Task with Multiple Triggers

ali_hijazi — Tue, 06 Dec 2022 09:28:58 GMT

Hello I'm working on Qlik Sense
I have a task that I want it to be triggered by the successful execution of Task 2 or Task 3
so I added two triggers does this mean it is triggered by Trg2 OR Trg3?
or it means Trg2 AND Trg3?
kindly advise

Hello,

I think that your way to go is app that starts after one is ready. You could also bypass this by scripting.

then in this case I create 2 tasks for the same QVF file
1 task that is triggered on the successful execution of Task 3
another task that is triggered on the successful execution of Task 4

G'day @ali_hijazi,

What you really need is a Group Reload Task, which I submitted as an idea last year. Maybe if enough people 'like' it, then it will get the attention of the Qlik developers.

Since we don't have that feature, we have a few options:

1. just run all your tasks every time in sequence - this is mostly fine if the tasks are short

2. use the qlik_cli, which give you the ability to write your script outside the Qlik environment to control the reloads

3. combine the apps together into a single app so that you can use conditional statements to control the flow

4. design a semaphore system where the earlier tasks store a flag file and the following task(s) read those flag files and only perform the load if the desired conditions are met.

Just a few ideas. I hope this is helpful. It is frustrating that this feature is not available OOTB.

Cheers, Barnaby.

Hi @ali_hijazi

if I understood correct, this is what you did

one task with two triggers

If that the case that is a big “OR”

best

Hello @RafaelBarrios
I did the following:
and you confirm that this task will run on the successful execution of either:
trg_ageing_schema
OR
trg_ageing_security_update

hi @ali_hijazi
sorry, i think my image was not visble, but it is the same your are showing.

and YES, your task "3 againf_balance_dashboard" will trigger when "trg_ageing_schema" OR "trg_ageing_security update" finished

considere that the task will be executed according to what you have configured in each trigger (Successfull/failed)

Hope this helps.

best,
