your variable when creating field and in your NPrinitng filter):

variable:


vLastPreviousMonthDay = Date(Floor(MonthEnd(Today(),-1)),'DD-MM-YYYY')



NPrinitng Filter:

=Num(Floor(MonthEnd(Today(),-1)))

hth

Hi,

I apologise for my ignorance but despite quite broad description i do not undestand what you are trying to actualy filter.

Let me give you an example how this works.

NPrinitng filters are refering to fields in your Qlik data model. Therefore for us to help you solve filtering problem thing we need to know are:

  • field name
  • go to data model viewer in QlikView and search for this field then right click and select "Preview" - get screenshot and paste
  • hover over the field ans see what data type the field inherited in the data model (ASCI, date, integer etc...)

more about filters here:

Re: Nprinting Filters not working on Excel Documents

Once we know this we will be able to establish what value needs to be evaluated in NPrinting filter and against which field.

To help us little bit more it would be good to:

  • screenshot your expressions in QlikView.
  • pull up the field you want to apply selection on as a listoboxes, apply selections in them and screenshot result in your table

I am under impression that you are mixing filters with variables which are completly different things and therefore not working for you.

NPrinting is not supporting variable triggers (or so called variable filters) see table under this link:

Hi Lech,

Thanks for replying. Here's some information.

The table has only one field, which is also the primary key, linked to two other tables. Here's the complete datamodel (Dutch language, sorry 😞

    

And here the preview content (screenshot) of the table "Peildatum":

The script I use to generate this table is as follows (the Excel-file has two dates: 01-10-2016 and 01-20-2017):

LET Vandaag=Date(Today(),'DD-MM-YYYY');

LET LaatsteDagVorigeMaand=Date(MonthEnd(Today(),-1),'DD-MM-YYYY');

Peildata:
LOAD
       Date(Peildatum,'DD-MM-YYYY') as Peildatum
FROM
[datefile.xlsx]
(
ooxml, embedded labels, table is Blad1);

LOAD * INLINE [
     Peildatum
     $(Vandaag)
     $(LaatsteDagVorigeMaand)
]
;

I'm not sure I understand your next question, but to be sure, I give you the most information I can give that I think is relevant.

In NPrinting I have this filter applied at this moment, this is working fine:

But I would like it to be something like this:

For your information: I apply this filter on the publish-task.

I hope this below is what you mean by screenshotting the listbox with the values of this table, with the one selected that I would like to be filtered in NPrinting:

If you need more information, please let me know! Thanks for helping so far!

Great - thats all what we need - let me work my ways through this example and get back to you tomorrow.

I see what you are doing now.
