Hi JocelynThank you for your feedback.Does this mean that it is not possible to limit field values in transactional applications? Our client uses custom order types and it would be easier if we could only display those.Could you please help? 

Hello Jocelyn I'm wondering if options 3 and 4 are only applicable to Fiori apps? Because we want to restrict field values "Order Type (Purchasing)" in the app "Create Purchase Order, Create Purchase Order - Advanced (me21n)". Would this be possible...
