Hi,
It's limited functionality designed for a pre-sales demo, great tool to learn basic functional and technical skills e.g. adding address books, order-to-cash cycle, receipts-to-pay cycle, learning RDA, FDA, TDA, BSFN, etc...
I don't know if other ERP systems has a demo product that has something like JDE can do...which users can play with anytime anywhere.
Hope this helps.
