Common Properties

Object Field

Object fields are configured on an object. Just click on the name of each object to see the different fields. Each object field has input settings and output settings. Input settings are used when the value is sent to the external system. Output settings are used when the value is retrieved from the external system.

View Field

Common Properties View Field

Properties Description
Id This is a unique GUID which is used internally.
Name The name of the field. This could not be changed.
Label The label is inherited from the linked method. We advise not to break inheritance on view field or method field level. Change the label on object level.
