Hello,
Similar questions have been posted. I read them and can't find an answer that has worked for my situation. Sorry for the long post!
The company I work for is using Jira Software Data Center v9.4.20 for work management purposes. Our Jira system is configured so an Epic (parent ticket) is created in the 'New Work Request' status when the customer submits a request. When the Epic transitions to a particular status one or more Deliverables (child ticket) are automatically created in the applicable Jira project, and linked to the Epic.
Each deliverable will have zero to many linked sub-tasks. Sub-tasks are like a checklist of activities that need to be completed (DONE status) before the Deliverable can be set to DONE status. Once the Deliverable is DONE the Epic can transition to the next status in the workflow.
I am tasked with writing a board filter, for one of the support team, that retrieves their deliverables and it's link subtasks and displays them on the board grouped by Epic. They board query appear to be retrieving the correct data however I have an issue with the way they are being displayed on the Kanban board.
For instance I have two deliverables, that were set up identically via an automation rule but are behaving differently. One displays the linked sub-task directly under the deliverable on the Kanban Board, while the other does not. Refer to attachments for supporting information.
