I'm trying to update the summary of a couple of subtasks from Excel.
I exported to csv, no issue (with key, id and parent id).
Changed the values but when I try to reimport, the wizard gives me error about the mapping. I can't map the Issue Key field like it's mentioned in the documentation because the field does not exist in the Jira field list when doing the mapping, but I can map Issue Id and Parent Issue Id just fine.
What else do I have to do for it to work...
