Context

Report generation is performed in several parallel threads or processes, eventually on different OS-processes, virtual machines or containers. Cancelling or aborting needs to handle distributed execution.

Trigger

User has (accidentally) started report generation, but now wants to interrupt and clicks abort or cancel button or selects cancel-function via keyboard.

Acceptance Criteria

• System interrupts report generation
• Current generation state saved (in case user wants to continue later)
• Control returns to user interface
• User gets back full keyboard or mouse control within at most 10 seconds
• All backend generation tasks or processes have acknowledged abort/cancel signal
