Correct use of conditionals in Qlik Nprinting

[Richard3]

Create a condition so that the report is sent only if there are errors, for that I create a variable called vCantidadErrores, which tells me the number of errors observed, and place the condition in the report vCantidadErrores > 0 is true it is sent, but if it is not mayor the mail is also sent, what can I be doing wrong?

I say your variable is not expanding as explained in documentation: https://help.qlik.com/en-US/nprinting/May2023/Content/NPrinting/Troubleshooting/Variables-dont-expan...

So the questions are:

• how is your variable created?
• is it constant or expression
• if it is expression does it expand? (do you have = sign in front of the expression definition)?

I would also use reference where variable is equal to a value, like:

• say you can set it up so it is vCantidadErrores = 0 with FALSE to be used as a trigger

but as I said before - I think you made a mistake and your variable probably does not expand so check that first.

The variable is created in the Qlik Sense upload script.
I have it defined in the condition as a constant.
Attached the detail for anything else you can see.

that is 25% of what we need... another 75% of information we need is:

• How does the variable look in Qlik Sense variable editor?
• That will give us answer if value of variable set in script evaluates to a number you want it to
• Also, once you reload the app - how much time after you run your NPrinting report?
  • just for testing - have you tried re-generate metadata before running report/task so the condition could be evaluated?
