Maintenance of Execution Properties 
Use
The execution properties determine additional processing characteristics of the single-step task or the work item that represents the single-step task at runtime.
Features
The following execution properties are recognized by the system:
Background processing
Set this indicator if the object method does not necessitate dialog with a user, and the processing is to be started automatically by the system.
If this indicator is set, the single-step task is executed at runtime as a
background work item as soon as it is its turn in the sequence. No work item appears in the Business Workplace. You can, however, find a background work item via the work item selection.If this indicator is not set, a
dialog work item appears in the Business Workplaces of the recipients. If this work item is executed by one of its recipients, the object method is executed in the background without any further dialog.
You cannot set this indicator if the indicator Object method with dialog is set for this object method.
Confirm end of processing
If this indicator is set, the end of processing of the single-step task must be confirmed explicitly at runtime. After execution of a single-step task, the system asks via a dialog box whether the processing of the task has actually been completed. It is also possible, for example, to enter an attachment at this stage.
Until this confirmation is made, the work item in question can be processed and forwarded. This may be useful if a single-step task is to be processed several times and by different people.
Executable as form
If this indicator is set, the task meets the technical requirements for execution as an
electronic form.
The system cannot check whether this property has been assigned correctly.
Form tasks always have this property. If you define a form task, you must set this indicator.
