One Board with one filter for multiple projects

[Roger Meier]

Hello everybody,
We have about 100 projects (company-managed) with "shared settings". But the boards and filters are set up again for each project (copying an existing board and change the name). But all projects are configured 1:1 identical.
Is there a possibility that I can have only one "default board" that is used for all projects?

I think, that would be no problem. The Problem is, that i can't figure out, how to configure a filter that depends on the actual selected projekt. The filter should be somethins like "project = project.current". So every Project uses the "default board" and the "default board" uses the "default filter" (project = project.current). 

Can anybody help me to achieve that (or someting similar)?

Thanks alot!

There is no way to do this - filters do not run within the context of a project, they have to be run outside a project because they might be set up to look at other projects.  There is no concept of "current project" in Jira, it does not make any sense in most places.  The only time it could be said to be valid is when the user is looking at a single issue view, or is in one of the project screens or reports.

Jira does have a session marker for "last project this user did something with" (look at one of the project screens or reports, create an issue in it, etc), but that's not "current project" as you need it to be here.

So, TLDR: Jira cannot know what a user is thinking of as the "current project", so there is no way you can do this.  The information you need simply does not exist.
