Modeling guidelines for activities
Process
If the
Ad hoc attribute is
= True, the
Completion condition attribute must be specified.
If an ad hoc process is refined, no sequence flows must be modeled within the assigned model.
Subprocess
If the value
Independent is set for the
Subprocess type attribute, the
Process reference attribute must also be specified.
If the
Transaction attribute is enabled for a subprocess, the
Transaction ID attribute must also be available.
If the
Loop type attribute is specified, the
Loop condition attribute is also required.
If models are to be transferred to BPEL4WS, a check is recommended to determine whether the
Loop type attribute is set to
Maximum for processes with the value
Standard.
If the value
Standard is specified for the
Loop type attribute, the
Test before attribute is also required. The
Test before attribute should be disabled by default.
If the value
Multi-instance is specified for the
Loop type attribute, the
Parallel instance generation attribute is also required. The
Parallel instance generation attribute should be disabled by default.
If the
Loop type attribute of a subprocess has the value
Multi-instance and, at the same time, the
Parallel instance generation attribute is enabled, the
Loop flow condition attribute must be specified as well.
If the value
Complex is set for the
Loop flow condition attribute in a process, an expression that determines when and how many process markers are passed on after the subprocess is complete must be specified for the
Complex attribute.
Task
If the value
Receive is specified for the
Task type attribute, the function should not have any outgoing message flow connections.
If the value
Send is specified for the
Task type attribute, the function should not have any incoming message flow connections.
If the
Task type attribute is not specified or the values
Script or
Manual are set, the function should not have any incoming or outgoing message flow connections.
For functions whose
Task type attribute is set to
Abstract, the
Abstract type attribute must also be specified. In addition, these functions may be used only in pools of the
Abstract type or in
Collaborations.
