Dear all,
May I ask if multiple instances can be generated by submitting one forms.
Not directly, but you can have a form start a process, then use a workflow service task and a workflow to invoke other processes or split the instance into many instances.
Thanks for your answer.
'split the instance into many instances' -- Can these split instances be displayed separately on the monitoring? And which workflow activity can split the instance?
Yes they will be displayed separately, they will be entirely separate instances.
Create Process 1 with a message start event and a workflow service task. You will need to then create a workflow that uses a retrieve business process variables activity to get all the data from Process 1. The workflow can then use an Invoke Business Process activity to kick off a new Forms instance. The workflow can invoke as many processes as you'd like.
Ultimately, it splits that initial Process 1 instance into many instances of the same or other processes.
