Summary

In case you need a list of tickets from different projects, an alternative is to create a filter. An example of this scenario is to display the tickets from various projects that have not been closed yet.

Solution

1. In your site, navigate to the search box at the top-right and select "Advanced issue search".
   

2. Define and run your search. This is a JQL example: 

   project in ("Project A", "Project B") AND statusCategory != Done

   
   Please note that this example will get the tickets that are not closed.
   
   

3.  Click the Save as option above.
   
4. Enter a name for the new filter and click Submit.
   
5. You can set the permissions of the filter by clicking on the "Details" link and then "Edit permissions". A window will be displayed and you will be able to configure who can view or edit the filter.
   
6. If you need to add more columns to your filter, click on the "Columns" button at the right.
   
7. To share the filter, use the "Share" option at the top-right.
   

 To access your filter in the future, navigate to the top menu and click on Filters > Your filter's name.
