Can you please elaborate your business requirement and why do you want to start it via a button?

Could you please elaborate the issue ?

Hi There,

Why you want to start the agent on click of a button?

Rather, You can start the agent activity on click of a button. In case if the work is not done, then you can call queue for agent and then from there the agent will take on.

Hope this fits your requirement.

HI Aswani,

As suggested above on click of button you can initiate a activity execution, if you don't want to execute in the current requester thread the you can use queue method instead of call.

Call ABCActivity replace with Queue ABCActivity in the activity step.

Thanks,

Naresh.

Thank you, everyone, for your response, my requirement is that on click of a button I have to start an agent(Advanced agent, stops when the job is complete) that resets SLA for all the cases in the system. 

We have delegated Goal and deadline of the assignments in business admin portal. When they change the values we want the changes to be applied to the existing assignments as well.
