How do I restrict a group from creating specific issue type?

[Jacob Piotrowski]

In our project we have introduced two different ticket types with separate workflows:

BUGS (with bug workflow) reported in lower level environment by group A

and

DEFECTS (with defect workflow) reported in higher level environment by group B

I now want to restrict permissions for group B so that they are not able to create BUG tickets while group A can still create both BUGS and DEFECTS.

I believe I should set this up on the create transition in Bug workflow

And I think it should be set in transition properties but I'm not sure what to put in the property key & property value fields.

Or perhaps there's another way to achieve this?

Thanks

@Jacob Piotrowski I suggest you go with a validator route, and perform User in Group validation on creation of particular issue type. (Also remember create transition doesn't have support for condition).

Otherwise I think you will need plugins like ScriptRunner.
