Prevent error or warning message when report is empty

Danijel — Mon, 16 Jan 2023 09:44:11 GMT

Hello All,

There is a NPrinting report distributed to some people. Some of them do not always have data, so they do not get a report. So far ok.

But: I receive a warning or error mail from NPrinting about this, that filter XY is faulty, because no data is available.

In this case it is not a problem if there is no data. How do I manage to set it up so that no message is distributed by Qlik.

Thanks and greetings

Do you receive those messages as admin? based on admin notifications settings?

Do you get email as report recipient with message instead of attachement?

Both settings can be controlled by:

report settings

and here admin settings

Hi @Lech_Miszkiewicz ,

I get the error message as admin. The affected user does not receive an email because it is the only report in the task.

In the second link I can't find any way to differentiate that only if the report is empty that no error email is sent.

Greetings

thats right - the second setting is about the level of monitoring. You are likely having a level of Warning and Error enabled which also sends email to you when the warning appears in logs, am I correct?

Correct, for me warning and error is active.

As I said, the only "problem" when due to non-existent data (due to filtering) no report is generated and from this a warning error message arises.

Because it can happen in the case that affected users just on the day no report, which is ok.

Only administratively it is a problem, since one receives then again and again such "wrong" error messages.

Well, then change your logging level to only send emails on Errors.

NPrinting does exactly what you wanted - sends email when there is a warning, right?

The way I deal with situations like this is by ensuring that my data model ALWAYS has all values available for filters to be applied and by implementing report condition for the report to be sent or not.

Yes, that is correct. But in this case it is OK that it is not defined as an error.

I have already tried with a condition -> Chart empty, but then I still receive said mails.

Hi,

They are two different things. The email for admins doesn't contain data and has the goal to notify admins that an event happened. As admin you can select in which cases to receive it. Select Warning level is useful, in general, during the development.

The conditions instead will determine if a publish task or a report in a task will be created. If yes the report will be delivered with data to the final user.

Best Regards,

Ruggero

Hi,

I understand what the difference is. I just want to minimise the effort for the admin, for such topics that do not represent a real error in this case. Technically, it is clearly an event for NPrinting that needs to be reported.

What I have now tried: I have created a condition that says chart XY has values. This condition is in the publishing task with the value True. However, this does not seem to have any effect, because I get exactly the same messages as before.

Actually, the condition should happen on a user basis, but I can't find an option for it here.

Greetings

Hi @Danijel

your condition should be applied to report (setting is done on report level in task) and the most important thing is that you need to make sure that combinations of filters for each user exist in data model. That will allow for filters to be applied but report not sent as it will have no values.

Applying only condition will not work as lack of possibility to apply filter will still result in warning.

Okay, thanks. Then I will try it that way.

A general question that the help page could not answer:

What is the difference between error and warning and what kind of events do each contain?

Thanks and greetings

Hi,

In Qlik NPrinting, an error typically indicates a problem that prevents a task or operation from being completed successfully.

A warning typically indicates a less severe issue that does not prevent a task or operation from being completed, but may impact the results or functionality in some way.

After an error a publish task stops instead after a warning it will continue.
