Activity type commit rules not working

Hi ,

I have created new committ  rule with rule type ”Commit overtask type”   our expectation is PSO should commit tasks based on  task types .but its not working for me could you please suggest. 

Step:1 I have added  task types 

steps2: Created  2 commit rules and mapped with task types individually(ss1)

Step:3 Created rule collection and mapped 2 rules under one rule collection. time horizon will be the difference  one is 4r and another one is 1hr

Step:4  Mapped rule collection to a resources.

Step4: mapped same rule collection at resource level 

Thanks,

Durga
