Abstract: A method for user interface workflow composition includes defining a form of different fields, at least one of the fields in the form referencing a business object providing access to data in an external data source that is different than at least one other data source for a correspondingly different one of the fields. A set of references to both human steps and automated steps of a workflow is loaded such, each human step referencing a corresponding user interface and each human step and automated step individually including contextual data. A human step is generated for the defined form and loading into the module. Graphical elements, each representative of a selected human or automated step, are visually placed into a canvas along with an individual graphical element representative of the defined form. Transitions are defined between the human and automated steps represented by corresponding graphical elements setting forth a user interface workflow.
