Im slowly getting frustrated. 
I've set up a Service Desk with different request types, and some custom fields of which some are mandatory e.g Location.
I now created another request type where Location is not needed.
But i can't get rid of it.
Tried a few "solutions" that where posted here in the community, but they all seem to old, and don't work.
So my question is:
How can i make a field mandatory for just one request type?
Jira really is a complicated setup maze imho, seems really over-complicated for some certain stuff. and we're using it for 3 years now.
