In some of the repetitive data entry areas, like forms to enter purchase invoices, it used to have the most productive UI I have ever used. The cursor started in the right box, tabbed to the right places etc. I would swap that screen for my current modern one any day
This is the feedback I've got while working on a customisation project based on a different ERP (red one). Users actually expect your interface to behave in the exactly same way as their ERP does (TABs and keyboard shortcuts included).
