Hi,
A likely reason why the hierarchy is not working could be the correct name and direction of the issue link specified in the configuration. The link for hierarchies shall be defined from the child’s perspective, so the Initiative level must be configured by checking how the link to Initiative looks at a Change request issue.
Please, check this article for more explanations: How to create an additional issue hierarchy.
Please, apply for support should you need more guidance.
Kindly,
Janis, eazyBI support
