How can I get tp!id for a task, when a task is assigned and before it has been s

You can create a Task Report. In that report you can specify a column for the Task ID.

To provide some more context: the task is initially assigned to person X within process A. Then process B may run which updates the assignee process variable in process A. This should then automatically reassign the task to the new assignee.

I have something that works using exception flow (and without the use of tp!id)

Once a task node has been started, the assignment expression executes. This means that after starting a task node, updating the process variable used in its assignment will not change the assignment of the task.

If you want to reassign a task, I would suggest using the Task Smart Services Plug-in, found here: forum.appian.com/.../summary

You'll still need to create a Task Report in order to pull the relevant Task IDs into process B, but this will allow the reassignment to work correctly.

Hi conorc,

Thanks for the suggestion

@zubairs, create a report from designer, select report type as "Task" and context type as "Tasks by process model". Once the report is created, use a!queryProcessAnalytics() and get the required data.
