Hi @Pedriel , We had the conversation directly at [support@eazybi.com](mailto:support@eazybi.com). But I will share the first answer here as well for other users. You can use issue links to create an additional issue hierarchy in the Issue dimension. Those additional issues hierarchies need to have a strict structure in Jira to be defined in eazyBI: 1. Each child issue has only one parent issue 2. Each issue type is used only in one issue hierarchy level. If each Epic can have only one Parent issue, then you can check this documentation on how to create a hierarchy in eazyBI based on those links: [https://docs.eazybi.com/eazybi/data-import/data-from-jira/advanced-data-import-options/additional-issue-hierarchies](https://docs.eazybi.com/eazybi/data-import/data-from-jira/advanced-data-import-options/additional-issue-hierarchies) Also, here you can see a detailed explanation in eazyBI Community on building hierarchy: > [@How to create an additional issue hierarchy](https://community.eazybi.com/t/how-to-create-an-additional-issue-hierarchy/9793): > > In Jira, bigger tasks can be split into smaller pieces; thus, we can create task groups that are linked together but can be worked on separately. For example, an Issue can be grouped into smaller sub-tasks. Or an Epic can be split into Stories. eazyBI recognizes those structures and creates different standard hierarchies in the Issue dimension: the default hierarchy with Project → Issue levels, the Sub-task hierarchy with Project → Parent → Sub-task levels, if you have imported the standard Ep… best, Gerda // [support@eazybi.com](mailto:support@eazybi.com) --- _[View the full topic](https://community.eazybi.com/t/hierarchy-filtering/12807)._
