Single-step task as a single step
It is not always necessary for a complex workflow definition involving several steps to be executed to process a business task. Often a single step in the form of a standard task can perform the function required.
Single-step task as part of a workflow definition
A single-step task can be part of a workflow definition as a step of the type activity. In the workflow definition, additional information can also be specified regarding responsibilities and deadlines.
If dialog with a user is required to execute the single-step task, all
possible agents receive a dialog work item in their Business Workplaces. If one of the recipients executes the work item, the relevant activity is executed.Integration
Single-step task activity
You define the activity of the single-step task using an
object type method of one of the object types defined in the Business Object Builder.Possible agents of single-step tasks
The
possible agents of a single-step task are specified in the relevant definition. These possible agents can be defined with reference to the organizational plan of the enterprise, with the consequence that the same task is offered for execution to several users, who have the same authorizations from an organizational perspective, in their Business Workplaces.If the task is reserved by a recipient, it is removed from the Business Workplaces of the other recipients.
If the task is used within a workflow, you can define
responsible agents in the workflow definition. The recipients of the work item are all users who are both responsible agents and possible agents.Prerequisites
The object type method and the object type are defined, tested and generated.
You do not have to have defined the object type and its methods yourself. You can also use methods supplied as standard.
