I have created multiple ritms and asset task through flow designer but I am unable to close the ritm when its respective asset task is closed.
Below is the Screenshot of flow:

@Aman_t 

are you saying you want to close RITM when last catalog task belonging to that RITM is closed?

[Aman_t]

Yes..

Basically When request is submitted then multiple ritms is created and under those ritms one asset task will create and wait checkbox is clicked so when these task is closed then another 2nd task will create and when this 2nd task is closed then the ritm which is associated to those two task should close and when all the ritms is closed which is assoiciated to the request then request state should be closed.
