Trigger in QlikView management control - multiple event

[Ranjanac1]

Hi Team,

one of the Task is dependent on 3 other tasks.. so all the other 3 tasks are dependent on each other.. 

For example:

So, instead of kicking this one by one...

I have tried to create a trigger " on multiple events completed". but its not working out... Could you please assist..?

Thanks & Regards,

Ranjana
