How do I change the field configuration for a single issue type in a project?

[Melanie Beaudry Desjardins]

Having difficulty understanding the relationship between screens, schemes and field configurations...

Our project has 1 issue type scheme with all the needed issue types. I need the issue type BUG to show some custom fields on all the issue operations but I can't figure out if/how I can combine 2 field configurations or 2 screen schemes for 1 project.

Hi!  You can create a field configuration that then applies 

Yes, you can create a field configuration that ties to a screen and screen scheme for each issue type. So, you can have one screen scheme for each issue type in your project that is different.

@elizabeth_jones somehow I can't seem to tie it all together and I think the existing setups in our JIRA instance are confusing me.

An issue type scheme allows me to select which issues are available in the scheme. But I can't allocate a project to more than 1 issue type scheme. So how can I have the same project use 1 issue type scheme for Bugs that's linked to a Bug specific screen scheme, and another issue type scheme for all other issue types that are linked to a different screen scheme?

I want the bug issue type to have its own different screen scheme in the same project where there are multiple other issue types included in the issue type screen.

Melanie, i am facing this same issue - did you figure out how to have more than one Issue Type  Scheme to a single project?

@Melanie Beaudry Desjardins @Tracy Gilmour you do this by creating a new issue type screen scheme, were you can define the screen scheme that each issue type is using, something like this:
