How to access historical data from Jira

[b_hassan21]

Hi Everyone,

I'm trying to create reports for my organization but they need historical data from sprints,epics , how can I get that data as once we close the sprint that data is not there anywhere to find.

Thanks for any guidance

Because you could drop the issue type at any point in the search editing you're doing.

If you restrict it to just the fields for the current issue type, what do you do when the user constructs a query that might start to include the field?  

Simple answer is that you have two choices - offer everything so you can be flexible, or try to work out all the valid scenarios for a query on the fly, leading to massive performance issues as soon as anyone starts using JQL.
