BPM add-on. How to delete all tasks from 'My tasks' sections?

Hello,

A lot of tasks have been created during execution of my sample process of different versions and they are hanged on because of errors in the process.
I couldn’t continue to execute these tasks, because critical errors are displayed.
“Migrate all process instances” doesn’t help to solve the issue.

Hi,
there is no standard action to delete all tasks. You can delete the process definition itself, if you don’t need it. In the process definitions browse screen, select the process definition, click the View details button and then in the process definition details screen click the “Delete deployment” or “Suspend” button. All tasks of all process instances won’t longer be visible for users.
