Hello Atul,
looking at the above messages, I believe that the constraint is not triggered (we cannot see the part at the bottom saying 'Use of Constraint...' with the variables (PC.CH_....) evaluated, here how it should look like:
This could be due to the dependency status (Locked / not released).
Could you please check the constraint dependency status in the Basic data:
It shout be 'Released'.
Please also check the Dependency net status, again 'Released'.
Hopefully it should work......
Thank you and regards,
Flavio
