workflow trigger BUS2000126-event Cancelled

Hello,

I'm trying to trigger a workflow when a CRM Business activity (BUS2000126) has been cancelled manualy by a user in the Web UI.

I tried to use the event "cancelled" of the BO BUS2000126.

This doesn't work unfortunately, I did notice that when I use the method "UserstatusSet" to put a Business Activity to canceled it does trigger the workflow.

Any suggestions?

Regards,

Gert
