Pausing service task flow

Hi All

I have a Main BPMN process has 5 service tasks. Process can get cancel request ( as sub process) we will validate the cancel request before cancelling the BPMN running process .

My query is that how we can pause BPMN service tasks while validating the cancel request . If cancel request is validate then cancel the BPMN flow else start paused BPMN flow .

Thanks in advance

How are the service tasks implemented?

Hi Niall

Thanks for quick reply . Service tasks are implemented as external tasks
