Hi all,
I wanted to auto-populate a custom field named scope category when I create,
- subtask under a backlog (below snap of the rule - this works fine ) . In the create screen the value will not be auto populated but after the subtask is created, if I open the subtask this scope category field is there. I am fine with this result.

- But I also want to have the scope field when I create a bug linking it to the backlog. Then want the scope field to be present. But I am not able to achieve this. Find below the rule;

Please help me to achieve the second scenario.
Thanks,
Thinesh
