I noticed that custom fields created in one JPD project cannot be reused in another JPD project. This includes such fields as "Roadmap" which seems to be a custom field automatically created when a JPD project is created.
Reusing customer fields makes it easier to maintain multiple JPD projects, that use the same fields.
Having multiple fields with the same name makes it pretty hard to create automation. Sharing fields across JPD projects solves that problem.
Thanks for the feedback Chris. You link to Field Configuration Schemes in JPD is not working for me, but I would like to read about it :)
