If you want a user to pick attribute values from a list instead of (or in addition to) entering them manually while entering or editing a form of a business object you have to do the following:
Car
object (and you do not know all possible car types at the configuration stage), then you need to configure the CarType
object and get the Car
object to refer to the CarType
object through the reference attribute called MyCarType
. Also when defining presentation properties of the MyCarType
attribute you have to specify that the attribute should be represented by the drop down list rather than by the relationship table (see the “Presentation Options for References” section).
