I have READ property on both parent and child cases. An example of the condition is as follows:

1. PARENT (Condition: .Organisation = "ABC")
   1. Child 1 (Condition: .Organisation = "DEF")
   2. Child 2 (Condition: .Organisation = "GHI")

The example requirement is: When user meets Organisation = DEF, the user should only access the Child 1 case. User should not be able to search or go back to the PARENT case or Child 2 case.

However, when I do this way, I was able to search Child 1 case. However when I click to open the Child 1 case, Access Control Policy deny my access to open the instance. The error is as follows: You are not authorized to open instance [PARENT pzinskey] Access Control Policy denied access for class PARENT and action Open.

My guess is because Access Control Policy will check the PARENT case first to see if the condition is met, and then proceed to check the Child 1 case.

My question is if there is any setting/configuration to exclude this PARENT case check for Access Control Policy. Or how do I go about doing this? Any suggestion is welcome. Thank you.
