Scheduler: How to trigger a task when a multiple task are done.

Mon, 26 Jan 2026 18:19:17 GMT

Hello Everyone,

I'm new to Qlikview. Can you guys please help me with my problem. In scheduler, I have 6 .qvw files running on the scheduler(relod) at the same time every 5mins (parallel run). They are all producing 6 different qvd files. Is there any way for me to determine when all of those qvw files are done with their execution? I need to run the final qvw which consolidates all the QVDs that those 6 qvw files produced. Please help me guys. Thank you in Advance

You can scheduled another task based on completion of multiple tasks using QMC.

Under Triggers tab, click on edit button, a pop up will open. From the dropdown in the popup choose "On Multiple Events Completed" below you have a section Task Completed in that add the tasks that needs to be completed before triggering the final application.

Hi,

You can set scheduler form Qlikview Manegement Console.

Qlikview Manegement Console -> Documents -> SourceDocuments -> Select your qvw -> Add Task -> Manually

-> Triggers -> Current Triggers -> Configure Trigger -> Start the Task - > On a Schedule -> Hourly.

now you can fix all qvw parallel reload with 5 min interval.

For final qvw

..... Start the Task - > On Multiple Events Completed -> Add your task which needed to completion.

You can chain the tasks so that one starts when the previous finished successfully. Afaik you can't make one task depend on the successful execution of more than one other task.

ya, also you can scheduled each qvw in same time by On a Schedule -> Hourly configuration.

Thank you for the information gysbert. That's actually I'm going to modify. Currently, I'm using a chain task to accomplish that. But I need to run those 6 tasks at the same time since we each task takes 30 to 40 secs to finish. So If i'm doing the chain, then 6 x 40secs = 240 secs. The final qvw that consolidates all files (from 6 qvw) needs to be reloaded every 3 mins (or 180 secs). So chain tasks will not work. Is there any work-around? Thanks

As gysbert said you can only chain one task to one task, I had a similar issue and just had to figure out which of my 5 took the longest to run and then use that to trigger the next step.

Other than that you can use a 'dummy' qvw with 'some logic' to test your QVD files and then reload from that

No, you can trigger the task "On multiple events completed" in the reload task in QMC.

But if you reload all 6 files every five minutes there might be a problem on the time constraint so that latest reloads are truly taking in to consideration.

I don't think QMC has multiple events unless you have publisher?

I can't find it in our enterprise QMC but would love to have it

Although that does require a publisher license, if I am not mistaken.

Correct.

Noted sir. But how do I do that on Reload task in QMC? There's only an option there where you can trigger the reload after single task is successful. Thank you

Nice, thank you for the screenshot. But I can't find triggers tab. Is that for the QMC? Here is my screenshot:

I think you don't have publisher license and that is the reason you are getting this view. If so, then you need to execute the tasks one after the other.

They won't exist unless you have publisher
