Company-managed project Scrum board is not showing sub-tasks but Kanban does

[Ilya Sadukovskiy]

We are using company managed project
While I am able to see subtasks on Kanban board 

But I am not able to see the sub-tasks on the sprint board. You can also notice that Type filter does not have Sub-task listed. Both boards are using the same saved filter that has this query: `project in ('project1', 'project2', 'project3' ) ORDER BY Rank ASC`

We are switching from Kanban to Sprint and would like to continue to see the sub-tasks on the board. Help appreciated.

I believe this is a bug since it works fine in Kanban

Good find, @Ilya Sadukovskiy !

We ended up converting sub-tasks to linked tasks.

@Ilya Sadukovskiy I am unable to reproduce the issue.

1. You confirmed that the board filter configuration does not exclude subtasks (only filtered by project)
2. You confirmed that subtask statuses are mapped correctly to the columns in the board configuration
3. The subtask is assigned to the same user (according to the first screenshot)

From the screenshot, can you confirm that your board is grouped by Assignee?

Do you have any additional boards limited to a single project of the projects listed in the board filter query?

Have you tried creating a NEW scrum board with the same settings? Are you experiencing the same issue? Do you have the same issue when the scrum board filter only shows issues from the active project?

[Ilya Sadukovskiy]

@Dave Mathijs thanks for your prompt response. Yes, the board is grouped by Assignee. 

I created this company-managed project (GEN) so I can create a combined board where I can see 3 other team-managed projects (IS, EC, VIC1). They are all active projects and have their own Kanban boards which do not show sub-tasks even when I turn on Sprints.

I tried creating a task with a sub-task in GEN (AllClear project you see) and it does show it as expected. So it appears that the team-managed sub-tasks are the issue here, but how come they are showing on a Kanban board just fine.

Hello @Ilya Sadukovskiy 

For the sprint that you are currently showing in the Scrum board, do any of the issues within that sprint actually have subtasks? The Type filter will show only the issue types that are contained in the current sprint. If none of the issues in the current sprint include subtasks, then that will not be an option under the Type filter.

[Ilya Sadukovskiy]

Yes, same ticket number IS-1185 of a task with a subtask is shown on both boards. 

[Trudy Claspill]

Oh, yes, you highlighted that and I missed it.

Have you checked the Column/Status mapping for the Scrum board to ensure that all Statuses are mapped to columns, and no Statuses are listed in the Unmapped Statuses area?

[Ilya Sadukovskiy]

Yes, in SCRUM I mapped Backlog tickets to TO DO column where in Kanban they are in Kanban backlog column. Everything else is the same and nothing in unmapped column.
