Set Analysis strange behaviour when all rows are null

kevpickering — Wed, 23 Jan 2019 12:16:53 GMT

Hi,

I've attached example file that demonstrates the issue I'm experiencing. The text box displays 43 out of 43 - which is number of measures that have passed out of total measures. The table below it displays all rows.

The set analysis in the text box works correctly if at least one of the rows has the field ComplianceAttribute.ValidationResult populated. If one row has a 'Pass' or 'Fail' in the field, the text box will correctly display 1 of 43 or 0 of 43.

However, as you can see, the field is null in every row. So I would expect to see the text box display 0 of 43, however the text box is displaying 43 of 43!

Is this a bug or am I missing something - I haven't come across this before.

I'm using QlikView desktop 12.20 (November 2017 SR7).

Any help would be appreciated. Thank you.

This is a known issue and has been brought up several times. I think one way around this is to replace null with some kind of blind space or use a flag to assign nulls, passes and fails a different number and then use that in set analysis.

Thanks for the feedback. Yes I've worked around the issue with other solutions but was hoping not to.
