complete sprint button missing

[FSC SI BTN Atos]

I'm admin of this project and have manage sprint, start and complete sprint permissions. There is only one sprint active but however I'm missing the complete sprint button. On my board is also only one project where I have all permissions.

Hi @FSC SI BTN Atos hope you're doing well!

Please refer to this article (Completing a sprint):

If you're unable to complete a sprint, the issue might be caused by a complex board filter. In such cases, Jira Software may not be able to determine which projects are returned by the query.

1. Go to board configuration:

2. And check out the filter query:

Here are some examples of complex queries:

• assignee = someone

• project = TIS OR issuetype = Bug

• project = TIS OR (issuetype = Bug AND assignee = someone)

• (project = TIS OR assignee = A)

In addition, you could also try to search for all issues which are assigned to the sprint. Sometimes an issue was in the sprint and then gets moved to another project, for which you do not have the relevant sprint permissions.

So use the global search (JQL) and use the query (replace the ID or name):

sprint = <SPRINT_ID>

or

sprint = "<SPRINT_NAME>"
